Some general points to consider
9.4 Some general points to consider
• A canned cycle may be defined anywhere in the program, that is, in the main program as well
as in a subroutine.
• Calls to subroutines can be made from a block within the influence of a canned cycle without
implying the cancellation of the canned cycle.
• The execution of a canned cycle will not alter the history of previous "G" functions.
• Nor will the spindle turning direction be altered. A canned cycle can be entered with any turning
direction (M03 or M04), leaving in the same direction in which the cycle was entered.
Should a canned cycle be entered with the spindle stopped, it will start in a clockwise direction
(M03), and maintain the same turning direction until the cycle is completed.
• Should it be required to apply a scaling factor when working with canned cycles, it is advisable
that this scale factor be common to all the axes involved.
• The execution of a canned cycle cancels radius compensation (G41 and G42). It is equivalent
to G40.
• If tool length compensation (G43) is to be used, this function must be programmed in the same
block or in the one before the definition of the canned cycle.
The CNC applies the tool length compensation when the longitudinal (perpendicular) axis starts
moving. Therefore, it is recommended to position the tool outside the canned cycle area when
defining function G43 for the canned cycle.
• The execution of any canned cycle will alter the global parameter P299.
