Assignment
Working in a team of four, use SolidWorks, SolidCAM, the Haas TL-1 and other tools to create a full chess set, including the board.

Deliverables
1. Complete chess set with board.


Guidelines

  • A member of the teaching staff must be present when you first cut your parts on the TL-1. A schedule with the TA's available times can be found on Piazza. Your ENTIRE team must be present for the training.
  • Your parts will be oriented such that the origin sits at the intersection of the machine's Z axis and the face of the chuck, with positive Z pointing towards the tailstock.
  • To allow for post machining (mill, secondary manual lathe ops), you may want to leave a short section at a standard diameter for insertion into a collet.
  • Alternatively, you can pre-machine chess piece blanks and a threaded mandrel to fixture onto the TL-1 to avoid having to flip your part later.
  • The parts can be sent out for anodizing after they are all completed. The anodizing supplier asks that you have a 1/4-20 threaded hole somewhere on each part.
  • See below for materials that will be provided. All others must be requested and ordered by the teaching staff from McMaster preferable.
  • Material budget: $250 /team.


Setup

  • The TL-1 will be set up with an 8" chuck with a maximum spindle speed of 1800 RPM.
  • We will pre-set right and left-handed carbide turning/facing tools, a part-off tool, and a drill and tap for threaded holes for anodizing. The tool table (in .TAB and .XLS format) can be found on Piazza.
  • The chuck on the TL-1 will be checked for collisions by creating a fixture in SolidCAM with the following dimensions:
Chuck Dimension Value
Jaw Width 1.75
Jaw Height 3.125
Step Width 0.375
Step Height 1.0
Thickness 1.0625
Number of Jaws 3

Materials

  • 1.125" and 1" aluminum rod stock will be in inventory. Please still list on the BOM so that we can make sure we have enough in stock.
