Part distortion and tool deflection are available as an upgrade to Third Wave System’s Production Module CAE software, which is designed to provide a comprehensive solution for toolpath analysis and optimization. With the upgrade, Production Module users will be able to analyze legacy and new machining strategies with consideration not only for tool performance and production times, but also for the dimensional accuracy of final parts. With the ability to simulate, analyze and visualize multiple part geometries and their impact on distortion, Production Module may also be used earlier in the product design cycle by engineers looking to design products for future manufacturability.
Instead of making machining improvements based on trial-and-error tests, or sending parts out for secondary operations after machining, manufacturers can identify machining parameters to optimize part quality in minutes, the company says.
The software reads five-axis APT and G codes, permits importing of STEP and STL files, incorporates a database of workpiece bulk stresses, and automatically generates a thin-wall mesh. It automatically models factors such as cutting force distribution along the flute length, instantaneous cutting forces, and changes in cross-sectional moments of inertia along a tapered tool.
