CNC programming

Where can I find desbribed<br>G-code from CNC programming

 

[dandrews]

There are books (can't think of the name, it's still early) that have the ANSI G and M codes.&nbsp;&nbsp;The best reference is your machine's operations manual, because it will have all the standard G and M codes plus any proprietary codes.&nbsp;&nbsp;Every controler is different, which are you working with?&nbsp;&nbsp;I have worked with Mitsubishi, Fanuc and Charmiles; I maybe able to help.

thank you for ansewring me<br><br>I know only EIA code <br>I worked with Picopath Numerical Controler&nbsp;&nbsp;<br>for milling&nbsp;&nbsp;and flame cutting machine.<br><br>I need to lern G code in order to get a job<br>as a CNC programming<br><br>Mircea BALAN<br>Romania ,EUROPE<br><A HREF="mailto:bmd@fim.usv.ro">bmd@fim.usv.ro</A>

Visit this site for G & M codes mircea, u can find a table with titles.<br>The files are in PDF format. u need an acrobat reader/plugin.<br><br><A HREF="

Ramu,<br>G code programming is really simple if you're good with math.<br><br>There are only a few basic commands, and there is an easy way to remember them.&nbsp;&nbsp;This was INTENTIONAL when the code was developed!!!<br><br>G90 Absolute positioning (The zero looks like a bulls eye..)<br>G91 Incremental positioning (the &quot;1&quot; looks like an &quot;I&quot<br>Absolute - &quot;go to the intersection of 5th and main streets&quot;<br>Incremental - &quot;go 3 blocks, then turn right, then go 2 more blocks...&quot;<br><br>G0 (G00) Rapid positioning (it looks like the word &quot;GO&quot;!)<br>G1 (G01) Linear interpolation - (the &quot;1&quot; looks like an &quot;L&quot<br>G2 (G02) Circular interp.&nbsp;&nbsp;- (direction is the same as the way you start to write the &quot;2&quot;...)<br>G3 (G03) Circular interp the other way!&nbsp;&nbsp;Anti-clockwise<br><br>Each machine may be a little different about how you tell it about where the center of the arc is etc.<br><br>M0 - stop<br>M1 - Optional stop (no tricks here...)<br>M2 - tape rewind or end of program<br>M3 - spindle on clockwise (always looking down the spindle axis)<br>M4 - spindle counter clockwise (requires left hand cutters)<br>M5 - spindle stop<br>M6 - tool change usually<br>M7 or M8&nbsp;&nbsp;turn on coolant (mist or flood)- varies with machine<br>M9 turn off all coolants<br><br><br>etc..<br><br>I have to go, but I hope this helped<br>

Hi LTD,<br><br>thanks for ur concerns.<br><br>The request was made by imbmd.<br>I just gave some suggestions.<br><br>Thanx,<br>ramu

 

Although its worth knowing what all the G and M codes are, its not a show stopper if you are not that familier with them.<br>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.<br>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. <br>All the G and M codes I have learnt and become familier with is thru de-bugging programs<br>regards<br>Dave Cam<br><A HREF="
