Rigid Tapping - Cycle84 - Siemens SINUMERIK User Manual

The limit distance is calculated within the cycle as follows:
● Up to a drilling depth of 30 mm, the value is set to 0.6 mm.
● For larger drilling depths, the limit distance is the result of
(RFP + SDIS - current depth) / 50. If this calculated value >7, a limit of 7 mm, maximum, is applied.
Programming example: Deep-hole drilling
This program executes the cycle CYCLE83 at the position X0. The first drill hole is drilled with a dwell time zero and
machining type chip breaking. The final drilling depth and the first drilling depth are entered as absolute values. The drilling
axis is the Z axis.

Description
Retraction plane (absolute)
Reference plane (absolute)
Safety clearance (enter without sign)
Final drilling depth (absolute)
Final drilling depth relative to the reference plane (enter without sign)
Dwell time at thread depth (chip breakage)
Direction of rotation after end of cycle
Values: 3, 4 or 5 (for M3, M4 or M5)
Thread lead as a thread size (signed):
Range of values 3 (for M3) to 48 (for M48); the sign determines the direction of rotation in
the thread
Thread lead as a value (signed)
Range of values: 0.001 ... 2000.000 mm); the sign determines the direction of rotation in the
thread
Spindle position for oriented spindle stop in the cycle (in degrees)
Speed for tapping
Speed for retraction
Tool axis (values : 1 = 1st axis of the current plane; 2 = 2nd axis of the current plane; 3 =
1)
3rd axis of the current plane)
Internal parameter; only the default value 0 is possible
Internal parameter; only the default value 0 is possible
Machining type (values: 0 = Tapping in one pass; 1 = Deep-hole tapping with chip breakage;
2 = Deep-hole tapping with chip removal)
