Cylindrical interpolation by the developed
cylindrical surface command

[] : Rounded to the least input increment
Restrictions
Arc radius specification in the cylindrical interpolation mode
In the cylindrical interpolation mode, an arc radius cannot be specified with word address I, J,
or K.
Circular interpolation and tool nose radius compensation
If the cylindrical interpolation mode is started when tool nose radius compensation is already
applied, circular interpolation is not correctly performed in the cylindrical interpolation mode.。
Positioning
In the cylindrical interpolation mode, positioning operations (including those that produce
rapid traverse cycles such as G28, G80 through G89) cannot be specified. Before positioning can
be specified, the cylindrical interpolation mode must be cancelled. Cylindrical interpolation
(G07.1) cannot be performed in the positioning mode (G00).
Coordinate system setting
In the cylindrical interpolation mode, a workpiece coordinate system G50 cannot be specified.
Cylindrical interpolation mode setting
In the cylindrical interpolation mode, the cylindrical interpolation mode cannot be reset. The
cylindrical interpolation mode must be cancelled before the cylindrical interpolation mode can
be reset.
Canned cycle for drilling during cylindrical interpolation mode
Canned cycles for drilling, G81 to G89, cannot be specified during cylindrical interpolation
mode.
Mirror Image for Double Turret
Mirror image for double turret, G68 and G69, cannot be specified during cylindrical
interpolation mode.
