introduction to Jigs and fixtures

Introduction

Interchangeability to facilitate easy assembly along with cost savings are the most important factors in the successful implementation of a mass production. Easy and fast positioning work is important for precise operation on Mass production methods.

Two key manufacturing tools that help make precisely reproducible and interchangeable parts precisely are the Jigs and the fixtures. The jigs and fixtures are specially designed that can machine or assemble large numbers of components and easily assure the manufacturer that they can be easily replaced or interchanged any of components.

JIGS

Jigs are tools that help the machine hold and work as a maintainer, support and fix the components, and guide the cutter through various operations. Jigs are made of hard metal bushes and are a type of tool that both help control the location and help guide and move another tool.

In fact, the main reason for the production and use of a tool called a jig in machine tools is to create repeatability, and to increase the accuracy and speed of replacement of parts to produce different products. Jigs do both job-keeping and tool-handling.

When a key is duplicated, we have an example of a jig that is originally used as a jig and the newly created key can be used in any other path that may be similar to the previous one.

FIXTURES

The fixture, as its name implies, is a tool that holds and supports a set of work to perform a series or a particular task, but unlike the jigs, does not guide the cutting tool. The fixture actually provides the user with a reference work surface or a device. Given that the fixtures are each designed to fit a particular part or shape, it can be said that the fixtures are very unique.

In essence, the main purpose of installing and using fixtures on a device for a series of specific operations or some industrial process is to maintain a workpiece. This differentiates jigs with fixtures, because jigs in addition to fixing and holding the workpiece also guide the working tool to the correct position.
