What is the designation for a jog key that rotates machine components around the A-axis in a positive direction?

• A. -A
• B. +A
• C. -B
• D. +B

Answer: (B)

The designation for a jog key that rotates machine components around the A-axis in a positive direction is denoted by the symbol "+A." In CNC terminology, each axis of movement is assigned a letter, with "A" typically representing the axis that allows for rotation around a particular point in three-dimensional space. In this context, a positive rotation means that the component is moving in a direction that is considered upward or counterclockwise when viewed from a defined perspective. The "+" sign indicates the positive direction of rotation for that axis, which is a standard convention in CNC programming and operation. Therefore, using "+A" for positive rotation aligns with these established conventions, making it the correct answer in this scenario.
