Machining And Program Run - HEIDENHAIN iTNC 530 Service Manual

30.4.14 Machining and Program Run

MP Function and input
MP7400 Look-ahead – Number of NC blocks for advance calculation of the path
Input:
1: 512 [blocks]
2: 1024 [blocks]
MP7410 Scaling cycle in two or three axes
Input:
1: Scaling cycle is effective only in the working plane
MP7411 Tool data in the touch probe block
Input:
0: Use the calibrated data of the touch probe
1: Use the current tool data from the last TOOL CALL
Bit 1 –
0: Only one set of touch probe calibration data
1: Use the tool table to manage more than one set of touch probe calibration data
MP7420 Cycles for milling pockets with combined contours
Format:
Input:
0: Counterclockwise for pockets, clockwise for islands
1: Clockwise for pockets, counterclockwise for islands
Bit 1 – Sequence for rough-out and channel milling (only for SL 1):
0: First channel milling, then pocket rough-out
1: First pocket rough-out, then channel milling
Bit 2 – Merging of listed contours:
0: Contours are merged only if the tool-center paths intersect
1: Contours are merged if the programmed contours intersect
Bit 3 – Rough-out and channel milling to pocket depth or for every infeed
0: Each process uninterrupted to pocket depth
1: Both processes for each pecking depth before proceeding to the next depth
Bit 4 – Position after completion of the cycle
0: Tool moves to the same position as before the cycle was called
1: Tool only moves in the tool axis to the "clearance height"
MP7430 Overlap factor for pocket milling
Input:
MP7431 Arc end-point tolerance
Input:
MP7432 Limit-switch tolerance for M140 / M150
Input:
0: Limit-switch tolerance not active
July 2010
