Point Marking with Datum Points and Edges
- Datum points and edges are points and edges of the workpiece that you measure from.
- In most cases, 2 datum edges will be used. How to measure using 2 datum edges is shown in the diagram below.
Match Drilling
- Set 2 components one on top of the other, mount securely, then drill through both pieces at the same time for exact matching accuracy.
- Match drilling works effectively with templates
- Match drilling works effectively for pieces before they are cut apart
