The export version of the TNC has the following limitations: Linear movement is possible in no more than 4 axes simultaneously. [. . . ] There is no chip breaking if 0 is entered. Retraction rate for chip breaking Q256 (incremental value): Value by which the TNC retracts the tool during chip breaking. Dwell time at depth Q211: Time in seconds that the tool remains at the hole bottom. Deepened starting point Q379 (incremental with respect to the workpiece surface): Starting position of drilling if a shorter tool has already pilot drilled to a certain depth. The TNC moves at the feed rate for pre-positioning from the set-up clearance to the deepened starting point. Feed rate for pre-positioning Q253: Traversing velocity of the tool during positioning from the set-up clearance to a deepened starting point in mm/min. Effective only if Q379 is entered not equal to 0. If you use Q379 to enter a deepened starting point, the TNC merely changes the starting point of the infeed movement. Retraction movements are not changed by the TNC, therefore they are calculated with respect to the coordinate of the workpiece surface. 11 CYCL DEF 205 UNIVERSAL PECKING Q200=2 Q201=-80 Q206=150 Q202=15 Q203=+100 Q204=50 Q212=0. 5 Q205=3 Q258=0. 5 Q259=1 Q257=5 Q256=0. 2 Q211=0. 25 Q379=7. 5 Q253=750 ;SET-UP CLEARANCE ;DEPTH ;FEED RATE FOR PLUNGING ;INFEED DEPTH ;SURFACE COORDINATE ;2ND SET-UP CLEARANCE ;DECREMENT ;MIN.

The tool mills in a helix from the current position to the first plunging depth at the programmed feed rate F. When the drilling depth is reached, the TNC once again traverses a full circle to remove the material remaining after the initial plunge. The TNC then positions the tool at the center of the hole again Finally the TNC returns to the set-up clearance at FMAX. If programmed, the tool moves to the 2nd set-up clearance at FMAX. Before programming, note the following: Program a positioning block for the starting point (hole center) in the working plane with radius compensation R0. The algebraic sign for the cycle parameter DEPTH determines the working direction. If you program DEPTH = 0, the cycle will not be executed. If you have entered the bore hole diameter to be the same as the tool diameter, the TNC will bore directly to the entered depth without any helical interpolation. 2 3 4 5 Enter in MP7441 bit 2 whether the TNC should output an error message (bit 2=1) or not (bit 2=0) if a positive depth is entered. Keep in mind that the TNC reverses the calculation for prepositioning when a positive depth is entered. This means that the tool moves at rapid traverse in the tool axis at safety clearance below the workpiece surface! 320 8 Programming: Cycles Set-up clearance Q200 (incremental value): Distance between tool lower edge and workpiece surface. Depth Q201 (incremental value): Distance between workpiece surface and bottom of hole.
