Gauges and templates are used in the modern era to make any part interchangeable and to increase mass production. Due to every time adjustment, it is impossible to take accurate readings, and making parts interchangeable takes too much time. Therefore, for mass production to make it interchangeable gauges and templates are invented.  A gauge is … Read more

Screw threads are extensively incorporated in the design of mechanical components to fasten or transmit power. Depending upon the applications, these threads differ in size, form, and quality. Thread production is of great importance for fitters because of the increasing demand for high-precision fastening devices and power transmission systems. In this chapter, we will study … Read more

The various operations are performed in a lathe machine such as follows. 1. Straight Turning The workpiece is turned straight when it is made to rotate about the lathe axis and the tool is fed parallel to the lathe axis. The straight turning produces a cylindrical surface by removing excess metal from the workpiece. It … Read more

The lathe is considered the oldest machine, that is widely being used in industries. It is said that the first screw-cutting lathe was developed by an English man named Henry Moudslay in the year 1977. Modern high-speed and heavy-duty lathes are being developed based on this machine. The primary task of a lathe is to … Read more

The assembling technique is a combination of methods used for assembling the machines, their parts, and types of equipment. The assembling is a process by which the different parts of a machine are assembled together to form a unit. It can be understood more easily as a design of assembly. The design of an assembly … Read more

The maintenance required in the plants to run the machine regularly and to keep the types of equipment safe is known as plant maintenance. So, it is important to know about the maintenance. Maintenance is an art of engineering that is developed in a manufacturing organization to keep the plant physically in good operating condition … Read more

In the present time, to make any part interchangeable and to increase mass production, it is important that a job or workpiece should be prepared according to the drawing tolerance and limit with the help of a caliper or other instruments. It is possible to prepare an accurate job but it is very time-consuming. Thus, … Read more

A metal is a solid material, which means typically hard, non-transparent, and has good electrical and thermal conductivity. Metals are generally malleable because they can be hammered permanently out of shape without breaking or cracking. These are fusible, i.e., able to be fused or melted, and ductile, i.e., able to be drawn out into thin … Read more
