Defining A Single Pattern - HEIDENHAIN TNC 620 User Manual

Using Fixed Cycles | PATTERN DEF pattern definition

Defining a single pattern

If you have defined a Workpiece surface in Z not equal to
0, then this value is effective in addition to the workpiece
surface Q203 that you defined in the machining cycle.
The Rotary pos. ref. ax. and Rotary pos. minor ax.
parameters are added to a previously performed Rot.
position of entire pattern.
Starting point in X (absolute): Coordinate of the
starting point of the pattern in the X axis
Starting point in Y (absolute): Coordinate of the
starting point of the pattern in the Y axis
Spacing of machining positions X (incremental):
Distance in X direction between the machining
positions. You can enter a positive or negative
value
Spacing of machining positions Y (incremental):
Distance in Y direction between the machining
positions. You can enter a positive or negative
value
Number of columns: Total number of columns in
the pattern
Number of rows: Total number of rows in the
pattern
Rot. position of entire pattern (absolute): Angle
of rotation by which the entire pattern is rotated
around the entered starting point. Reference axis:
Reference axis of the active machining plane
(e.g. X for tool axis Z). You can enter a positive or
negative value
Rotary pos. ref. ax.: Angle of rotation around
which only the reference axis of the machining
plane is distorted with respect to the entered
starting point. You can enter a positive or negative
value.
Rotary pos. minor ax.: Angle of rotation around
which only the minor axis of the machining plane
is distorted with respect to the entered starting
point. You can enter a positive or negative value.
Coordinate of workpiece surface (absolute):
Enter Z coordinate at which machining is to begin
