- Page 51.1 Small-Hole Peck Drilling Cycle An arbor with the overload torque detection function is used to retract the tool when the overload torque detection signal (skip signal) is detected during drilling. Drilling is resumed after the spindle speed and cutting feedrate are changed. These steps are repea

- Page 7Note When receiving overload torque detect signal while the tool is advancing, the tool will be retracted (clearance ∆ and to the point R), then advanced to the same target point as previous advancing. - Changing the drilling conditions In a single G83 cycle, drilling conditions are changed for each
- Page 8When the cutting feedrate reaches the minimum rate, the spindle speed is not changed. The spindle speed can be increased up to a value corresponding to the maximum value of S analog data. - Advance and retraction Advancing and retraction of the tool are not executed in the same manner as rapid-trave
- Page 9- Custom macro interface The number of retractions made during cutting and the number of retractions made in response to the overload signal received during cutting can be output to custom macro common variables (#100 to #149) specified in parameters No.5170 and No.5171. Parameters No.5170 and No.51

- Page 112.1 Small-Hole Peck Drilling Cycle General In peck drilling, the tool enters and retracts from hole based on an overload torque detection signal (skip signal) until the designed hole depth is reached. The spindle speed and cutting feedrate are changed on each entry of the hole. The cycle is realized

Cutting feed rate = F × α (First time) α = 1.0 (Second and subsequent times) α = α × β ÷ 100 (where β is the rate of change for each drilling operation Skip du
