Ok so here is what I am sure is probably two dumb beginners questions.
I am making a part out of .500 inch hex stock in 1018 steel.
My question is about depth of cut and width of cut when it comes to milling a circular boss.... As I understand it, during a helix cut my step down is going to be the specified amount in my CAM softeare for each revolution of the cutter around the part. IE, my programmed step down is .025 and it will take one full revolution of the cutter around the part OD to complete. Is this correct?
Also what I am unsure of is what number do I use as my width of cut in GWizard. Im being confused because it is a round cutter with hex part stock. Should my cut width be represented by the measurement of the maximium thickness of the hex to the rough OD of my part (.070) Or should my cut width be represented as distance between the two outer most points on the cutter that are in conact with the stock material (.180)? See picture for visual explanation.
So I guess my overall questions are these.
1. Am I correct in that my step down of .025 happens once for every revolution of the tool around the outside of the part?
2. In this example which measurement should be in the "Cut Width" box in GWizard.
Any help and insight will be greatly appreciated.
