Linear pattern on front face G743
Cycle G743 is used to machine linear drilling or milling patterns in
which the individual features are arranged at a regular spacing on
the face.
If the Final point ZE has not been defined, the drilling/milling cycle
of the next NC block is used as a reference
Using this principle, you can combine pattern definitions with
Drilling cycles (G71, G74, G36)
The milling cycle for a linear slot (G791)
The contour milling cycle with free contour (G793)
Parameters:
XK: Start point (Cartesian)
YK: Start point (Cartesian)
ZS: Start point of drilling/milling operation
ZE: Final point of drilling/milling operation
X: Start point (polar)
C: Start angle (polar angle)
A: Pattern ang. (reference: XK axis)
I: Final point of pattern (Cartesian)
Ii: Final point – pattern distance (Cartesian)
J: Final point of pattern (Cartesian)
Ji: Final point – pattern distance (Cartesian)
R: Distance to first/last hole
Ri: Length – Incremental distance
Q: Number of holes
Parameter combinations for defining the starting point and the
pattern positions:
Starting point of pattern:
XK, YK
X, C
Pattern positions:
I, J and Q
Ii, Ji and Q
R, A and Q
Ri, Ai and Q
