CAM

Generating Tool Path

1. New Corner Finish Operation

The Corner Finish operation is used to clear corners as a follow up to other Quick Mill

operations.

What is its character

1. Composite Strategy

This operation should analyze the trace curves of the corners, then produce

stitches on the steep area and along passes (contour passes) on the shallow areas (see

below), according to user controlled threshold angle.

2. Constant Cutter Load

In order to keep a constant cutter load (thus get better surface quality) and avoid

gouges, the sequence of cuts in the contour passes (in shallow region) should be

ordered as follows.

26 / 34

3. Support to clean both sharp corners and corners with fillet

No matter in sharp corners or corners with fillet, we can detect rest area by

reference tool and create tool path with composite strategy settings.

27 / 34

How to use

1． Insert the new operation

You can find Corner Finish operation in:

Ribbon – 3X Quick Mill – Finish

CAM Manager – Operations(Right-Click Menu) – Insert Operation – Quick

Mill

2． Meet its private parameters

See “Cutting Steps” and “Path Setting” in the operation form, private

parameters includes:

1) Two Path Patterns: Along and Across

2) Two Step Settings of Cutting: Flat Region and Steep Rgion

3) Two Region Detect Patterns: Number of Cuts and Reference Tool

4) Others:

Steep Angle: Define the steep region more than the angle.

Cut Regions: Choose the region to machine.

Cut Order: Machining sequence for two types of regions.

Overlap: The distance over the reference tools.

Cutting Steps Path Setting

3． What it needs

There are two “Path Pattern” in Corner Finish operation.

1) “Number of Cuts” pattern: Select a tool for Corner Finish and the range of cut

region is determined by “Number of Cuts” parameters setting.

2) “Reference Tool” pattern: Create a tool to machine and a tool to be referred,

28 / 34

and the range of cut region is determined by Reference Tool.

4． Tool path of sample case

2. Optimize Cut Order of Sub-regions in Roughing

Get the sub-regions in the same region after offsetting and order these sub-regions

to get an optimized cut order which will decrease unnecessary tool lift.

1) Keep the order rule for each region and sub-region, define the coordinate origin as

the start point of the first region, and the next region is based on the end point of

the tool path in previous region

2) The minimum distance is calculated between curves instead of start points

3) Fix revert region order issue to make sure the minimum distance

4) About Offset 2D, adjust the lead out point of tool path to get more closed to next

region and get shorter link, especially some narrow and long regions.
