Hello ., I own a daewoo puma 230 msb with controller fanuc 18i, is there any G code for drilling in X axis with the live tooling or I have to program it in G01 ? I am looking for a G code like G81 or G83 but for the X axis , I have been trying G87 but I have an alarm G-code error Okk thank

G87 is X-axis drilling, G88 is X-axis tapping.

Please post the section of your program where the alarm occurs and the alarm number.

what is your control? Daewoo has it own control I don't think it has Fanuc..... I had never worked with Daewoo before, but one time I read their program manual and from what I remember, can cycle for Daewoo is difference then Fanuc, so check your manual.

According to his post, it's an 18i. Daewoo currently uses Fanuc controls, they used to put Mitsubishi on some of the machines. AFAIK, they never had their own control.

hi thanks for the help , Yes my controller is a FANUC 18i-t year around 2001
I have try G87 and dont work ,

my featurecam program the block like that

M33S2000G0G54G98:
G0X2.0Z-1.0:
G87U-0.200R0F5.0
G28U0W0

I have try change the U-0.200 by X-.200 and X .200 but always the same result , it says Improper G-code 010 , even when I just type G87 in mdi mode I end up with this I think its maybe a parameter that is wrong or this fanuc dont have the option of drilling in the X axis ,
ok if someone have an idea let me know thanks !

You might need a C-axis command in the G87 line. Also, a G00 in the G28 line.

This is a sample that came in the Daewoo MS200 we bought.

Not sure if I have a sample of the G87 used in one of my programs. I normaly use G1 as I seldom use a spot drill unless also tapping. Thus I feed very slowly until the drill point is into the material before kicking up the feedrate. Can't do that with a G87 cycle unless you want to run it twice.

M88= low pressure clamp, M89= high pressure clamp, M90 cancel clamp pressure on our lathes. Don't know if the M35s are necessary. I do know that we have to start the live tooling at S300, make a move & then kick RPM to desired level as the tool doesn't always catch and alarms out if started much faster.

EDIT: Not sure if the samples that were in the control upon purchase are 100% correct. I don't see an M90 to cancel the high pressure clamp.

What is the serial number of your machine?

hi philrace

can u try this?

G98 ;Feed per min
M33 S2000
G28 H0

M30

@dcoupar
can it be that G87 ist an Option and he do not have it?

[dcoupar]

That's why I asked for the serial number. AFAIK, if you get milling on a Puma, you get canned cycles.
