Recently, I bought an add-on to our CAM package as I wanted to do some porting on muzzle brakes that I wasn't able to do otherwise. Its the exact same software used to program intake and exhaust ports for CNC porting on cylinder heads.
It's pretty cool stuff to use. It sure makes this kind of work a whole lot easier to program and execute. This is a three op part. Prep the slug and let her buck, then throw it in the lathe and whack the slug off. The ports are a canted elipse that transitions to a square entrance that is symmetrical to the bore centerline. Were canted 15 degrees from perpendicular.
Material is 416R SS.
Thanks for lookin.
All done. Now we just spin the barrel to blend the shoulders.
I grabbed this scrap block of AL a few weeks ago to familiarize myself with how the software works. Modeled up a "pretend" combustion chamber and intake port, then threw it in the machine and tried it out. Pretty cool for a first attempt and just farting around.
ID bore honed on our Sunnen connecting rod hone and the outside fluffed up with scotchbrite.
