Question

A CNC instruction G91G01X30Y40F100 commands the movement of tool along the path at a feed rate of 100 mm/min (G91-incrememtal format and G01-linear interpolation). The feed rate of the tool (in mm/min) along the X-axis will be ______.

Answer 1

Concept:

In the combined movement, the tool is moving for 50 mm with a speed of 100 mm/min whereas in the same time tool is travelling x-axis by only 30 mm.

Hence,

For 50 mm ⇒ 100 mm/min

For \(30mm \Rightarrow \frac{{100}}{{50}} \times 30 = 60\;mm/min\)
