Simple helical interpolation
With simplified helical programming, no pitch is defined, only a target point. Depending on the target point the result is a helical motion with maximum one complete rotation.
Syntax example for G17 plane: |
G02 | G03 X.. Y.. Z.. I.. J.. | R.. |
G02 | G03 | Circular interpolation CW / CCW |
X.. Y.. | Target point in XY plane in [mm, inch] |
Z.. | Target point on helical axis perpendicular to XY plane in [mm, inch] |
I.. J.. | Position of circle centre point of interpolation in XY plane (I in X, J in Y) in [mm, inch], according to G161/G162 |
R.. | Radius of interpolated circle (alternative to I,J) in [mm, inch] |
Syntax according to selected interpolation plane: |
Plane | Interpolation | Target point | Target point | Centre point/radius |
G17 | G02/G03 | X..Y.. | Z.. | I..J../R |
G18 | G02/G03 | Z..X.. | Y.. | K..I../R |
G19 | G02/G03 | Y..Z.. | X.. | J..K../R |
Programing Example
Helical interpolation in the XY plane counter-clockwise
The following helix is travelled:
Starting point a: X-10 Y0 Z0
Target point b: Z20
Helix centre point I, J: Zero point
N10 G17 G90 X-10 Y0 Z0 F500 G161
N20 G03 I0 J0 Z20
