Trajectory Optimization in Face Milling Operations: Impact on Costs, Energy, and CO₂ Emissions

Trajectory Optimization in Face Milling Operations: Impact on Costs, Energy, and CO Emissions Face milling is a fundamental machining operation used to generate flat surfaces with high precision. Traditionally, it has been optimized based on parameters such as cutting speed, feed rate, and depth of cut. However, the trajectory followed by the tool also plays a crucial role in the overall efficiency of the process, both in terms of energy consumption and the usual effects on tool life, productivity, and surface quality. Types of trajectories in Face Milling Thanks to the development of CAM systems, we now have a wide range of options for machining trajectories for roughing and finishing surfaces. Among all these options, there is a main difference: some operations keep the tool always in contact with the workpiece, while others include idle (non-cutting) movements. We can classify them into four basic categories: Unidirectional : The most basic and easiest operation to program. The tool works with linear trajectories in the same direction and returns without cutting. Acceptable surface finishes are obtained, but if direct entry is used, it can affect tool life and increase the total cycle time. Zig-zag (bidirectional) : Linear movements with the tool moving in both directions, reducing idle times, but with negative effects on the resulting surface quality. Managing the changes in direction can affect tool life. Spiral: Either towards or from the inside of the workpiece, it allows for continuous cutting with controlled engagement, offering good surface finishes and good control of tool life while reducing machining times. Adaptive and trochoidal : Trajectories that optimize tool-material contact by maintaining controlled radial engagement, improving surface quality. They usually include small idle movements in hard-to-reach areas but aim to keep the tool in contact as much as possible. They are highly recommended for difficult-to-machine materials. Each of these trajectories has different implications in terms of machining time, workload, energy consumption, and heat generation. CO Emissions In this article, we will mainly address the energy effect of trajectories by comparing those that maintain constant contact between the tool and the workpiece with those that, due to their configuration and different orientation, involve idle (non-cutting) movements. To illustrate this comparison, we will use, an alternative unidirectional trajectory and a spiral trajectory from the outside, both under the same cutting conditions, and compare the energy consumption of both options. Subsequently, we will compare both trajectories with improved cutting conditions. We can calculate the power consumed on different materials, selected from a wide data base, and using specific combination of tools and inserts geometries, during a milling operation using “ToolGuide,” available at this link. ToolGuide For a face milling operation with the CM345 ref 345-050Q22-13H Z6, with inserts 345R-1305M-PM 1230, on a 32CrMoV12-28 P3.0.Z.AN steel workpiece with 230 Hb, we will start from these two cutting conditions, which will give us two different cutting power consumptions. During rapid movement at speeds of 5,000 to 10,000 mm/min (without cutting load) on a conventional 5-axis CNC machine with a maximum power of 40 kW, typical energy consumption ranges between 4 and 7 kW. For our example, we will use 5.5 kW as the calculation value. The components that make up this basic machine consumption are: Software and electronic equipment of the machine. Machine movement, plus the rotation of the cutting spindle itself. The higher the feed rate, the greater the energy demand. Machine movement, plus the rotation of the cutting spindle itself. The higher the feed rate, the greater the energy demand. This range is useful for estimating energy consumption during rapid positioning phases or movements between operations, especially in intensive machining cycles. Case Studies Case 1: Unidirectional vs. Spiral trajectories. In a face milling operation on a 250x250 mm steel plate, two trajectories were compared: unidirectional and spiral. The spiral trajectory has a total cutting length of 1,250 mm, which is equivalent to 38.26 seconds of cutting time. In the unidirectional trajectory, there are 5 paths of 300 mm each, and we must add 4 return paths with a table feed of 7,500 mm/min. This allows the total machining to be completed in 45.918 9.6 55.51 seconds, an increase due to the non-cutting return time. The cutting power is 16.7 kW, and the power consumed during idle movements is 5.5 kW. Therefore, the total energy consumption during the cutting time is 0.2276 kWh for the unidirectional trajectory and 0.1774 kWh for the spiral trajectory. The graph provides a clearer