A few more tips!
Hello,
Here are a few more basics. I am a Mazak, Haas and okuma guy, but this is some universal stuff!
Get to know cutter comp, G41, I.D., G42, O.D., engage it with a small perpendicular move in G1 and it will call up your tool nose radius from your offset page, usually the second "01" in T0101, it is the only way to get burr free parts unless you want to program in a pile of radius callups. Turn it off with a G41, again with a small perpendicular move in feed mode.
This is a description of a tool change and a finish pass, this is "NOT" a program! A proper program start will come from the next guy that wants to "school" you, watch these guys even shred this stuff!
G28X0Z0 (HOME FOR TOOL CHANGE OR YOU MIGHT PICK YOUR OWN LOCATION, on my Mazaks we use G28U0W0)
M01 (op stop for first run)
(.016 RAD FINISH, O.D.)
T0101G96S900M3M8 (T1, constant feed, spindle clockwise, coolant on)
G0X.5Z.1
G1G42Z0F.005
X1.R.015
Z-.5R.06
X1.2R.015
Z-.8
X1.3G40F.02M9 (G1 is still engaged, "modal" but I turned up the feed cutting air, coolant off)
G0G28X0Z0 (RETURN TO MACHINE HOME)
Most of your feed and canned cycles are "modal" and in most cases cancled by the next command. If you peck drill a hole, G83, and your line is a different Z or X cord. it will drill again there, G02 and G03, same deal.
Rules, no excetions!
1. Run program or program edits in graphics before you even think about making the machine move, paticular attention to rapids to tool change position. If it looks funky, you can run the part to prove how stupid you really are, been there, done that!
2. First run, put in "single block", rapids at 10%. Turn on op stop and make sure you have programed in M01 after G28 or your home position.
3. As tool approaches part, feed hold machine, check position, X and Z, make sure it looks right.
4. Look at "diatance to go", you might have this you might not.
5. Turn off "single block", stopping tools in the cut is a really bad idea!
Failure to follow these procedures will could lead to your termanition on the first occurance!
But being the shop owner we can be much more lenient, your machine may be "tacoed" on the first occurance!
Good luck!
