Fundamentals
The control provides cycles for frequently used figures. You can program these figures as pockets, islands, or boundaries.
These figure cycles offer the following benefits:
- You can conveniently program the figures and machining data without the need to program an individual path contour.
- Frequently needed figures can be reused.
- If you want to program an island or an open pocket, the control provides you with more cycles for defining the figure boundary.
- The Boundary figure type enables you to face-mill your figure

Description of function
With a figure, you can redefine the OCM contour data and cancel the definition of a previously defined Cycle 271 OCM CONTOUR DATA or of a figure boundary.
The control provides the following cycles for figure definition:
- 1271 OCM RECTANGLE, see Cycle 1271 OCM RECTANGLE (#167 / #1-02-1)
- 1272 OCM CIRCLE, see Cycle 1272 OCM CIRCLE (#167 / #1-02-1)
- 1273 OCM SLOT / RIDGE, see Cycle 1273 OCM SLOT / RIDGE (#167 / #1-02-1)
- 1274 OCM CIRCULAR SLOT, see Cycle 1274 OCM CIRCULAR SLOT (#167 / #1-02-1)
- 1278 OCM POLYGON, see Cycle 1278 OCM POLYGON (#167 / #1-02-1)
The control provides the following cycles for figure boundary definition:
- 1281 OCM RECTANGLE BOUNDARY, see Cycle 1281 OCM RECTANGLE BOUNDARY (#167 / #1-02-1)
- 1282 OCM CIRCLE BOUNDARY, see Cycle 1282 OCM CIRCLE BOUNDARY (#167 / #1-02-1)
Tolerances
The control allows you to store tolerances in the following cycles and cycle parameters:
Cycle number | Parameter |
---|---|
1271 OCM RECTANGLE | Q218 FIRST SIDE LENGTH, Q219 2ND SIDE LENGTH |
1272 OCM CIRCLE | Q223 CIRCLE DIAMETER |
1273 OCM SLOT / RIDGE | Q219 SLOT WIDTH, Q218 SLOT LENGTH |
1274 OCM CIRCULAR SLOT | Q219 SLOT WIDTH |
1278 OCM POLYGON | Q571 REF-CIRCLE DIAMETER |
You can define the following tolerances:
Tolerances | Example | Manufacturing dimension |
---|---|---|
DIN EN ISO 286-2 | 10H7 | 10.0075 |
DIN ISO 2768-1 | 10m | 10.0000 |
Nominal dimension | 10+0.01-0.015 | 9.9975 |
You can enter nominal dimensions with the following tolerances:
Combination | Example | Manufacturing dimension |
---|---|---|
a+-b | 10+-0.5 | 10.0 |
a-+b | 10-+0.5 | 10.0 |
a-b+c | 10-0.1+0.5 | 10.2 |
a+b-c | 10+0.1-0.5 | 9.8 |
a+b+c | 10+0.1+0.5 | 10.3 |
a-b-c | 10-0.1-0.5 | 9.7 |
a+b | 10+0.5 | 10.25 |
a-b | 10-0.5 | 9.75 |
Proceed as follows:
- Start the cycle definition
- Define the cycle parameters
- Select NAME in the action bar
- Enter a nominal dimension including tolerance
- The control produces the workpiece to comply with the mean tolerance value.
- If you program a tolerance that does not comply with the DIN standard or if you indicate tolerances incorrectly when programming nominal dimensions (e.g., by entering blanks), the control aborts execution and displays an error message.
- Ensure correct upper and lower case when entering the DIN EN ISO and DIN ISO tolerances. Entering space characters is not allowed.
