2. FUNCTION TO SIMPLIFY
(For the Power Mate i–D/D2)
The positioning plane is determined by plane selection code G17, G18,
The positioning axis is an axis other than the drilling axis.
Although canned cycles include tapping and boring cycles as well as
drilling cycles, in this chapter, only the term drilling will be used to refer
to operations implemented with canned cycles.
The drilling axis is a basic axis (X, Y, or Z) not used to define the
positioning plane, or any axis parallel to that basic axis.
The axis (basic axis or parallel axis) used as the drilling axis is determined
according to the axis address for the drilling axis specified in the same
block as G codes G73 to G89.
If no axis address is specified for the drilling axis, the basic axis is
assumed to be the drilling axis.
Table 2.1 (b) Positioning plane and drilling axis
G code Positioning axis Drilling axis
G17 Xp axis Zp
G18 Zp axis Yp
G19 Yp axis Xp
Xp : X axis or an axis parallel to the X axis
Yp : Y axis or an axis parallel to the Y axis
Zp : Z axis or an axis parallel to the Z axis
Assume that the U, V and W axes be parallel to the X, Y, and Z axes
respectively. This condition is specified by parameter No.1022.
G17 G81 ………Z _ _ : The Z axis is used for drilling.
G17 G81 ………W _ _ : The W axis is used for drilling.
G18 G81 ………Y _ _ : The Y axis is used for drilling.
G18 G81 ………V _ _ : The V axis is used for drilling.
G19 G81 ………X _ _ : The X axis is used for drilling.
G19 G81 ………U _ _ : The U axis is used for drilling.
G17 to G19 may be specified in a block in which any of G73 to G89 is
Switch the drilling axis after canceling a canned cycle.
A parameter FXY (No.5101 #0) can be set to the 1st axis
always used as the drilling axis. When FXY=0, the 1st axis
is always the drilling axis.
