Pencil milling is used to clean up corners or fillets of a part. Pencil milling operations automatically detect corners less than or equal to the specified radius (including sharp corners) and then create a single toolpath to clean out these corners.
Applications of pencil milling include:
- Finishing fillets in a part with a single toolpath.
- Cleaning up sharp concave corners.
- Pre-relieving corners before high-speed finishing the part with a small tool.
- Roughing fillets by using the Finish allowance.
The first step is to determine the regions that contain the corners.
Depending on the number of surfaces in the model, this step may take some time.
After the regions are detected, a single toolpath is created that cleans out the corners regardless of the number of surfaces contained in the region.