view of the kWh savings. Comparison between unidirectional and Spiral trajectories Case 2: Comparison between original and higher Fz0,4 cutting conditions. We have already seen how idle movements of the machine affect energy use. Now, if we take our second set of cutting conditions, with a feed per tooth of 0.4 mm, we can observe the effect of increased cutting parameters on both energy consumptions. The working power will increase to 18.1 kW, but the cutting time for the spiral trajectory will decrease to 33.48 seconds. In the unidirectional operation, the cutting time will be 40.17 9.6 50.07 seconds. Therefore, the new total energy consumption during cutting time is 0.2166 kWh for the unidirectional trajectory and 0.1683 kWh for the spiral trajectory. This is a counterintuitive result, cause with higher cutting power, we obtain lower energetic total consumption thanks to cycle time reduction. Increase feed on unidirectional trajectories effect Increase feed on unidirectional trajectories effect Energy and CNC Machine Cost Analysis by Region The following table presents a comparative analysis of energy costs, CNC machine hourly rates, and average CO emissions per kilowatt-hour (kWh) across different regions. This data is useful for evaluating the environmental and economic impact of CNC operations globally. And here are the data for all the cases studied. kwh y CO2 emissions and cost based on average data for all regions. Conclusion The choice of trajectory in face milling operations not only affects quality and productivity but also has a direct impact on process sustainability—energy costs, direct machine costs, and CO emissions into the atmosphere. Adopting optimized trajectories through advanced CAM software allows you to: Improve energy efficiency. Reduce tool wear. Decrease CO emissions. Lower direct machining cost and increase productive capacity. For CO consumption, the reduction is 26% when comparing the unidirectional trajectory with Fz0.35 to the spiral trajectory with Fz0.4. This also results in a 40% economic reduction . In an industrial environment increasingly focused on sustainability, these technical decisions can make a significant difference. Selecting tools that allow us to work at the highest cutting conditions will achieve both direct economic savings and reductions in CO emissions.

Mastering high-volume hole making

Overcoming common drilling pain points with CoroDrill DE10 High-volume drilling requires precision, efficiency and reliability to meet demanding production schedules and maintain cost-effectiveness. For manufacturers, these requirements often pose challenges, such as ensuring tool longevity, achieving consistent hole quality and minimizing downtime. So, what’s required to achieve more efficient hole drilling in an increasingly competitive environment? Here, Mikael Carlsson, Global Product Specialist for Indexable Rotating Tools at Sandvik Coromant, explains how a new drilling innovation could reinvent high volume hole making. Several shifts in manufacturing trends are increasing the demand for high volume drilling. Producing electric vehicles (EVs), for example, requires drilling thousands of precise holes in battery enclosures and thermal management systems, intensifying the need for reliable, scalable solutions. Similarly, renewable energy sectors, such as wind and solar power, rely on high-volume drilling for producing key components like wind turbine shafts and solar mounting systems, where accuracy and durability are paramount. In industries where efficiency and reliability are non-negotiable, finding solutions that balance these demands is critical. Drilling down the challenges High-volume hole making often reveals challenges that can be underestimated, even by experienced manufacturers. Many already recognize the critical importance of tool wear and cycle times, but it is the hidden complexities of high-speed and high-penetration operations that can profoundly impact productivity and operational efficiency. Take, for example, thermal and mechanical stresses encountered during the drilling of thousands of holes — especially in typically more challenging materials like hard steels and heat resistant super alloys. These forces can lead to accelerated tool fatigue, burr formation or even deformation of the workpiece. Such challenges go beyond tool durability. They involve understanding the interplay between the tool's geometry, coatings and material composition with the specific characteristics of the workpiece. Effective heat dissipation, resistance to microfractures and the ability to maintain edge sharpness over prolonged use are all crucial factors for ensuring consistent quality across extended production runs. Another consideration is the cost impact of seemingly minor inefficiencies, such as setup or tip changes. In large-scale operations, for instance, even a