9.5 Linear interpolation (G1)
Function
With G1 the tool travels on paraxial, inclined or straight lines arbitrarily positioned in space.
Linear interpolation permits machining of 3D surfaces, grooves, etc.

Linear interpolation with feedrate (linear interpolation)
End point in Cartesian coordinates
End point in polar coordinates, in this case polar angle
End point in polar coordinates, in this case polar radius
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.
