Oval Rotation on Openings

Cartridges Involved

This Configuration element involves the following Cartridges.

Note: Not all cartridges are available for all CMC models.

The Oval Rotation field controls how much the foot block will rotate before cutting.

Adjust the Oval Rotation if you are getting Bumps or Feathers on an oval opening.

If you have too much rotation on an oval opening, you will get a Feather, too little and you will get a Bump.

Select the desired Cartridge Type Tab and then the bevel type you want to edit from the Current Bevel Type dropdown control before making adjustments. Select Current Bevel Type-Front of Mat if it is being cut from the front of the mat.

In Oval Rotation, eight points equals one degree of rotation.

Users usually make adjustments 4 points at a time.

Increase the Oval Rotation to turn the foot block clockwise to correct for a Bump.
