CMM stuttering during linear open scans

Timbort
Hello,

Wondering if someone can help me. I amusing a star probe to scan a cylinder with a linear open. The probe seems to intermittently "stutter" during the scan and reports an error for workpiece lost contact. Wondering if anyone has had this issue and has any idea what might cause it.

The other thing is it seems to happen more in the morning after being unused all night but by the afternoon the problem largely clears up. Wondering if it is possibly something mechanical.

Thanks

  • Check out your Exec Controls settings. If it is set to RELEARN, the machine will dynamically adjust the scan path as it goes. This is great for reverse engineering something that you don't have a model for, but you need to slow your scanspeed down to get a smooth motion. The machine will have a much easier time of it if you set it for DEFINED.

    Another thing to consider is to use a Circle/Cylinder Scan or an Auto Circle/Cylinder set to Adaptive circle scan. Those essentially have a defined path built in.

    Otherwise, you can reduce the speed and acceleration settings. It is also possible that there is just something wrong with your machine. It is strange that the problem is inconsistent based on time of day.
