G1 with R (Fanuc 0-MC)

[padobranac]

I have one machine which appects that (G1 R<number>) and other one doesn't accept. Actually no alarm pops out but it makes sharp corner without radius.

Both machines have Fanuc 0-MC.

I have found some old thread with same problem but it hadn't been solved.

Post your part program

[padobranac]

Here it is

G0 X9.50 Y-27.40
G0 Z-9
G1 X-212.69 F500
G2 Y6.20 R17.20
G1 X6.20 R20
G1 Y-29.55

But, there should not be problem in program, because 100% same program on one machine works and on other doesn't.

Looks like a decimal point problem. Have you tried R20. in that block?

I would compare parameter 0015 bit 7 and 0016 bit 3 on both machines. Make the one that doesn't work the same as the one that does.

G01 is the Linear interpolation only try G02 in place of G01

[padobranac]

0015#7 = 1 on both machines (If a decimal point is omitted, the selected unit is the least input increment / mm, inch, deg, and sec.)

0016#3 = 0 on both machines (Decimal point input or display is used / is not used)

I knew that it is not problem with decimal point because I know that machine interprets numbers without decimal point as milimeters.

Any other ideas?
Maybe there is a parameter to enable this, but it might be 900's parameters which I don't have in my param. book???

well this is waaaaaaaaaaaaay too late but i think you need to put "," before so it goes lie=ke this

G0 X9.50 Y-27.40
G0 Z-9
G1 X-212.69 F500
G2 Y6.20 R17.20
G1 X6.20 ,R20 <-----
G1 Y-29.55

just for info if someone else had the same problem

Look for Parameter for Circle intrpolation
One is for an R value and the Other will be for I/J/K
