Hello,
I did similar projects before in powermill 2017. you can find one of them at my portfolio: https://www.freelancer.com/u/bordbar
I can provide milling animations, cnc codes (G codes and M codes) in .tap format for roughing and finishing milling process, End mill tools with all the information about cut length and diameter, shank length and shank diameter (I will show End mill tool in a catalog). I will tell you the end mill tool first position at the beginning of milling process and will specify the block dimensions. I can write cnc codes for a 3 axis milling machine.
Send me the parts technical drawings and let me check them, I need to check the parts first.
Send me a message and then we will discuss about the project.
I look forward to hear from you.
Best Regards
