probing Probing - RMP60

[AKL635D]

Probing - RMP60

1)  Trying to do probing  on DOOSAN NHP 5000  -HMC with B axis machine. Control Fanuc 31i - Model B

2) History -  we did only manual probe of the  raw material to set the offsets and measuring some feature  size etc only...no other serious probing. Machine is installed with Inspection plus & probe is RMP 60.

3) we started testing CAM (mastercam) based  probing just a week ago..with  CIMCO .

4)All the 3axis measuring  we did on the B0 side without any issue and it worked  good. We Checked ...hole dia & depth  , rectangle pocket size , single surface side angle check , Hole dia check and  re-cut by auto adjusting tool wear etc on B0 face..

5) PATH OBSTRUCTION  error pop-up when  rotated the B axis table to 90 ( B+90/-90/45/30 etc )  to check the  features on the B90 face .  Probe switch on at 9832 then goes to the line 9810 and throws the alarm but still the probe is around 60mm above the part surface. 

6) Job mounted on  Tombstone face - B0 

Please look at the code below and if anyone can point out my mistake...

is the probe eye getting blocked by the machine?

 

also there may be a parameter to adjust when using g68.2 while probing

[tryon]

Try adding a longer dwell after your probe turns on in program 9832.  Add a second to whatever is already there.

I work for Doosan. probing works well on that machine. I think you may be trying to enter machine interference zone. How close to the machine table are you in Y Axis? How close is the spindle face in the Z Axis are you to the machine table. That machine does have a couple of interference zones you need to be mindful of.

He's using an RMP probe. R is for  radio. O is optical.  No optics involved for him.

I may be a little late to this party but I use Doosan 1250's and those codes wont work on my machine. I would change this:

N50 G65 P9810 X20. Y17.5423 Z70. F600.

to this:

N50  M165 P9810 X20. Y17.5423 Z70. F600.

You use M165 on every line but that one. Our Doosan's require M165 instead of G65 on probing. I also don't need to use P9833/P9832 in my probing, its automatic.

I would agree with gms1 - The Doosans are generally setup with M165 vs G65. Here is a picture from a Doosan Manual that uses the M165 for the 9810 (Protected Positioning cycles)
