G41/G42 on 8025TG

[Captdave]

I have her back up and running again everything seems to be working well. I have always used this machine for second ops and threading and have never had any luck getting the G41/G42 for TNR to work. If I have needed to compensate for it I just added the TNR to the desired radius and let it fly.

I'm sure its in the way I'm programming it (0r where) and the Fagor manual is written so poor that my simple little mind cant get around it.

If some one could please post a sample block of a program with the correct format that it would be helpful.

No one uses cutter comp while turning?

[dek]

go into tool offset table
r is for tool radius
f is for location code
location code is found in user manual
make sure you on a front loading toolpost or rear for the codes

[Captdave]

Yep did all that too!

[dek]

also the tool must be called up in the line with g41 or a previous line and dont for get to cancel with g40
i.e T1.1 F.01
G41 X10 Z0

[Captdave]

N200 G92 S2800 T08.08 M3
N210 G41 G96 S500
N210 X0 Z0
N220 G1 X-.625 F.004
N230 G39 R.070 X -.625 Z0
N240 X-.625 Z-1.00
N250 G2 R.050 X -1.205 Z -1.000
N260 X-1.205 Z-1.150
N270 G0 Z.100

Is this correct?? Tool tip 5 in register, cutting on the operator side M3

[dek]

if it is a front mounted toolpost the code is 3 . The code 5 would be for rear toolpost
also if front mounted toolpost you x should be +

[Captdave]

Its' a gang tool lathe so the tools can work on either side of the spindle by just turning them up side down. The example I gave was for a tool cutting on the front/operator side of the spindle.

My manual shows 5 for front/operator side and 3 for rear tools as copied from the manual below:

"• F3 would be an outside turning tool on X+ or a boring bar on X-"

"• F5 would be a boring bar on X+ or an outside turning tool on X-"

Is the rest of the code correct for use with TNRC?
