C-axis groove: G1670 (cylindrical surface)
On the peripheral surface of a workpiece, grooves are cut by rotating the
C-axis with the Z-axis position of the tool fixed. Multiple grooves of the
same figure can be cut.
POS./SIZE
Data item Meaning
B BASE POSITION X coordinate of the bottom of a groove or the top
surface of a workpiece subject to grooving (in the tool
axis direction)
L HEIGHT/DEPTH When the top surface of a workpiece is selected as the
BASE POSITION, specify the distance to the bottom of
the groove by using a negative value (radius value).
→ Depth
When the bottom of a groove is selected as the BASE
POSITION, specify the distance to the top surface of the
groove by using a positive value (radius value).
→ Height
Z Z AXIS POS. Z coordinate of the center line of a groove
Q GROOVE ANGLE Center angle formed by the start point (tool center) and
end point (tool center) of a groove (positive or negative
value)
A START ANGLE C coordinate of the start point (tool center) of the first
groove
REPEAT
Data item Meaning
C* PITCH ANGLE Center angle formed by the start points (tool centers) of
two adjacent grooves (positive or negative value)
M
*
GROOVE NUMBER Number of grooves to be cut (positive value)
