When Are the Different Feedrates Used?

HSMWorks has a set of different feed rates that can be defined on each tool. This list describes when the different feedrates are used:

Cutting feedrate

The primary feedrate used when removing material.

Colored blue in preview and simulation.

Lead-in (entry) feedrate

For milling strategies, this is the feedrate used when engaging the material from a linking move. In drilling, this is used used for the plunge - and hence cutting - movement.

Colored green.

Lead-out (exit) feedrate

For milling strategies, this is used when leaving the material for a linking move.

Also colored green.

Ramp feedrate

The feedrate used when entering the material with a helical ramp.

Colored green.

Plunge feedrate

Used for vertical movements into the material. These only occur if Plunge has been selected as the ramp type.

Colored red.

Yellow toolpaths in preview and simulation indicate rapid movements and are output as G0, FMAX or equivalent - depending on the post.

In certain situations, it may be preferred not to use rapid movements, and in such cases the rapid movements can be changed by changing the High Feed Mode in the Filtering group on the operation property page:
