Simple helical interpolation

At the simplified helical programming no pitch, but only a target point is defined. Dependent on the target point the result is a helical movement with maximally one complete rotation.

Syntax example for plane G17:

G02 | G03X<expr>Y<expr>Z<expr>I<expr>J<expr> | R<expr>

G02 | G03 Circular interpolation CW / CCW

X<expr> Y<expr> Target point in plane XY

Z<expr> Target point on the helical axis perpendicular to plane XY

I<expr> J <expr> Position of the circle center point of the interpolation in plane XY
(I in X, J in Y), corresponding to G161/G162.

R<expr> Radius of the circle to be interpolated (alternative to I,J)

Syntax corresponding to the selected interpolation plane:

Example:

Helical interpolation counterclockwise in plane XY with following "helix":

Starting point a: X-10 Y0 Z0

Target point b: Z20

Helix center I, J: zero point
