8 Cycles 8.2 Simple Fixed Cycles TAPPING with floating tap holder G84 8-6 Process • The thread is cut in one pass. • When the tool reaches the total hole depth, the direction of spindle rotation is reversed. After the programmed dwell time the tool is retracted to the starting position. • At the starting position, the direction of rotation is reversed once again. Required tool A floating tap holder is required for tapping. The floating tap holder compensates the tolerances for feed rate and spindle speed during the tapping process. 1. 2. 3. 4. Fig. 8.2: TAPPING cycle Input data • SETUP CLEARANCE A : Distance between tool tip (starting position) and workpiece surface. Standard value: 4x thread pitch. • TOTAL HOLE DEPTH B (thread length): Distance between workpiece surface and end of thread. • DWELL TIME: Enter a dwell time between 0 and 0.5 seconds to prevent wedging of the tool when retracted. (Further information is available from the machine tool builder.) • FEED RATE F: Traversing speed of the tool during tapping. Calculations The feed rate is calculated as follows: F = S x p F: Feed rate (mm/min) S: Spindle speed (rpm) p: Thread pitch (mm) • When a cycle is being run, the spindle speed override control is disabled. The feed rate override control is only active within a limited range (preset by the machine tool builder). • For tapping right-hand threads activate the spindle with M3; for left-hand threads use M4.
