A usable CNC program or CAM file is created around the process of getting from “Point A” to “Point B.”

Point A is the current stock size and material.

Point B is the finished dimensions and print specs.

To get from “Point A” to “Point B” the machining processes have to be properly planned.

What machines will be used?

What cutting tools will be used?

How will you hold the part in order to remove the material?

Stock Size 1.5″ x 6″ Long
