6.14 3-dimensional Circular Interpolation; G02.4, G03.4
Function and purpose
To issue a circular command over a 3-dimensional space, an arbitrary point (intermediate point)
must be designated on the arc in addition to the start point (current position) and end point. By
using the 3-dimensional circular interpolation command, an arc shape determined by the three
points (start point, intermediate point, end point) designated on the 3-dimensional space can be
machined.
An option is required to validate this function. If the option is not provided and the 3-dimensional
circular interpolation command is issued, a program error (P39) will occur.
