3-Dimensional Circular Interpolation
General
Specifying an intermediate and end point on an arc enables circular interpolation in a 3-
dimensional space.
Format
Explanation
- G code group
G02.4 and G03.4 are modal G codes of group 01. They therefore remain effective until
another G code in group 01 is specified.
- Start point, mid-point, and end point
An arc in a 3-dimensional space is uniquely defined with its start point (current position)
and a specified intermediate point and end point, as shown below. Two command blocks
are used to define this arc. The first command block specifies the tool path between the
start point and intermediate point. The second command block specifies the tool path
between the intermediate point and end point.

G03.4 can be used instead of G02.4 . The movement is the same
regardless of whether G02.4 or G03.4 is specified.
