Clearance - Specifies the absolute height at which the tool can move freely in the XY plane without encountering any material or fixtures.
Retract - Specifies an incremental value, as measured from the Level. Retract is the height at which the tool begins its cycle.
Level - Specifies the absolute height at which the cycle is to start.
Safe Distance - Specifies the height above the next cutting pass the tool rapids down to before feeding down to the cutting depth. If you do not enter a value, the tool will feed all the way down to the cutting depth.
Relative Depth - Specifies an incremental depth. Move the entire toolpath along the Z-axis by the stated value.
Finish At - The Finish At parameter allows you to control the behaviour of the tool at the end of the milling cycle. Select one of these options:
Depth - The tool remains 'at depth' at the end of the last pass.
Clearance - The tool makes a rapid move to the Clearance plane from 'depth'.
Retract - The tool makes a rapid move to the Retract plane from 'depth'.
Maximum Height - Specifies an absolute height, above which toolpath sections are removed and connected by rapid link moves. If the toolpath is trimmed to the restriction heights, the tool rapids clear and moves to the next valid position. Any Approach moves generated by exceeding the Maximum Height are limited to Plunge, as the projection has already occurred and a ramp move cannot be de-gouged. This only applies if Cut Increment has not been specified.
Minimum Height - Specifies an absolute height, below which toolpath sections are flattened out.
