How 5-Axis Machining Works: 3, 4 and 5-Axis Compared
Adding rotary axes to a milling machine does not make it more accurate. It makes it possible to hold accuracy across features that would otherwise need three or four separate setups, and that is a different claim. This page explains how 5-axis machining works: what actually changes as you move from 3-axis to 4-axis to […]
Wire EDM: How It Works and What It Can Hold
Wire EDM cuts by eroding metal with controlled electrical sparks rather than by pushing a tool through it. Because there is no cutting force, hardness stops being a constraint and geometry that would snap an end mill becomes routine. It is also slow, leaves a modified surface layer, and cannot cut anything that does not […]
