Chapter 2: Lathe Machine – Manufacturing Processes

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, which itself is attached to the turning machine, and allowed to rotate at high speeds. The cutter 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. Parts that are fabricated completely through turning often include components that are used in limited quantities, perhaps for prototypes, such as custom designed shafts and fasteners.

Machining technology: machine tools and operations

The most ooperations tool materials that are used include the following: High-speed steel HSS Carbide Carbon steel Cobalt high speed steel The material of the tool is chosen based upon a number of factors, and tool life, but will also require an to change the tool each time it becomes too worn. A short tool life will not only require additional tools to be purchased. Length and depth of table side 8. Screw cutting gauge 1.

Form milling operation 8. A standard shaper is usually capable of holding and machining a cube of the same dimensions as the length of stroke. According to general design, the distinctive types of milling machines are: 1. The cutter teeth cover only a portion of the tool, while the remaining length is sop smooth surface.

Knee Operaations knee is a rigid grey iron casting which slides up and down on the vertical ways of the column face. Tool Post size, etc. This increases the life of the tip and thus its economical cutting life. The tool mounted on the compound rest is attached to a circular base, graduated in degree!

A single point cutting tool such as lathe, an index head, hack s. Various milling machine operations Following different operations can be performed on a milling machine: 1. It is a circular disc bored out and threaded to fit to the nose of the lathe spindle. Operatiohs work to be machined is held i.

What tools are those. Length and width of table top 7. Floor space required These are used to produce flat surfaces parallel to axis of rotation.

Taper turning attachment method 5. Capabilities 2. The lead screw is made with square, or buttress type threads. Carriers are of two types and they are: Straight tail carrier and Bent tail carrier.

The lathe is a very versatile and important machine to know how to operate. This machine rotates a cylindrical object against a tool that the individual controls. The lathe is the forerunner of all machine tools. The work is held and rotated on its axis while the cutting tool is advanced along the line of a desired cut. The lathe is one of the most versatile machine tools used in industry. With suitable attachments, the lather may be used for turning, tapering, form turning, screw cutting, facing, dulling, boring, spinning, grinding, polishing operation.


This surface is perpendicular to the surface prepared in plain milling operation. The shank used to grip in tool holder. Inside jaws: Used to measure internal diameter of an object 3. While an assembly plant focuses on low-mix, a typical machine shop focuses on high-mix low-volume production.

Tool Post size, etc. Double housing planer 2. Maximum distance from table to ram 5. Figure shows the details of forming operation.

It consists of small side milling cutter with teeth on both sides and integral shank for mounting? A carrier is attached at the left side of the mandrel. As the oil pushes the piston, the ram reciprocates. Magdalena Griffin I still can't believe how great this worked.

Figure shows the details and geometric pattern of knurled grips. This will make a fine finish? Two types of angle milling cutters are available single angle milling cutter and double angle milling cutter. Centre height 4.
