Learning Objectives

Indicator: 3.3.2.LI.2 - Recognise and gain understanding of turning, drilling and milling operations using the center-lathe machine.

By the end of the lesson, learners can:

State the working principles behind turning, drilling, and milling operations on a center-lathe machine.
Identify the machine parts and controls involved in performing each of the three operations.
Distinguish between the three operations by their tool movement, workpiece rotation, and the shape of the surface produced.
Explain, with examples, the types of workpieces or features each operation is best suited to produce.
Demonstrate safe and correct setup procedures for a simple turning operation on the center-lathe machine.
