Hey ppl,
First of all, Hi to all CNC'ers out there. Im kinda new to the CNC scene and trying to learn some stuff. If you guyz can help me out and kinda guide me, I'll be really grateful.
I got this small bridgeport in my hand, It is an old machine and mostly disassembled. Its not a full-size bridgeport and its not a tabletop, its the one in-between. Its got its own cast base, but has a 18 by 6 table, not bad really. So, I want to convert this machine into a 3 axis CNC, with possible auto-tool changing ability and a 4th axis rotary table later on.
Allright, so this is what I want to do so far;
- I want to use servo motors instead of steppers, they seem to be prefered more so than steppers in terms of efficiency and quality.
- I want to use this program called OneCNC XP. I have been looking into programs for a while and it seems that this program is user-friendly and has similarities to Soldiworks (which I am pretty good with). If any one has experience with other programs of the kind, please let me know.
- I want to be able to machine cold-rolled steel with this CNC, not only soft metals like aluminum etc.
Here is where I need help ATM;
- I got no idea on what type of servo I should be looking for; DC, AC, PLL...what kinda amps, rpms (I know I will need slower speeds maybe for steel), torque and such.
- I have very little understanding of drivers, signal amplifiers and controllers and which type and what I should be looking for.
- I have very little understanding of G code. For example, would I need another software that converts what oneCNC XP gives me into G Code or how would this work?
- I have some idea on how to convert the ACME screws on the mill to ballscrew but I would be glad for further advice.
- I got no idea on how to hook-up the mill so I can adjust rpm automatically instead of manually.
this is what I can think of right now, If you guyz can suggest ideas or directions, ill be really happy.
Thx,
