9.1 G66. Pattern repeat cycle canned cycle
This cycle machines the programmed profile maintaining the indicated step between consecutive
machining passes. Triangular, round and square tools may be used in this cycle.
The basic structure of the block is as follows:
G66 X Z I C A L M H S E Q
X±5.5
It sets the X coordinate of the profile's starting point. It must be programmed in absolute coordinates
and in the active units, radius or diameter.
Z±5.5
It sets the Z coordinate of the profile's starting point. It must be programmed in absolute coordinates.
I5.5
It defines the excess stock to be removed from the original part. It is defined in radius and depending
on the value assigned to parameter "A", this value will be interpreted as excess stock in X or in Z.
If its value is not greater than the finishing stock (L or M), it will only run the finishing pass, if H is
other than zero.
C5.5
It defines the machining pass. All the machining passes will be run with this step, except the last
one that will remove the residual stock.
It is defined in radius and depending on the value assigned to parameter "A", this value will be
interpreted, Like "I", as excess stock in X or in Z. If programmed with a 0 value, the CNC will display
the corresponding error message.
