I am trying to make a program for my CNC class.

Basically it drills a hole and then counterbores, with an end mill.

I set the Z pass incriment to .030, since I am using a .125 end mill ad counterboring .840 deep.

When the machine gets to the first cut in the counterbore, there is an error, saying that that line has no feed rate. The block before it is an arc, and has a feed rate, but the next block, also an arc, has none.

I would assume the machine would keep the feed rate until told to change it, but apparantly this is not the case.

Is there a way to get FeatureCAM to put feedrate word on each block that cuts an arc?

Thanks.

You can edit your post to output a feedrate on each line.
Go to "Edit Post"...
"Formats"...
"Move"...
"Circular"

Your post probably has a statement that looks like "{ F<FEED>}<EOB>"
The { } around the F<FEED> makes the feedrate only output if it changes. If you remove the conditional {} then the feedrate will output on every line.

However I would like to see your actual program because there is probably an underlying problem thats causing this alarm.

Here is a zip file of the code, which was origionally ControlArm.M, the error occurs on line 55, right after the tool change to #3, and the rapid into position.

Hope it helps.
