4.4 Linear interpolation (G1)
Function
With G1, the tool travels along straight lines that are parallel to the axis, inclined or in any
orientation in space. Linear interpolation permits machining of 3D surfaces, grooves, etc.
Milling:
Programming
G1 X… Y… Z … F…
Or
G1 AP=… RP=… F…
Parameters
G1 Linear interpolation with feedrate (linear interpolation)
X Y Z End point in Cartesian coordinates
AP= End point in polar coordinates, in this case the polar
angle
RP= End point in polar coordinates, in this case the polar
radius
F Feedrate in mm/min. The tool travels at feedrate F along a
straight line from the current starting point to the
programmed destination point. You can enter the
destination point in Cartesian or polar coordinates. The
workpiece is machined along this path.
Example: G1 G94 X100 Y20 Z30 A40 F100
The end point on X, Y, Z is approached at a feedrate of
100 mm/min; the rotary axis A is traversed as a
synchronized axis, ensuring that all four movements are
completed at the same time.
