Denford Software & Machines

HI,

I am a final year student at London South Bank University and for my final project I am working on a Denford Triac ATC(1989).

I am using the Denford Triac V2.4 (dos software) to create the cnc code and then send it to the machine via R232 cable.

The part I am working on is 98x70x29(mm.) I want to create a counterbore hole using a Circular Pocket cycle, G82. I have created the code and send it to the machine. When I run the program it stops at the G82 code and the error MOVE EXCEEDS MACHINE LIMITS comes up.
Also I have set the G55 offset (machine offset) using a touch probe at the bottom left corner. In other words the machine should run the cycle...

Here is the code:

[BILLET L98 W70 D29
[TOOLDEF T2 D6.6 L90
[TOOLDEF T1 D10 L60
N001 M06 T1
N002 M03 S1000
N003 G00 X0 Y0
N004 G00 X15 Y12.625
N005 G01 X15 Y12.625 Z1 FX80
N006 G82 R5.625 Z-9 C4 FX80 FZ80
N007 G80
N008 G81 R6 E8 N1 X68 FX80 FZ80
N009 G81 R6 E8 N1 X68 Y44.75 FX80 FZ80
N010 G81 R6 E8 N1 Y44.75 FX80 FZ80
N011 M05
N012 M00

Can anyone help me or suggest something?

Thanks for reading my post.

I've never really used the DOS stuff, so hopefully someone else can help / or test it out for you.

Does the program simulate OK ?
I thought the DOS software could be run offline, and programs tested with the graphic simulation ?

Not sure but...

N006 G82 R5.625 Z-9 C4 FX80 FZ80

Try Changing C4 to C1 or R5.625 to R10 to see if the old Triac may have a minimum arc radius it can work with (and these arc rads work out pretty small.)

Or try replacing the line with "G01 Z-9 FZ80" to see if it's the Z axis that's complaining

Although this is no help in solving CK's problem. The old Dos software does not accuratly 'simulate' what the triac can do as I found out this week as 'Triac 2.4' was telling me arcs were 'out of quadrant' but the programmed arcs ran fine on the Triac itself.
Just thought this might help in some way for anybody using the simulation?

THANKS A LOT for your comments guys!!!!

Yes, the simulation of the Triac V2.4.exe is not that good especially when using the ARC command as you said..

I will try to alter the code as you pointed out (Try Changing C4 to C1 or R5.625 to R10 ) but I tried replacing the line with G01 Z-9 FZ80 and it works fine....

For the next 3 weeks I will not have access to the lab at my uni due to easter holidays but when it opens I will try what you suggested and get back to you.

THANKS
