8. Computer controlled machining

• Select the tool - i use the 8mm flat end mill. Speed choose 500, feed 5000. Cutting depth -17.1(As the thickness of the material i use is 16.8mm).

• The cutting logic should be cutting the inner parts first and then the outer - Otherwise if cutting the outer parts first then it will be not easy to make the board stable to cut the inner parts.

• As the diameter of the drill i will be using is 8mm, so i have to make 8mm dog bones.
