Q.  
In an NC machining operation, the tool has to be moved from point (5, 4) to point (7, 2) along a circular path with centre at (5, 2). Before starting the operation, the tool is at (5, 4). The G and N codes for this motion are


Answer & Explanation

We want circular motion as mention in question,
G02 - for Circular clockwise circular interpolation.

Thus correct option is: B.
