CHAPTER 3Transmission Systems

There are many ways in which power from a motor can be applied to machinery for various types of movement. Methods such as hydraulic, pneumatic, belt, chain, cable, rack and pinion, and screws are but a few that can be used. However, when dealing with CNC, we are particularly interested in obtaining resolution and accuracy, as well as bidirectional travel. In this chapter, we will discuss the two most common methods in which the rotary power from the motor is translated into linear motion. The function of the transmission system is to translate the rotational power of the motor into linear movement. To meet these criteria, almost all CNC equipment will use either rack and pinion or some type of screw and nut mechanism ...
