ISO programming
G221
Application
Related topics
- Defining an individual row with PATTERN DEF
- Defining an individual pattern with PATTERN DEF
Cycle run
- The control automatically moves the tool from its current position to the starting point for the first machining operation
Sequence:
- Move to 2nd set-up clearance (spindle axis)
- Approach the starting point in the working plane
- Move to set-up clearance above the workpiece surface (spindle axis)
- From this position, the control executes the last defined fixed machining cycle
- Then, the tool approaches the starting point for the next machining operation in the negative direction of the reference axis. The tool stops at the set-up clearance (or the 2nd set-up clearance)
- This procedure (steps 1 to 3) will be repeated until all machining operations from the first line have been completed. The tool is located above the last point of the first line
- The tool subsequently moves to the last point on the second line where it carries out the machining operation
- From this position, the tool approaches the starting point for the next machining operation in the negative direction of the reference axis.
- This procedure (step 6) will be repeated until all machining operations of the second line have been completed
- The tool then moves to the starting point of the next row
- All subsequent lines are machined in a reciprocating movement.
If you run this cycle in Program Run / Single Block mode, the control stops between the individual points of a point pattern.
Notes
Cycle 221 CARTESIAN PATTERN can be hidden with the optional machine parameter hidePattern (no. 128905).
- Cycle 221 is DEF-active. In addition, Cycle 221 automatically calls the last defined machining cycle.
Notes on programming
- If you combine Cycle 221 with one of the machining cycles 200 to 209 or 251 to 267, then the set-up clearance, the workpiece surface, the 2nd set-up clearance, and the rotary position that you defined in Cycle 221 will be effective for the selected machining cycle.
- Slot position 0 is not allowed if you use Cycle 254 in combination with Cycle 221.
