8 Cycles 8.2 Simple Fixed Cycles TNC 360 Example: Tapping with a floating tap holder Cutting an M6 thread at 100 rpm Coordinates of the hole: X = 50 mm Y = 20 mm Pitch p = 1 mm F = S x p ➞ F = 100 . 1 = 100 mm/min Setup clearance: 3 mm Thread depth: 20 mm Dwell time: 0.4 s Feed rate: 100 mm/min TAPPING cycle in a part program %S87I G71 * ..............................................................

8 Cycles 8.2 Simple Fixed Cycles RIGID TAPPING G85 8-8 Process The thread is cut without a floating tap holder in one or several passes. Advantages over tapping with a floating tap holder: • Higher machining speeds • Repeated tapping of the same thread; repetitions are made possible by spindle orientation to the 0° position during cycle call (depending on machine parameters) • Increased traverse range of the spindle axis Machine and control must be specially prepared by the machine manufacturer to enable rigid tapping. Input data • SETUP CLEARANCE A : Distance between tool tip (starting position) and workpiece surface. • TAPPING DEPTH B : Distance between workpiece surface (beginning of thread) and end of thread • THREAD PITCH C : The sign differentiates between right-hand and left-hand threads: + = Right-hand thread – = Left-hand thread Z Fig. 8.3: Input data for the RIGID TAPPING cycle The control calculates the feed rate from the spindle speed. If the spindle speed override knob is turned during tapping, the control automatically adjusts the feed rate accordingly. The feed rate override is disabled. C A B X TNC 360
