Workholding

Ever since CNC machining became the dominant method to cut and grind metal, a perception has existed that machining can be manipulated and easily simplified. With computers crunching the numbers, how hard can machining be?

Workholding involves much more than slapping a part in a vise or chuck and pushing the cycle-start button, according to the Workholding column in the April 2012 issue of Cutting Tool Engineering magazine.

When it comes to workholding, one size definitely does not fit all. For example, workholding setups for round parts have similarities to setups used for all other prismatic (nonround) parts, but the latter has unique challenges.

Part manufacturers are examining every aspect of the production process, from cutting tool parameters to workholding methods, to find ways to reduce costs and improve quality. Conversations with metalworking professionals have revealed a heightened awareness of the role that nonmachining changeover time plays in manufacturing costs. Shops know that speeding changeovers can save them money every time they switch a setup or move a part.

Since the dawn of CNC milling, machinists have been trying to squeeze more parts onto the table and position them quicker. That’s because to a machinist, it’s all about reducing setup time and cranking out more parts per hour.
