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
A)N010 GO3 X7.0 Y2.0 I5.0 J2.0
B)N010 GO2 X7.0 Y2.0 I5.0 J2.0
C)N010 GO1 X7.0 Y2.0 I5.0 J2.0
D)N010 GOO X7.0 Y2.0 I5.0 J2.0

The correct G-code for moving in a circular path is G02 for clockwise motion or G03 for counterclockwise motion. Given the center of the circle at (5, 2) and the movement from (5, 4) to (7, 2), the direction is clockwise when viewed from the positive side of the Z-axis. Therefore, G02 is the correct code. The I and J parameters typically denote the distance from the starting point to the center in the X and Y directions, respectively, but in this context, they are not needed or are incorrectly applied, as G02 and G03 commands use I and J for radius or center offset values, not absolute positions. The correct command should specify the end point and possibly the radius or the direction of the arc, but the given options do not accurately represent how I and J are used. Despite this, based on the options provided and the need for a clockwise arc, option B is the closest correct choice.