small amount of downtime per shift — whether due to recalibrating machines for a new tool or replacing worn-out tips — can accumulate into substantial productivity losses. These inefficiencies highlight the importance of streamlined solutions, such as systems designed for quick setup, precise alignment and easy tool changes. Additionally, eliminating unnecessary steps in the drilling process can drive significant time and cost savings. For example, tools that remove the need for pilot holes or pre-setting equipment can drastically reduce cycle times and minimize the reliance on operator intervention, thereby increasing overall process stability and throughput. Addressing these pain points with thoughtful planning and optimized tooling strategies is essential for manufacturers striving to meet the demands of high-volume production without compromising on quality or efficiency. A streamlined approach Introduced by Sandvik Coromant in March 2025, CoroDrill DE10, an advanced exchangeable-tip drill designed for high-volume hole drilling, aims to address these drilling challenges. CoroDrill DE10 is shown to boost productivity while streamlining operations, due to its advanced -M5 tip geometry. This innovative design achieves an ideal balance between high feed rates and precise penetration, enabling the tool to deliver exceptional performance across diverse materials. From steel alloys to stainless materials, CoroDrill DE10 can ensure consistent hole quality while also minimizing the risks of burr formation or workpiece deformation. A crucial feature of CoroDrill DE10 is a patented pre-tension clamping interface, which combines familiar design with enhanced security. The interface enables fast and easy tip changes without spare parts, ensures reliable drilling at high feeds and speeds, delivers superior clamping strength and achieves straighter holes with tighter tolerances. It also extends drill body life, making CoroDrill DE10 the most robust exchangeable-tip drill of its kind. Furthermore, CoroDrill DE10 also eliminates the need for pilot holes to further streamline workflows and reduce cycle times and inventory complexity. Its robust design supports extended tool life, with more tips per tool body, which ultimately drives down the cost per hole. As a plug-and-play solution, CoroDrill DE10 integrates effortlessly into existing setups, making it a practical upgrade for manufacturers looking to enhance productivity without overhauling their systems. It also integrates seamlessly with digital machining systems through Sandvik Coromant's CoroPlus platform. This compatibility provides operators with precise cutting data and real-time performance insights, so parameter settings can be optimized and tailored to specific materials and applications. Operational and cost-saving benefits Several success cases have highlighted how CoroDrill DE10 drastically improves productivity in high volume drilling. In testing conducted in Italy, CoroDrill DE10 demonstrated significant performance advantages over a competing tool while drilling AISI316L stainless steel. The case involved 52 mm through and blind holes, using emulsion coolant at 70 bar. CoroDrill DE10 achieved a remarkable 57% increase in productivity and 43% longer tool life compared to its competitor. The tool also delivered excellent hole surface quality, consistent chip control and sound-level performance aligned with expectations. The tool’s robust design and advanced -M5 tip geometry ensured reliability and repeatability — and both were key factors for the high-value components in this application. With a higher feed rate, extended tool life and reduced need for downtime, CoroDrill DE10 proved to be a cost-effective, efficient and sustainable solution for high-volume drilling in challenging materials. In another case, an automotive manufacturer faced issues with high cutting forces deforming its drill bodies, specifically while machining gearbox housing components from 47CrMo4 alloyed steel. This issue led to tool failures and increased costs. Instead, switching to CoroDrill DE10 resolved these challenges. Using a feed rate of 0.35 mm/rev at a depth of cut of 2.5 times the drill diameter, the tool delivered a 17% productivity boost. As in other applications, CoroDrill DE10's robust design and patented pre-tension clamping interface ensured exceptional accuracy, extended tool life and minimized downtime. These examples demonstrate how CoroDrill DE10 meets industry needs while offering significant operational and cost-saving benefits. High-volume hole-making demands precision, durability and efficiency, making it essential for manufacturers to overcome its challenges to achieve greater productivity and remain competitive. With its advanced features, tools such as CoroDrill DE10 offer a new perspective on drilling, and a strategic solution for the future of manufacturing.

