Chapter 10 : Manual Lathes
OVERVIEW
The goal of this chapter is to gain a safe, entry-level, working knowledge of manual lathes. It is important for students to have the knowledge of this chapter because it gives them a foundation for the upper machining skills that revolve around CNC turning and programming. Students will be applying the contents of this chapter to their hands-on lab work that will accompany the units. They will also apply the information once employed at machine shops.
OBJECTIVES
- Identify and address the safety concerns of operating a lathe.
- Identify and select tooling for use on a lathe
- Calculate the speeds and feeds for turning operations.
- Identify and select tool holding and work holding devices.
- Describe proper setup solutions.
- Describe various operations performed on a lathe.
