Roughing Reworking

The roughing consists in getting off the maximum of material to be the closest possible to the final shape before finishing stage. GO2cam applies automatically on a solid a pocket cycle with Z successive increments and remaining material management.

Key Points

The roughing/reworking cycle does not enable a constant stock allowance on the whole part. It has to be completed by a semi-finishing cycle by Z increment or by sweeping if you want a constant material cutting in finishing stage.
To get closer to this result, we can decrease the increment value. This solution is good only if the machine is able to support high feedrates (HSM). For more conventional machines, we will prefer a list of operations starting with great diameter miling cutters to rough the part, and progressively come to the diameter close to the necessary value to get the final part.
When the rest material is minimum, it will be better to program a Z level finishing cycle than a roughing/reworking to save much calculation time.
