A hybrid 5-axis CNC milling machine
Precision Engineering, 2009Abstract 5-Axis CNC milling machines are important in a number of industries ranging from aerospace to consumer-die-mold machining because they can deliver high machining accuracy with a spindle tilting capacity. Most of these machines have serial mechanisms so that modest static and dynamic stiffness become very critical design issues when high ...

An Adaptive CNC System of a Milling Machine Tool
IFAC Proceedings Volumes, 1977Abstract An adaptive CNC(computer numerical control) system of a milling machine tool using a precise tool wear rate model is presented. In the system, the bending moments on the spindle are sensed and used for computing the fundamental parameters of cutting conditions such as work material hardness, cutter sharpness, and others.
