Grooving cycle
Type of machining for the roughing pass.
To select the type of grooving, place the cursor over the desired icon and press the two-
color key.
Selection of the starting point of the grooving operation in the center of the groove or at the starting
point of the groove:
The roughing process of the grooving starts at the center and goes on in the direction
of the starting point. Once the starting point has been reached, it returns to the center
and goes on in the direction of the final point until the end of the roughing operation.
The groove roughing process starts a the starting point of the groove.
This option is available in all 4 grooving levels. If zig-zag grooving is defined at levels 3
and 4, the walls of the groove are not vertical enough, they will not be machined in zig-zag.
Selection of the penetration step (pass) P and dwell t (in seconds) for chip removal in the first
grooving pass:
Selection of the penetration step (pass) to keep the tool from overheating and dwell for
chip removal after each pass.
This penetration in steps takes place during the first penetration and it is valid regardless
of the selected starting point (center or corner).
Selection of the zig-zag grooving for chip removal in the first grooving pass:
The chip relief selecting icon offers the zig-zag grooving option.
In the first pass, it machines in zig-zag with penetration according to parameter P.
It runs the rest of the passes machining down to the bottom. In order to take care of the
tool, first machine the center area towards the origin with one side of the cutter (left figure)
and then from the center to the opposite side with the other side of the cutter (right figure).
In any of the grooving options, even if a dwell has not been programmed in the last
roughing passes, a dwell will be applied in order to machine the whole surface of the part
with a uniform radius. The length of this delay will be the time it takes the spindle to rotate
a full revolution.
