Case B:
When the machining paths are concentric.
The roughing operation is carried out along paths concentric to the profile. The machining will
be done as fast as possible avoiding (when possible) going over the islands.
3. Finishing operation. Only if it has been programmed.
This operation can be done on a single pass or on several, as well as following the profiles in
the programmed direction or in the opposite.
The CNC will machine both the external profile and the islands, making tangential approaches
and exits to these with a constant surface speed.
Reference coordinates:
In the pocket canned cycle with islands, there are four coordinates along the longitudinal axis
(selected with G15), which, due to their importance, are discussed below:
1. Initial plane coordinate. This coordinate is given by the position which the tool occupies when
the cycle is called.
2. Coordinate of the reference plane. This represents an approach coordinate to the part, and must
be programmed in absolute coordinates.
3. Part surface coordinate. This is programmed in absolute coordinates and in the first profile
definition block.
4. Machining depth coordinate. It must be programmed in absolute values.
Conditions after finishing the cycle
Once the canned cycle has ended, the active feedrate will be the last one programmed, i.e. the one
corresponding to the roughing operation or the finishing operation. The CNC will assume functions
G00, G40 and G90.
