A workpiece holding device’s fixed point limits movement along one axis, ensuring consistent positioning for repetitive machining operations. For example, multiple identical cuts can be made on a series of parts without readjusting the workpiece placement.
This fixed reference point is crucial for precision and efficiency in milling. It allows for repeatable cuts, minimizing setup time and maximizing productivity. Historically, machinists relied on less sophisticated methods, involving manual measurements and adjustments. The introduction of adjustable hard stops significantly improved accuracy and repeatability, paving the way for automation and mass production. This advancement reduced errors and ensured consistent part dimensions.
