Fundamental Geometrical Principles
1.1 Description of workpiece points
Example of turning positions
Points P1 and P2 are defined by the following coordinates:
P1 corresponds to X-20 Y-20 Z23
P2 corresponds to X13 Y-13 Z27
Example:Positions for milling
To state the infeed depth, we need to specify a numerical value for the third coordinate
(Z in this case).
Points P1 to P3 are defined by the following coordinates:
P1 corresponds to X10 Y45 Z-5
P2 corresponds to X30 Y60 Z-20
P3 corresponds to X45 Y20 Z-15
