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.

Lathe Machine: Definition, Introduction, Parts, Types, Operations, and Specifications, (With PDF)

A shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is analogous to that of a lathe , except that it is archetypally linear instead of helical. A wood shaper is a similar woodworking tool, typically with a powered rotating cutting head and manually fed workpiece, usually known simply as a shaper in North America and spindle moulder in the UK. A metalworking shaper is somewhat analogous to a metalworking planer , with the cutter riding a ram that moves relative to a stationary workpiece, rather than the workpiece moving beneath the cutter. The ram is typically actuated by a mechanical crank inside the column, though hydraulically actuated shapers are increasingly used. Adding axes of motion to a shaper can yield helical toolpaths, as also done in helical planing. A single point cutting tool is rigidly held in the tool holder, which is mounted on the ram.

When I went to school for machining, I worked on a bunch of different projects that taught me the basics of the trade. From keychains to hammers, I did all the typical stuff. One thing that I found out after the program, though, is that the chess pieces and keychains were quickly lost, but the tools I made are still in my box and used daily 12 years later. This is a nice and simple project that is great for absolute beginners. If the budget is tight or selection is limited, though, you can just as easily use steel or aluminum. For example, this one has flats on the handle.

Process Cycle

So let me give you the introduction of the lathe machine tool. The Lathe was invented by Jacques de Vaucanson around 1. The Lathe Machine is an ancient tool. At the very early stage this machine was developed around BC at that time there was not developed so many parts expect headstock and Tailstock. But during the industrial revolution Metalworking lathe evolved into heavier machines with thicker, more rigid parts. Between 19 and 20 century the electric motor is replaced line shafting as a power source.
