I see a beat up looking machine around me for sale, praying that it works. I am thinking I will need to check to see that it tool changes smoothly first. But I also want to program or MDI ( whatever is fastest) it to do a Circle in aluminum using a 1/2" end mill. I am thinking would be quickest to touch the mill to X Y and Z. Call Z zero and Move mill to center of workpiece and set that to say G54. I don't have patience to fuss with tool offsets when in some one else's shop. Now the big question is what is the rest of my code to do a few things I am interested in doing.
A.) I am not too worried about this cause it will be easy part. I need to rapid out of G54 say about 3" and then return and see that all went back to same position. I'll be using a mag base indicator. 1X for the X axis 1X for the Y axis and Z axis can be done with some shim stock and top of workpiece.
B.) Regarding G02 and G03 my memory not too well on how to write those. I need to Mill a circle on the outside of this aluminum stock say 1.5" diam anybody can write a G02 that will give me that without using a G42. For example just program a 1" radius instead of .75" radius ( .25" for tool radius)
C.) finally would like to mill a pocket on the inside of the stock say about .875" diam to see how it handles that. Probably a G3 and G41 just don't remember all the details.
D.)Anything else you guys suggest I check?
Been a long time since I wrote any Gcode and never programmed a VMC ( tool changers and stuff) before.
On a side note,
E.) Can this thing be moved with skates and then loaded on to a flat bed tow truck for delivery without being risky? Not interested in paying a rigger more than I am paying for the machine.
Thanks everyone.
