3. 1.2 Introduction Milling is a cutting operation with a geometrically specified cutting edge in which the tool makes the rotating main movement, and the feed as well as the infeed movement are generally made by the work part. Milling operations are classified according to the position of the milling axis towards the work part, i.e. between face milling and peripheral milling.•What is a CNC Machine? •CNC : Computer Numerical Control •Conventionally, an operator decides and adjusts various machines parameters like feed , depth of cut etc depending on type of job , and controls the slide movements by hand. In a CNC Machine functions and slide movements are controlled by motors using computer programs.

8. Feed drives Introduction • The driving system is an important component of a CNC machine as the accuracy and repeatability depend very much on the characteristics and performance of the driving system. • The driving system is classified as spindle drives and feed drives. • The spindle drives are used to provide angular motion to the work piece or a cutting tool. This document discusses the constructional features of CNC machines. It classifies CNC systems according to the type of machine into point-to-point, straight-cut, and continuous path systems. It also categorizes them based on programming method as absolute or incremental, and by control system type as open-loop or closed-loop. 3. CNC MACHINING The use of computers to control machine tools Tools include lathes, mills, drills and grinders. Machine tools function through numerical control A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) Controls all features like feed rate, coordination, location and speeds 3 CNC Machines - Download as a PDF or view online for free.
