Final answer:
The two manual methods for moving the axes of a machine are by using jog keys and handwheel or using MDI and jog keys, typically on CNC machines. option c is correct
Step-by-step explanation:
option c is correct The two methods for moving the axes of a machine manually are: a) the use of jog keys and handwheel, which allows the operator to incrementally move the machine's axis with precision, and c) the use of MDI (Manual Data Input) and jog keys, where the MDI allows the operator to input coordinates or commands directly into the machine's control unit to move the axes to a specified position. These methods are commonly used on CNC (Computer Numerical Control) machines for positioning or setup purposes.
The two methods for moving the axes of a machine manually are:
Use of jog keys and handwheel
Use of MDI and jog keys
The use of the jog keys allows you to move the axes incrementally, while the handwheel provides more precise control. On the other hand, the MDI (Manual Data Input) allows you to directly input commands to move the axes.
