Projection planes

A projection plane is the lateral extension of one axis along another axis in the
machine coordinate system.

For example, the XY plane is the lateral extension of the X axis along the Y axis.

Machine coordinates

Machine coordinates describe the distance of points within the measuring enve-
lope from machine zero. Until a reference frame is created the QC5000 displays
machine coordinates in the DRO window. Once a reference frame is estab-
lished the DRO display part coordinates.

Part coordinates

Part coordinates describe the distance of points from the datum, or zero point,
of the reference frame. Reference frames are created by probing a primary plane,
a secondary line, and a zero point.
