What is the designation for a jog key that moves the spindle along the Y-axis in the positive direction?

• A. -Y
• B. +Y
• C. -Z
• D. +Z

Answer: (B)

The designation for a jog key that moves the spindle along the Y-axis in the positive direction is indeed +Y. In CNC terminology, the coordinate system is typically defined such that the positive direction along any axis indicates movement away from the origin point of the machine. In this context, the Y-axis runs vertically on a standard Cartesian coordinate system, and moving in the positive direction means the spindle is moving upward or towards the operator, depending on the machine's orientation. This nomenclature is consistent across various CNC systems, where the "+" symbol indicates positive movement in that specific axis. Therefore, the notation +Y clearly indicates that the movement is in the upward or positive direction along the Y-axis.
