Question: Does VoluMill avoid burying the tool by shaving material away with many light cuts?
No. Unlike other toolpath strategies, VoluMill intelligently leverages many different techniques throughout a single operation in order to generate the best cycle times and best tool life for your needs.
If you choose, VoluMill can enforce a side milling strategy that prevents the tool from ever moving farther than the programmed stepover from the previous cut. This option is particularly useful in hard metals, where it may be undesirable to fully bury the tool. Although some looping motion will occur, the looping occurs only when absolutely necessary; unlike many other strategies, a VoluMill toolpath is designed to maximize the amount of long, smooth, racetrack-like cutting.
For softer materials such as 6061 aluminum, or light axial depths of cut with large stepovers, you may choose to allow slot milling as well as side milling. If so, VoluMill will automatically choose side milling or slot milling on a case-by-case basis during toolpath generation in order to minimize the cycle time. When slot milling occurs, VoluMill will slow down the cutting feedrate and/or reduce the axial depth of cut to keep the material removal rate constant. The user can override this behavior for even greater control.
The upshot is that regardless of your material, machine, tooling, or part shape, VoluMill can give you better cycle times and tool life than you ever thought possible.