Unlocking the benefits of multi-material drills

Versatile drilling offers a key to more productive manufacturing In January 2025, the World Economic Forum reported that facilities identified as part of its Global Lighthouse Network are achieving remarkable productivity gains of 70%, while simultaneously reducing energy costs by 40% and time to market by 40%. Lighthouses aside, how can all manufacturers raise their productivity, without increasing costs? Here, James Thorpe, Global Product Manager for Hole Making and Composite Machining at Sandvik Coromant, explains how a new drilling tool can enhance manufacturing production goals for multi-material applications. Beyond the Lighthouse facilities, manufacturers across the globe are increasingly tasked with producing parts from a diverse array of materials — from hardened steels and composites to softer metals and plastics — all while striving for uncompromising precision and efficiency. Addressing these challenges head-on requires tooling solutions that not only push the boundaries of traditional drilling capabilities but also streamline operations in an increasingly competitive market.  Overcoming pain points   Drilling is a fundamental yet technically demanding operation in modern manufacturing. One of the most persistent challenges involves material variability. Manufacturers often work with a wide range of materials, from tough hardened steels to lightweight but ductile metals. Each material presents unique difficulties —hardened steels can cause excessive tool wear, while softer metals may deform under drilling forces.  Heat generation and tool wear are also significant concerns in drilling operations. High cutting speeds, prolonged machining cycles and demanding material compositions contribute to excessive heat buildup. This not only accelerates tool degradation but also impacts machining accuracy, leading to surface defects and deviations from required dimensions. Effective heat management solutions, both in tool design and machining strategies, are therefore critical for extending tool life and improving component quality.  Another key challenge is chip evacuation. In deep-hole drilling or high-feed applications, inefficient removal of chips can lead to clogging, increased heat generation and even tool failure. Drill flutes must be designed to facilitate smooth and consistent chip evacuation, preventing operational disruptions and maintaining stable machining conditions.  Process stability is equally essential for precision manufacturing. Accurate hole positioning and straightness are critical for high-quality components used in sectors such as aerospace and automotive. Any deviation can compromise the functionality of the final product, leading to costly rework or component rejection. Achieving and maintaining stability requires a combination of robust tool geometry and optimized machining parameters.  Lastly, manufacturers face growing pressures to adopt sustainable and cost-effective production practices. Reducing waste, extending tool life and minimizing energy consumption are priorities as companies strive to meet both economic and environmental goals. These factors drive the demand for drilling tools that deliver superior performance while lowering the total cost per part.  A drill for all materials    To boost productivity and maintain cost-efficiency, there’s a growing need for versatile drills that can handle multiple materials, eliminating the need for frequent tool changes while lowering tooling costs. Advances in coatings and tool design enable these multi-material drills to perform well without compromising quality, offering both cost savings and improved sustainability.  A prime example of this is CoroDrill Dura 462, which is specifically engineered to enhance performance across a wide range of materials. Featuring a fine-grained cemented carbide substrate, CoroDrill Dura 462 offers exceptional wear resistance and reliability with a well-controlled microstructure that ensures consistent results, even when working with challenging materials like hard metals or ductile alloys. This makes it an invaluable tool for manufacturers seeking uniform precision and stability, no matter the material composition of their components.  CoroDrill Dura 462’s geometry is designed with versatility in mind. The tool’s point design significantly reduces cutting forces, improving positional accuracy, especially in high-tolerance applications. The drill’s clearance angles reinforce point strength, while its single-margin configuration helps minimize heat buildup, further enhancing tool stability and overall performance.  Further enhancing its performance is Sandvik Coromant’s patented Zertivo 2.0 PVD coating, which, alongside the fine-grained carbide substrate, provides superior wear resistance and enables high-speed drilling while maintaining process stability.  Benchmarking results have shown the tool’s clear competitive advantage. In one customer case, CoroDrill Dura 462 increased productivity by 110% and extended tool life by 36%. Another case demonstrated an 85% productivity gain and a tool life that more than doubled compared to a low-cost competitor.  While WEF's Lighthouse facilities guide the industry toward more efficient manufacturing, manufacturers need the right tools to navigate the complexities of multi-material production. By adopting versatile solutions that tackle material variability, heat management and process stability, they can chart a course toward significant productivity breakthroughs and operational excellence.  Learn more about CoroDrill Dura 462 Sandvik Coromant info.coromant@sandvik.com Unlocking the benefits of multi-material drills Multi-material Drill Benefits Learn how multi-material drills improve productivity and efficiency in manufacturing.

