11.1.1 Drilling operation
This operation is optional and in order to be executed it is necessary to also program a roughing
operation.
It is mainly used when the tool programmed in the roughing operation does not machine along the
longitudinal axis, allowing, by means of this operation, the access of this tool to the surface to be
roughed off.
It will be programmed in a block which will need to bear a label number in order to indicate to the
canned cycle the block where the drilling operation is defined.
The drilling canned cycles that can be programmed are:
G69 Complex deep hole drilling
G81 Drilling canned cycle.
G82 Drilling cycle with dwell.
G83 Deep hole drilling canned cycle with constant peck (drilling step).
When defining the drilling operation, the corresponding definition parameters must be programmed
together with the required function.
In a block of this type, only cycle definition parameters must be programmed, without defining XY
positioning, as the canned cycle itself will calculate the coordinate of the point or points to be drilled
according to the programmed profile and the roughing angle.
After the definition parameters, auxiliary F S T D M functions can be programmed, if so wished. No
M function can be programmed if it has an associated subroutine.
It is possible to program the M06 function in this block (if it does not have an associated subroutine),
to make the tool change. Otherwise, the CNC will show the corresponding error. If the M06 has an
associated subroutine, the drilling tool "T" must be selected before calling the cycle.
