This is an example of analysis regarding the issues of "Although the cutting volume was kept constant, the tool was damaged due to machining titanium alloy with a shallow cutting depth" and "Although the cutting volume was kept constant, the surface finish of the aluminum alloy machining deteriorated." The analysis using 'ProductionModule' evaluates tool damage and trial surface finish characteristics. By evaluating the cutting load during machining in detail rather than using a simplified method based on cutting geometry, it becomes possible to optimize the cutting simulation process considering machining time and tool life, including the spindle power of the machine tool and tool torque. 【Issues】 ■ Although the cutting volume was kept constant, the tool was damaged due to machining titanium alloy with a shallow cutting depth. ■ Although the cutting volume was kept constant, the surface finish of the aluminum alloy machining deteriorated. *For more details, please refer to the PDF document or feel free to contact us.

This is an example of building an NC data optimization system using the 'Production Module' that performs physical simulations on CAD/CAM. When the product dimensions do not match the CAD/CAM model, machining errors occur due to tool deflection based on cutting forces. With this product, it becomes possible to evaluate the amount of tool deflection and assess the relationship with machining errors, allowing for the consideration of various machining plans. 【Consideration Items】 ■ Tool diameter ■ Axial depth of cut ■ Number of flutes ■ Radial depth of cut *For more details, please refer to the PDF materials or feel free to contact us.

This is a case where the tool deflection was evaluated from the cutting force assessed in the cutting simulation of the "Production Module." By applying the analysis results from AdvantEdge to the geometric simulation on the CAD/CAM model, the cutting force during machining was calculated. The cutting force, which is the analysis result, can also be utilized for strain deformation analysis during machining. Additionally, in a case where mesh generation was performed on the shape of the workpiece during machining, and strain deformation analysis due to cutting force was conducted, it was found that the strain deformation on the workpiece side is not determined solely by the cutting force, but that the contribution of the rigidity on the workpiece side is also significant. 【Tool Path Analysis】 ■ Operation equivalent to CAM using GUI ■ Supports importing chatter stability limit curve diagrams ■ Navigator function ・Tool position ・Target NC line *For more details, please refer to the PDF document or feel free to contact us.

In the 'Production Module' that evaluates cutting loads on CAD/CAM models, it is possible to conduct necessary considerations for creating optimal machining processes through cutting simulations. We will introduce examples of considering tool changes through cutting simulations. While improvements aimed at increasing productivity are demanded daily, it is difficult to stop the manufacturing process for testing. However, this product contributes to reducing machining time through tool changes. [Issues] - In addition to diverse geometries of tool paths, it is common for machining processes to include multiple operations such as face milling and drilling. - While improvements aimed at increasing productivity are demanded daily, it is difficult to stop the manufacturing process for testing. *For more details, please refer to the PDF materials or feel free to contact us.

NC data for lathe machining can also be evaluated for cutting simulation using the 'Production Module.' In lathe machining, while the S value remains constant, the cutting speed varies depending on the diameter of the workpiece. However, the analysis with this product also evaluates the impact of cutting speed. Additionally, accurate workpiece shape data is required for the analysis, but since it is modeled in two-dimensional cross-section, creating workpiece shape data is easy. [Reasons why analyzing NC lathe codes is effective] ■ Suitable for optimizing load → The analysis also evaluates the impact of cutting speed. ■ Easy to execute the analysis → Since it is modeled in two-dimensional cross-section, creating workpiece shape data is easy. *For more details, please refer to the PDF materials or feel free to contact us.

In "AdvantEdge FEM," the use of parallel computing options allows for a speedup in computation time. By accelerating computation time, it becomes possible to analyze large-scale models that were previously difficult to simulate in cutting simulations. We also present examples of analysis results used in other analysis software (LS-DYNA, Abaqus). [Case Overview] ■ Burr evaluation during intersecting hole machining ■ Hole machining on inclined surfaces ■ Analysis of deep hole machining ■ Chip evaluation analysis *For more details, please refer to the PDF materials or feel free to contact us.

In "AdvantEdge FEM," it is possible to evaluate parameters that are difficult to measure, such as tool deflection, through cutting simulation. We will introduce a case study of a cutting simulation experiment where tool deflection varies due to machining factors. There were challenges associated with tool deflection, such as "degradation of shape accuracy," "the occurrence of chatter," and "difficulty in measuring deflection." With our product, you can quantitatively understand the factors that influence tool deflection. Please feel free to contact us when needed. [Challenges due to tool deflection] ■ Degradation of shape accuracy ■ Occurrence of chatter ■ Difficulty in measuring deflection *For more details, please refer to the PDF document or feel free to contact us.

This is a case study on cutting simulation analysis of titanium alloy milling using "AdvantEdge FEM." In addition to tool temperature and cutting resistance values, the chip shape changes complexly according to the amount of material removed, leading to a high demand for analysis such as chip shape control. Therefore, we conducted the analysis using our product. It was found that with double the cutting speed, the spindle power also doubled, and the cutting temperature increased by 200°C. 【Cutting of Ti alloy (Ti-6Al-4V)】 ■ Excellent high-temperature strength → A large amount of work is required for cutting ■ High work hardening rate → A large amount of energy is required to generate chips ■ Low thermal conductivity → Heat tends to accumulate in the tool ■ Reactivity → High chemical affinity at elevated temperatures *For more details, please refer to the PDF document or feel free to contact us.

The shape of chips during cutting can be evaluated using the cutting simulation of "AdvantEdge FEM." In this case, the changes in the 3D chip shape when cutting aluminum alloy were evaluated through simulation. It was found that the chip curl diameter and thickness changed significantly with only the adjustment of the rake angle. Additionally, advanced cutting simulation cases using CAD data of tool shapes are also included. 【Evaluation of Aluminum Alloy Chips】 <2D Milling, 100φ, 2000RPM, 0.05mm/tooth> ■ Rake Angle: -13 ■ Rake Angle: 0 ■ Rake Angle: 13 *For more details, please refer to the PDF document or feel free to contact us.