Master the unmachinable with CoroMill® Plura composite 2P350

Master the unmachinable with CoroMill Plura composite 2P350 Machining composite materials remains one of manufacturing’s toughest challenges. Abrasive fibres, layered structures and sensitivity to heat and vibration often result in unpredictable cutting behaviour, delamination and accelerated tool wear. Their poor thermal conductivity means composites are usually machined dry, making heat even harder to control. So what does it take to machine these materials more efficiently and with greater confidence?  Here, our experts in solid carbide end milling tools at Sandvik Coromant explain how. Composite materials, especially carbon and glass fibre reinforced plastics (CFRP/GFRP), impose unpredictable cutting forces that can vary dramatically depending on fibre direction, resin content and manufacturing method. Conventional tools can dull quickly on hard fibres, while excessive cutting forces or improper geometries often cause delamination or leave uncut fibres. The result is inconsistent performance and elevated scrap rates. The serrated router,  CoroMill Plura composite 2P350 , was developed to address these challenges directly, offering sharper, more durable edges and a geometry optimized for stable, low-defect machining. This is a significant step forward in stability, quality and process security when working in demanding composite applications. Patented dual cutting mechanism A crucial feature of CoroMill Plura Composite 2P350 is its patented serrated geometry, designed to deliver a balanced, scissor-like dual cutting action. This coordinated mechanism effectively clamps and shears the fibres, reducing cutting forces and counters the tendency of composite layers to split and delaminate or produce uncut fibres. The geometry balances cutting loads across all flutes, preventing any single tooth from taking excessive force. This results in lower and more consistent cutting forces compared to traditional routers, protecting both the tool and the workpiece. Reduced cutting forces also contribute to better surface finish and less risk of delamination or uncut fibres. By disrupting harmonic vibrations, the geometry also contributes to a more stable and quieter machining process. The controlled cutting action not only improves surface integrity but also enables reliable one-pass machining, supporting both process security and a more comfortable sound level in the workshop. A grade for abrasive composite environments The introduction of grade O2AD marks a significant breakthrough for tool life and long-term stability. Composite materials are extremely abrasive, and tools often lose sharpness quickly if not specifically engineered for these conditions. Grade O2AD is developed specifically to combat these challenges, featuring an optimized CVD diamond coating and a tailored substrate that enables great adhesion between the two. The synergy between the coating and the substrate helps maintain excellent edge-line sharpness for optimal cutting action, ensuring excellent abrasive wear resistance, longer tool life, more predictable performance and less frequent tool changes. Internal tests and customer evaluations show that grade O2AD can double the tool life compared to the previous grade O12M, delivering clear gains in productivity and cost efficiency. Performance in aerospace and beyond CoroMill Plura composite 2P350 is particularly well-suited for the aerospace industry, where composite components must meet strict structural and dimensional requirements. The tool has shown strong performance when machining fuselage frames, wings, stabilizers, spars, ribs, floor beams and other critical structures. The tool’s reliable behaviour across slotting, ramping and edging operations contributes to a more predictable machining process with less scrap and rework, which is especially valuable in high-value production environments. Adding the ability for one-pass machining in these operations, it contributes to fewer secondary operations. Simultaneously, the large flute volume enables efficient chip evacuation and high material removal rates, boosting productivity.  Beyond aerospace, industries such as automotive, defence, space and nautics benefit from the tool’s controlled cutting and consistent results, making this tool a versatile option for a broad range of applications.  Beyond aerospace, wider industries such as automotive benefit from the tool’s controlled cutting and consistent results, making this tool a suitable option for a broad range of industry segments and applications. The full portfolio CoroMill Plura composite 2P350 with grade O2AD represents a major advancement in composite machining tooling. Through its patented cutting geometry, optimized diamond coating and proven performance across demanding applications, it provides the process security and productivity needed to machine one of the industry's most challenging materials.  For even more specialised composite operations, CoroMill Plura composite 2P350 is supported by a wider portfolio. CoroMill Plura composite 2P460 compression router is ideal for components with woven glass layers on both sides, providing excellent vibration control in thicker materials through its overlapping flute design. For finishing operations, CoroMill Plura composite 2P050/2P051 low helix routers enable smooth, burr-free edges in composites and CFRPs, with right/left helix options for improved fixture stability and high-feed capability.  Together, these tools form a complete portfolio designed to help manufacturers achieve consistent, high-quality results across the full spectrum of composite machining challenges.
