 Working Principle of cnc turning. • In cnc lathe machine tool in movement against rotating work-piece. CNC Turning Working Principle • Tool movement in linear motion linear movement towards chuck • Work-piece is rotating cylinderical • Single point cutting tool is using for cutting. CUTTING TOOL   Types of CNC machines   • T.C = Turning Centre  • V.M.C = Vertical Machining centre   • H.M.C . = Horizontal Machining Centre  • V.T.L. = Vertical Machining Lathe  • T.M = Turn Mill        This I have told you about some types of machine which are very much used in production line nowadays. Each machine has its own distinct characteristics and a different way of controlling them. Transfer fixtures to the machine. Move the equipment in the machine. Move both the fixture and equipment in the machine. All machines have their own special features, these...

The three basic primary factors in any turning operation are spindle speed rpm), feed and depth of cut. These three are called adjustable cutting factors. Other factors are material types and types of tools. These two types are very important during the cutting operation. But the above three factors can be changed/adjusted by the operator at any time. Right Cutting Parameters Produces A Precise Output,Which Helps In Reducing Cycle Times, good surface finishing, And Machine Costs. The Speed And Motion Of The Cutting Tool Are Specified Through SeveralP That Can Be Modified For Different Operations Based Upon The Workpiece Material And Tool Size. What is the Feed, Cutting Speed, Spindle Speed and Depth of Cut? 1) . Spindle Speed In turning machine, the angular velocity of the spindle is called the "spindle speed". The unit of spindle speed is revolution per minute (rpm). 2). Cutting speed. Cutting speed is defined as the speed at which the cutting tool moves wi...

Turning is a form of machining, a material removal process, which is used to create rotational parts by cutting away unwanted material. The turning process requires a turning machine or lathe,  workpiece ,  fixture , and cutting tool. The workpiece is a piece of pre-shaped material that is secured to the fixture or chuck, which itself is attached to the turning machine, and allowed to rotate at high speeds. The tool is typically a single-point cutting tool that is also secured in the machine, although some operations make use of multi-point tools. The cutting tool feeds into the rotating workpiece and cuts away material in the form of small chips to create the desired shape. Turning is used to produce rotational, typically axi-symmetric, parts that have many features, such as holes, grooves, threads, tapers, various diameter steps, and even contoured surfaces . Turning is also commonly used as a secondary process to add or refine features on parts that were manufactured usi...

CNC stands for Computer Numerical Control. A CNC machine is a sophisticated metal (material) removing computerized machine on which we can make any complex shapes, which was not possible before, with high accuracy, repeatability, better quality, less rejection and mass production. Before NC and CNC machine, engineers cannot machining same product again and again with all the above qualities. CNC machine can perform works as lathe machine.
