MachineWorks Releases Cutting Tool Engagement Demonstrator

This cutting tool engagement demonstrator available for cutting force analysis of CAM toolpaths.

SHEFFIELD, UK, Oct 30, 2024 – MachineWorks Ltd has announced the availability of a new cutting tool engagement demonstrator for cutting force analysis of CAM toolpaths.

Understanding the forces that operate on a machine tool during machining is an important way to model and predict important physical behaviours, such as vibration, chatter, tool wear, machine wear and their combined effects on surface quality, workpiece deformation and springback.

Predicting the forces acting on the cutting tool as a CAM toolpath is executed is also important for feed rate optimization – understanding where it is safe for the tool to move faster, or indeed where a lower feed rate will produce a more desirable result.


An accurate in-process stock model is an important part of computing and understanding the cutting forces operating on the tool as it engages with the stock.

Based on WPF and MachineWorks’ C# wrappers, the new MachineWorks’ demonstrator is provided as unsupported example code. It demonstrates using the new end-position engagement surface API from MachineWorks 8.6 to extract accurate in-process stock information for cutting force analysis calculations.
