Milling with a Citizen C16

Hello !

I've got a big problem. Right now I'm trying to program a pocket on a Citizen C16 type IX.
I'm working with the live tool position number T11.

The size of the pocket is 6mm bright and 10mm long. The problem I have is this one. The brithness is right after the machining but the lenth and the raduis are wrong, to small why ?? The size of my tool is 3mm.

Do I still have to enter something under the tool data ??

Please help

Try this, OR add size of tool to the "R" on the tool data page (P=0)

Still not working

I tried both solutions and it's not working. If I had the R in the tool data page
I get an alarm and if I change the program with the dimension you gave the radius is still wrong.......

Why ??

This is weird. I used to mill on the Fanuc CNC and I never got any problems

What alarm did you get? What is the radius coming out as?

Alarm P153 !!

And I also tried to write 1.48 instat of 1.50 in my tool data !!

Well I think this CNC is not as powerfull as Fanuc for milling. What I don't get is why is the size 6mm bright ok but the radius 3.0 is to flat ?? The G42 seems to be fine the lenght and all the points too.......... Maybe the CNC cannot find the right point when the tool radius and the radius in the program are the same !!

Something is weird....

code

The code below worked in my C16IX. This control is just TOO smart to accept any possible error. I had to convert to inch for my machine which gave me the following when converted back. I did not cut I just ran it through the motions and solved the alarms.

(TDATA= R=1.4986 P=0)

Still searching !!

Thanks for your help but it's still not working on my machine. Maybe the soft of my CNC is different. I'm looking further ....
