Learning Objectives

Indicator: 2.2.2.LI.4 - Perform drawing, die and presses operation in sheet metal fabrication

By the end of the lesson, learners can:

Define drawing, die, and press operations and distinguish between drawing and the cutting and bending operations covered in Week 11 and Week 12.
Identify the main parts of a press tool (die, punch, stripper, blank holder) and state the function of each part.
Perform a simple drawing operation on sheet metal using available tools to produce a shallow cup or tray, following correct safety procedures.
Set up a die and press (or a simple press tool substitute) to cut and form sheet metal to a desired shape, demonstrating correct tool selection.
Evaluate a completed drawn component for common defects such as wrinkling, tearing, and springback, and suggest corrective measures.
