Hi

I would like to cut out a rectangle draft (abt 15deg) on a 15mm thick.

My procedure is as follows:
1. Relief the rectangle and draft the angle
2. Perform a cutout the material using endmill on a smaller vector
3. Perform a Z level roughing with the 2 vectors selected

The problem is that if I perform step 3 the tool path generated will try to finish the inner vector and this waste 50% of the time.
Is there a way to label the inner vector as a keep off area or other method to machine this rectangular draft?
Or any 3D cutout can follow the draft?


thank you

Offset the inner vector at least 1/2 of your roughing tool diameter and Select the outer vector and the new offset inner vector and use "Selected Vectors" in the Z roughing tool path, it will only rough out the area between the selected vectors.

You can save time if you only relief the draft angle, then do the cut out and Z Roughing, no need to relief the flat area as its already being done by the Z roughing.

Hi Phief thanks for the advice

I am using endmill of 6mm.
In this case with the rectangular draft vector and offset inner vector selected, the cutter have to cover about 10.3mm at the top. (refer to attached cross section view)


I guess there is no other better way out due to the material at the imaginary offset inner vector. The cutter had to move at least 2 times for each step of Z as I am using offset strategy

Thanks
