Tryed it with lollipop mill: roughing with flat mill: Toolpath with lolli: 0 result - the tool wont cut into material: Z steps from previous operations are 0.5 mm Settings: I think i have tryed literally everything to make it work, sadly with 0 results. I even tryed to use bigger tool for simulation, nothing happend.

Hello everyone, it has been some time since last i asked you about help. Now i have different problem to solve - Port milling part to mill: I have pre-drilled a hole: Now to my problem: - how do i tell to mastercam not to go behind a green line A - it starts machining like i want, but then skips in the depth causing many many collisions (don't mind my imaginary long tool) Results: Our school has edu version of X8, so if smn is willing to take a look directly at the toolpaths and my flawed settings, i would appretiate it. Even some pdf sample with "how to" settings would be nice. http://leteckaposta.cz/728409324

jlw - the tool was custom made by my friend, and cutting part was grinded from RADECO

Ofc nobody here, especially creator of this maquette, would never think about firing from it Thank you Allan, that is what i thought. - G01 Z-120.00 C90. F - yesterday i came up with an idea to set F equal to time needed for doing 120mm (in 1 min) and spindle speed equal to the curvature of the helix (0.3 per minute) I just didnt know, that i can write it in G code like u did. Edit: Yes it will be in the center.

My apollogies i forgot to mention that stock will be made of EN AW 6063-T66. So i doubt there could come to a damaging of bearings.

Actually it is educational user. This is for machining of some parts for colt 1911 - for a thesis.

Here are some images of what it looks like: http://www.imgup.cz/image/WiR http://www.imgup.cz/image/Wif http://www.imgup.cz/image/Wi2 http://www.imgup.cz/image/WiT How exactly would you draw a geometry of that tool? - an advice or any pdf describing it would be appreciated And about the hand coding - on the machine or in mastercam? - Iam kinda failing with comming up with an idea how to tell mastercam tool No. 1 G01 from z 0 to z -120 while do rotation of spindle 0.34*360° (0.34 was taken from solidworks - parametr of helix)

Well yes, you are right in that, but it should be doable on CNC lathe. Considering fact - a tool will do only 0.1 mm depth of cut and rotation will be <0;90>° on a 120mm length. If it wasn't helix groove, it would be easy - just a rough toolpath with 0 spindle speed. And ofc defining a tool - cutting (3x) edges to be more specific - from IGS.

Hello everyone, my friend would like to ask u about something. Thing is, he is trying to do an inner slotting in a gun's barrel - rifling. He made his own tool for that purpouse. Now for the question - how should he proceed in programming this task? How to import slotting tool? And how to tell mastercam - do this helix groove inside. - which toolpath should he chose? Thank you for your advices Best regards Azi
