Continue Rest Machining between setups is a way to transfer stock from one setup to use on another setup.

Select the Continue Rest Machining checkbox. Click OK. The stock from the previous setup transfers to this setup.

Activity 5 summary In this activity you duplicated the 3D Adaptive Clearing roughing operation, selected a library tool, reduced the Rest Machining parameters, set the cut stepover, step depth and stock to leave.

The purpose of Rest Machining is to remove the remaining stock from a previously cut part.

Watch this video to see a rest machining example that demonstrates using the Detection Limit and machining with Multiple Depths.

Using the Rest machining toolpath option, you will learn how to reduce the left over material with progressively smaller tools.

Manufacture workspace > Milling > 3D > Adaptive Clearing > Geometry > Rest Machining > Reduce Air Cutting Air cutting occurs when a tool performs a cutting move but does not engage with any material.

To begin, a 3D Adaptive Clearing toolpath is generated to machine the top side of the part: The part is then turned around in a second setup to machine the underside with rest machining : The images below shows the impact of reducing the air cutting moves on the 3D Pocket toolpath: Reduce Air Cutting OFF Reduce Air Cutting ON Excess cutting moves Efficient cutting moves Machining time = 28:10 Machining time = 15:57

Rest Machining enables you to specify the amount of stock to leave on the part between passes.

Offset the toolpath from the boundaries created by the slope and/or rest material detection. When using slope confinement and/or rest machining for a Scallop operation, you can use the Machine Areas Using Boundaries setting on the Geometry tab to start offsetting the toolpath from the boundaries created by the slope and/or rest material detection.

Note: When using rest machining , the tool you use in this operation should generally be smaller than the tool used in previous operations.

In this tutorial, before post-processing the toolpaths, you machined the part using the following methods: Roughing with adaptive clearing Rest roughing with pocket Contour machining Scallop machining Scallop Horizontal Pencil milling Collapsed pencil Post-processing Before machining the part (left).

Gouge checking occurs for the tip of the tool but not the rest of the insert or the holder geometry.

I edit to heights needed, shut off rest , and all fine. How is rest machining used?

This is useful if you have operations that have already been run on the machine , and want to do rest machining from these operations while accommodating changes to the model.
