Module 23: Cutting Screw Threads on a Lathe (Core)
Outcome
Investigate the
cutting of screw
threads on a lathe.
Indicators
| (a) | Perform safe practices when cutting threads on a lathe. |
| (b) | Identify thread types using gauges (e.g., ACME, 60-degree V, multi-start and tapered pipe). |
| (c) | Demonstrate a lathe set-up for cutting threads. |
| (d) | Select the appropriate form cutting tool to suit thread application. |
| (e) | Calculate thread depth using the appropriate formula. |
| (f) | Assess class of thread fit (i.e., external threads 1A, 2A and 3A and internal threads 1B, 2B and 3B) using gauges and fasteners. |
| (g) | Explore thread measuring techniques (e.g., screw pitch gauge, measuring threads over wires and thread micrometers). |
| (h) | Perform thread cutting process (e.g., imperial, metric, external, internal) on a lathe. |
