Machine configuration for the circular interpolation example
The following figure illustrates the relative positional relationship between
the workpiece and the tool head and their positions, as seen from the +Z
direction. The X and Y coordinate values shown in the figure are those on
the table-fixed programming coordinate system (which rotates as the C-axis
turns).
