Definition of processing at rest

Inevitably, when it comes to machining parts, some features may require multiple tools to work quickly and accurately. Remnant machining gives the programmer the opportunity to use a large tool to remove a mass of material by generating a second operation with a smaller tool that removes the remaining material.

Rest

For this example, a part was partially programmed, but some material remained in place. Replacing the tool with a smaller diameter will still produce the desired result, but at the cost of a long cycle time. To continue machining a machining where a tool has been interrupted, the remainder machining will be the best option.

Configuring the milling part

The remaining machining will be applied to a second rough milling operation. In the cam operation tree, right-click the desired mill part setting and add a rough milling operation. This new rough milling operation will be linked to the original feature being machined.

Once the second rough milling operation has been created, edit the new feature definition and proceed to the tool crib tab under the tool tab. Use the on-screen graphics to determine the correct size end mill that will remove the remaining material.

Once the correct size tool has been selected, proceed to the Roughing tab where an option box for machining the rest will appear. Under the machine, an option for WIP (Work in Progress) or Previous Remain will appear. From WIP it will give the opportunity to use to have control over which previous operations are used to calculate the desired material to be removed. Whereas the previous remnant will calculate the toolpath based on the remaining theoretical areas which have been calculated by the remaining generation option.
