3.8.7 Frame calculation from three measuring points in space (MEAFRAME)
The MEAFRAME function is used to support measuring cycles. It calculates the frame from
three ideal points and the corresponding measured points.
When a workpiece is positioned for machining, its position relative to the Cartesian machine
coordinate system is generally both offset and rotated in relation to its ideal position. For exact
machining or measuring either a costly physical adjustment of the part is required or the
motions defined in the part program must be changed.
A frame can be defined by sampling three points in space whose ideal positions are known. A
touch-trigger probe or optical sensor is used for sampling that touches special holes precisely
fixed on the supporting plate or probe balls.
Syntax
MEAFRAME(<ideal points>,<measuring points>,<quality>)
Meaning
MEAFRAME: Function call
<ideal points>: 2-dim. REAL array containing the three coordinates of the ideal points
<measuring points>: 2-dim. REAL array containing the three coordinates of the measured points
