TNC model iTNC 530 iTNC 530 E iTNC 530 iTNC 530 E iTNC 530 programming station NC software number 340 490-02 340 491-02 340 492-02 340 493-02 340 494-02 The suffix E indicates the export version of the TNC. The export version of the TNC has the following limitations: Linear movement is possible in no more than 4 axes simultaneously. [. . . ] When a cycle is being run, the spindle speed override knob is disabled. The feed-rate override knob is active only within a limited range, which is defined by the machine tool builder (refer to your machine manual). For tapping right-hand threads activate the spindle with M3, for left-hand threads use M4. 4 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! 322 8 Programming: Cycles Set-up clearance Q200 (incremental value): Distance between tool tip (at starting position) and workpiece surface. Total hole depth Q201 (thread length, incremental value): Distance between workpiece surface and end of thread. Dwell time at bottom Q211: Enter a value between 0 and 0. 5 seconds to avoid wedging of the tool during retraction. Workpiece surface coordinate Q203 (absolute value): Coordinate of the workpiece surface. 2nd set-up clearance Q204 (incremental value): Coordinate in the tool axis at which no collision between tool and workpiece (clamping devices) can occur. The feed rate is calculated as follows: F = S x p F Feed rate (mm/min) S: Spindle speed (rpm) p: Thread pitch (mm) Retracting after a program interruption If you interrupt program run during tapping with the machine stop button, the TNC will display a soft key with which you can retract the tool.

The TNC cuts the thread without a floating tap holder in one or more passes. 1 2 3 The TNC positions the tool in the tool axis at rapid traverse FMAX to the programmed set-up clearance above the workpiece surface. Once the tool has reached the total hole depth, the direction of spindle rotation is reversed and the tool is retracted to the set-up clearance at the end of the dwell time. The TNC stops the spindle turning at set-up clearance 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 total hole depth parameter determines the working direction. If the spindle speed override is used during tapping, the feed rate is automatically adjusted. Before the next operation, restart the spindle with M3 (or M4). 4 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! 324 8 Programming: Cycles Set-up clearance Q200 (incremental value): Distance between tool tip (at starting position) and workpiece surface. Total hole depth Q201 (incremental value): Distance between workpiece surface and end of thread. The algebraic sign differentiates between right-hand and left-hand threads: += right-hand thread ­= left-hand thread Workpiece surface coordinate Q203 (absolute value): Coordinate of the workpiece surface. [. . . ] Please note that the data drive of the iTNC appears in the file manager with the name TNC:\. In Windows Explorer, this drive (partition) appears with the letter D. RECYCLER and SYSTEM VOLUME IDENTIFIER) are created by Windows 2000 and may not be deleted. With machine parameter 7225 you can define letters of drives that should not be shown in the file management of the TNC. [. . . ]
