First of all let me state that I presently don't even own a CNC machine. It will be about three more months till I have the funds to buy my first CNC Mill.
In the mean time I've been (past several months) working strictly on CNC Simulators just to try to get up to speed.
For training purposes I started using the free "G-Simple" program offered over the internet. For the most part, I think I have it pretty well figured out except for some it's more elaborate nuances.
After I make my drawings and converting them to G-Code, I then transfer the files over to a more detailed Simulator just to confirm that my G-Code works in Simulator programs other than the Rudimentary-Simulator that comes with the G-Simple program.(CNCesPRO)
Lastly, I'll transfer that same G-Code over to the Mach3 program because it's the Controller program I intend to use with whatever CNC Mill I end up buying.
Here's my Questions:
I'm attempting to make a cast lead bullet mold. Drawing it up is easy enough. Creating the basic G-Code to machine my parts is also fairly simple.
The point where I start running into problems is in trying to figure out how to go about milling my bullet cavities with my "Cherry."
With my two bullet mold halves side by side I can pre-drill my bullet cavities to pretty close (dimensionally) to where I need them to be but, after that I'm not sure if I should finish these same cavities as G-Code written for a vertical "Pocket" or, if I should separate the two mold halves and machine the bullet cavities one half at a time.
Ideally I'd like to pre-drill my bullet cavities and then, with a smaller diameter "Cherry/Reamer," insert it down into the center of my pre-drilled holes and program it to Ream-outward until I get the dimensions I'm wanting.
Unfortunately for me, the G-Simple program will not recognize tools such as "Cherry/Reamers." And my attempt at using a substitute tool such as an end mill or drill -just so I can generate the G-Code- brings up warning messages.
I said all of this just to ask, how would some of you more experienced G-Coders go about reaming out the final dimensions of these bullet cavities?
I've included an image of one of the bullet molds I eventually hope to make up. My ramblings sometimes don't make any sense unless you have a visual idea of what I'm trying to accomplish.
Thanks in advance to any who can offer suggestions.
