Question

In a Numerical control machining operation, the tool has to be moved from point
(5, 4) to point (7, 2) along a circular path with center at (5, 2). Before starting the operation, the tool is at (5, 4) .The correct G and M code for this motion is

• A. $\text{N 010 G 01 X 7.0 Y 2.0}$ L${}_F$
• B. $\text{N 010 G 00 X 7.0 Y 2.0}$ L${}_F$
• C. $\text{N 010 G 02 X 7.0 Y 2.0}$ L${}_F$
• D. $\text{N 010 G 03 X 7.0 Y 2.0}$ L${}_F$

Answer 1

The correct option is C $\text{N 010 G 02 X 7.0 Y 2.0}$ L${}_F$

Based on the above, to produce arc from (5, 4) to (7, 2) with center (5, 2) the tool has to move in the clockwise direction. Hence G02 is used
