2.1.3 Circular Interpolation (MCW, MCC)

! Outline

The circular interpolation (MCW, MCC) command simultaneously moves 2 axes on the

designated plane, from the current position to the end position, along a circular arc

determined by the central position (U-V) or the radius value (R), by the interpolation feed

speed.

! Detailed Explanation

An example of the designating method is shown as follows:

The rotational direction of the circular interpolation command is shown as follows:

MCW: Clockwise (CW)

MCC: Counterclockwise (CCW)

Important Points

• Before executing the circular interpolation command, designate the plane of the circular

interpolation by the coordinate plane designation (PLN) command. For the circular

interpolation command, the rotational direction (MCW or MCC) of the circular arc must

be designated. Designate the end position and circular arc center of the horizontal axis

and the vertical axis on the designated plane using axis1 and axis2.

• Designate the end position and circular arc center in the order corresponding with the

horizontal axis and vertical axis names which are designated by the PLN command.
