The full drilling program will now look like this:. It will repeat this pecking process until the final depth is reached. This means the drill will retract to clear the chips after the specified Q value has been reached. The Z value has been changed to the depth the drill needs to go and a Q value has been added to the line. Now we have applied the spot drill cycle all we have to do is copy and paste the program and change the G81 canned cycle to a G83 peck drilling cycle, changing the Z depth to how deep the drill needs to go. It will drill there first and then continue with the remaining two positions. S2000 M03” you can see that the machine was initially positioned at the first hole.

If you look at the G code line “G00 G54 X.5 Y1. This is because the machine will drill its first hole at the position it is already at. You may have noticed that there are only 2 positions after the G81 command even though we need to drill 3 holes. So the full program will look like this:. So on the next lines you only have to specify where else you need to apply that drilling cycle and the machine will continue drilling at the listed positions. The G81 canned cycle is a modal command, this means it will stay active until cancelled. The F value is the feed rate in inches per minute. The Z value specifies the depth to go to, the R value specifies at what Z height to start moving at the feed rate. We can use a G81 drilling cycle for this :. I am going to program a spot drill cycle first, prior to a peck drilling cycle with a drill bit. All we need to do is add a drilling cycle with 3 locations in between the header and footer. Now we can move on and do a simple drilling program using the header and footer.įrom the drawing above we can see there are 3 holes that need drilling. You can copy and paste these into a text editor for the basis of a program template. Here are the header and footer together without the explanations in brackets. M30 (finish program and rewind to the beginning and stop) G90 (re-establish absolute programming mode) (Tool length offset command and Z pre-position line) Cnc program Footer T1 M06 (Tool call and tool change commands) G17 G20 G40 G49 G80 G90 (safety line establishing important G codes) I keep a selection of basic programs that I can copy and edit, it makes the process of writing a new program really quick. You can use these for every program you write, just copy and paste whenever you need to write a new program. In my article “ G28 G code demystified” I explain program headers and footers.

It is definitely an advantage to know how to read and write G code as it will make improving your cnc programs so much quicker and easier. This will depend on how much practice you have had and whether you even enjoy writing them. I say “basic” because you will need to decide when it will be easier or quicker to create a Cnc Project in a cad/cam program than it will be to write your own cnc G code. A hobbyist Cnc operator should not have any difficulty in learning how to write simple G code programs. Basic cnc programs are not too difficult to do.
