RE: CNC programming
RE: CNC programming
I know only EIA code
I worked with Picopath Numerical Controler
for milling and flame cutting machine.
I need to lern G code in order to get a job
as a CNC programming

RE: CNC programming
The files are in PDF format. u need an acrobat reader/plugin.

also visit and go through these sites
http://www.cncci.com (must visit site)
http://www.teachcnc.com/training/index.html
http://www.teachcnc.com/gcodelist.html (for G-code explanation)

Good luck for ur job
RE: CNC programming
G code programming is really simple if you're good with math.
There are only a few basic commands, and there is an easy way to remember them. This was INTENTIONAL when the code was developed!!!
G90 Absolute positioning (The zero looks like a bulls eye..)
G91 Incremental positioning (the "1" looks like an "I")
Absolute - "go to the intersection of 5th and main streets"
Incremental - "go 3 blocks, then turn right, then go 2 more blocks..."
G0 (G00) Rapid positioning (it looks like the word "GO"!)
G1 (G01) Linear interpolation - (the "1" looks like an "L")
G2 (G02) Circular interp. - (direction is the same as the way you start to write the "2"...)
G3 (G03) Circular interp the other way! Anti-clockwise
Each machine may be a little different about how you tell it about where the center of the arc is etc.
M0 - stop
M1 - Optional stop (no tricks here...)
M2 - tape rewind or end of program
M3 - spindle on clockwise (always looking down the spindle axis)
M4 - spindle counter clockwise (requires left hand cutters)
M5 - spindle stop
M6 - tool change usually
M7 or M8 turn on coolant (mist or flood)- varies with machine
M9 turn off all coolants
etc..
I have to go, but I hope this helped
RE: CNC programming
thanks for ur concerns.
The request was made by imbmd.
I just gave some suggestions.
Thanx,
ramu
RE: CNC programming
I am adesign engineer who owns a LeBlond 3-axis CNC mill, I do all my programming in Surfcam, The post processor should if (configured correctly)take care of all the G and M codes. I don't think you need to do any programming training (learning what the G and M codes mean)if you use a software package to write G code. I use Surfcam for even the simplest programming as its just plain faster. If you don't have access to a PC machining programm then you will be limted to the cpmplexity of parts you can write programs for.
If I have a problem with the post-processor outputting bad G code (especially with drilling, tapping, reaming cycles etc) I just get my wife who is a much better CNC driver than I am.
All the G and M codes I have learnt and become familier with is thru de-bugging programs
