Helical Milling

This option enables you to enhance the productivity of profile machining by avoiding lead in/out movements at each Z-level and unnecessary rapid movements.
With this option, the tool performs the spiral movements around the geometry with the continuous lowering along Z-axis. For each turn around the geometry, the tool moves downward along the Z-axis according to the step down value. When the Profile depth is reached by the spiral movements, SolidCAM performs the last cut with the constant Z movement at the Profile depth level.

Data

This button enables you to define additional parameters of the helical pass.

Helical cut from

Using this option, you can choose the direction of the helical pass: From top to bottom or From bottom to top.

Strategy

You can also choose not to perform the last cut with the constant Z movement at the Profile depth level. To do this, clear the check box near the Generate last flat step option.

The helical movement cannot be performed, when finishing is done in one cutting pass (Step down is set to 0).
