Machining is one of the most important material removal methods in the technology of manufacturing It is basically a collection of material working processes that involves other processes such as drilling shaping sawing planning reaming and grinding among others Machining is practically a part of the manufacture of all metals and other materials such as plastics and wood as well An important machine that is useful in machining is the lathe machine.
A lathe machine is generally used in metalworking metal spinning woodturning and glassworking The various operations that it can perform include the following sanding cutting knurling drilling and deforming of tools that are employed in creating objects which have symmetry about the axis of rotation Some of the most common products of the lathe machine are crankshafts camshafts table legs bowls and candlestick holders.
The first lathe machine that was ever developed was the two person lathe machine which was designed by the Egyptians in about 1300 BC Primarily there are two things that are achieved in this lathe machine set up The first is the turning of the wood working piece manually by a rope and the second is the cutting of shapes in the wood by the use of a sharp tool As civilizations progressed there have been constant modifications and improvements over the original two person lathe machine most importantly on the production of the rotary motion.
The production of the rotary motion therefore evolved according to the following procedures the Egyptians manual turning by hand the Romans addition of a turning bow the introduction of the pedal in the Middle Ages the use of the steam engines during the Industrial Revolution the employment of individual electric motors in the 19th and mid 20th centuries and the latest of which is the adaption of numerically controlled mechanisms in controlling the lathe machine.
For the lathe machine to function and perform its operations various important parts are integrated together These essentials parts make up the lathe machine and include the following.
This article is about the general description of how the lathe machine functions and how its design evolved over the years The first lathe machine was developed by the Egyptians and was then called the two person lathe machine There were other modifications of the lathe machine that were developed in different time periods No matter how the lathe machine may have been modified the basic.
