ARC cutting speed ??

[duggie-APE]

I'm new to MasterCAM and currently using X4.

 

I am cutting HPDE plastic panels (2D) and when the program is run on the CNC machine the cutting speed between an arc corner and straight cut is night and day. The arc is slowing right down and then the straight cut is running at light speed in a contour/outline cut toolpath using a 1/4" straight upcut bit. I am also using Flashcut to run the CNC machine.

 

Is there a way to change the arc feedrate / cut speed in MasterCAM ??

 

 

Any help would be appreciated.

 

Thanks, Doug J.

Is it the machine or the gcode?

There is one thing that's easy to check in Mastercam

In your Operations Manager look on the Tool Settings page

In the left colum there is a check box labeled

"Adjust arc feed"

If its checked, uncheck it

Thanks for the reply .... but, I did as you recommended and the "Adjust arc feed" is turned off.

 

I'm going to see if there is a way to adjust the speed in the FLASHCUT program.

 

Any more assitance would be appreciated.

Can you post the code?

If you are using cutter comp on the machine and the machine parameters are set to adjust feed rate on arc then the machine is adjusting the feed rate to maintain a constant surface feed rate based on the linear distance of the arc...

I used the configure option in Flashcut.... can't remember exactly but I had restrictions put on the arc movements in Flashcut.  I use a plasma and laser cutter and now have no problems.  It has something to do with max. arc feedrate if my memory serves me right (it doesn't serve me right most of the time).  Good luck
