Check Plane

Upper and Lower Check Planes (UCP and LCP) are used to limit the area of surface machining by specifying upper and/or lower Z levels which the tool cannot penetrate. The UCP and LCP may be used together, or independently. You can choose to machine at or rapid above the Z planes as described in the Skip and Glue parameters below.

Off

Off is the default setting for both Upper and Lower Check Planes. The machining area is not restricted in the Z Axis.

Skip

When Skip is selected, any portion of the surface that lies above the UCP, or below the LCP is not machined (skipped). The tool rapids up and over upon contacting the Check Plane, and feeds down again to the next unrestricted surface area.

Glue

If Glue is chosen, the portions of the surface tool path that lie above the UCP are projected down to the UCP, and portions that lie below the LCP are projected up to the LCP.

Note

The Z Level value for both UCP and LCP is a signed distance from the current MCS.
