Repetition
Specify the number of repeats in K in order to repeat the drilling for equally spaced
holes. K only becomes effective in the block where it is specified. Specifying the
first hole in absolute mode (G90) results in drilling at the same position. Therefore,
specify K in incremental mode (G91).
Comments
A cycle call remains selected until it is cancelled through the G codes G80, G00,
G01, G02, or G03, or through another cycle call.
Within the machining cycles the data specified at address Z, R, P, and Q function
as self--retaining even after RESET operation. These data can only be changed by
reprogramming or are cancelled using the G codes G80, G00, G01, G02, or G03.
Symbols in figures
Subsequent sections explain the individual canned cycles. Figures in these
explanations use the following symbols:
