Q203 Workpiece surface coordinate? Coordinate on the workpiece surface referenced to the active datum. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q201 Depth? Distance between the workpiece surface and the contour floor. This value has an incremental effect. Input: –99999.9999...+0 | |
Q368 Finishing allowance for side? Finishing allowance in the working plane. This value has an incremental effect. Input: 0...99999.9999 | |
Q369 Finishing allowance for floor? Finishing allowance for the floor. This value has an incremental effect. Input: 0...99999.9999 | |
Q260 Clearance height? Coordinate in the tool axis in which no collision with the workpiece can occur (for intermediary positioning and retraction at the end of the cycle). This value has an absolute effect. Input: –99999.9999...+99999.9999 or PREDEF | |
Q578 Radius factor on inside corners? The inside radii of the contour are calculated based on the tool radius plus the product of the tool radius times Q578. Input: 0.05...0.99 | |
Q569 Is the first pocket a boundary? Define the boundary: 0: The first contour in CONTOUR DEF is interpreted as a pocket. 1: The first contour in CONTOUR DEF is interpreted as an open boundary. The following contour must be an island 2: The first contour in CONTOUR DEF is interpreted as a "bounding block." The following contour must be a pocket Input: 0, 1, 2 |
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
