Dovetail fixturing: it’s not just for 5 axis machining.
You can incorporate dovetail machining into any milling operation with substantial benefit, not just five axis.
You ask yourself “How much do we need for holding so the part doesn’t fly out during a heavy roughing cut? Quarter inch in the the vise? 1/2 inch? more?”
Using a simple 1/8″ dovetail cut on you stock eliminates the need for using large deep step jaws for holding. A dovetail presents the optimum holding with the minimum of stock. Especially true in 5 axis machining, using a dovetail in 3 and 4 axis machinin keeps stock excess stock to a minimum. The result:
- smaller stock sizes need resulting in lower material costs
- Less machine time in remove excess stock
