An example G-code for Sinumerik

[sion]

Hello, Can someone post an example of a simple G-code for a Sinumerik (840D)?
Thanks

[tfisher]

here is a simple program used on a boring bar.

T5 M6 ;TOOL CHANGE
T6 ; PRE SELECT TOOL
D1 G54 G90 G95 S500 F.012 M3
TRANS Z-10 W10
GO Z0
X0 Y0 W5 ;position cutter in middle of hole
W-1 ;position 1 inch in to hole in part
G1 X2 G41
G3 I-2 ; cut 4 inch diameter
G0 X0 G40 ;rapid back to center and turn off cutter comp
W10 ;rapid saddle out 10 inches
TRANS
M30 ; end program

if you need more examples or have something specific you need done i could probably help. i have lots of programming experience with this and have written lots of macro's for various operations.

Thanks for posting the code,
This is bit complex for me. Could you please post as simple as

Move in direction of X 10mm
Move in direction of Y 10mm

I actually want to see the exact format(headers etc) of the code for Sinumerik .
thanks

[tfisher]

the first few lines of the program are loading the tool and getting the offset designated.
D1 TURNS ON TOOL LENGTH
G54 OFFSET I AM USING
G90 DESIGNATES ABSOLUTE COORDINATES
G95 IS INCHES PER REV.
S IS RPM
F IS FEED IN IPR

to move the actual axis all you need to program is the following.

G0 X10 ;MOVE X ABSOLUTE 10MM FROM 0 IN RAPID G1 WOULD BE FEED
Y10 ;MOVE Y 10MM UP FROM 0

hope this is what you are looking for if not let me know. anything written after a semicolon in the program will not be read. by the control

I think the GO should be G0 (difference between the word "GO" and "G ZERO")

Sion,
I will be glad to help you, only wish to know which kind of machine you have (turning or milling) and how many axes it have.

Down you can see an example of my code for Waldrich Coburg Multitech portal milling machine, but don't be afraid it is not so complicated as seems.

I can try to find complete Programming manual in PDF format, if you need it.

This is a sample from a Siemens 840D (NT) on a toolgrinder (5-axis). The code in red is prob. machine specific (sub programs), you can try as is, If it alarms out, just delete the code in red.

A few things you should know (840D) runs 2 folders, the Main program & the Sub programs, each machine part can only have a single main program ( %_N_MAIN_MPF ) the "MPF" defines the Main program. You can do this from the "Program" softkey (Menu Select/Program).

You can also run the same code from MDI:

G0 X0.0
G0 Y0.0
G01 X-10.0 F=50.0
G01 Y-10.0 F=50.0
G0 X0.0
G0 Y0.0

What machine are you running , & what specific cnc Control, 840D, 840Di,810D ?

Thanks a lot. that was all I need.

@Tale, I use 3 axis milling machine for precesion cutting operaions.
Yes a turorial would also be a great
best wishes

Sion,
I find Sinumerik 840D Programming manual in PDF and I can send it to you,
just need your e-mail address!

[tfisher]

what kind of machining are you trying to do with the canned cycles? i'm not too familiar with the lathe cycles but i have looked at them and they are similiar to the milling ones.

Hi

Thanks for your reply and this is for poreba cnc horizontal lathe.it has all work offsets like g54-g57.thks
