These fixtures, which are used for holding the components for performing mechanical operations, are known as mechanical assembly fixtures.
What are jigs and fixtures?
In order to demystify the confusion in jig vs fixture, this article will introduce the tools in terms of their types, differences, and uses.
After going through the article, you will understand the difference between both tools and how you can use them for a smoother operation.
12 Difference Between Jig And Fixture (With Advantages & Disadvantages)
Then the , which include a variety of clamps including jig and fixture clamps are mounted on the fixture plate.
An automobile assembly line, for instance, is not possible without the hardworking fixtures that secure and guide cars through the welding and assembly process.
The jig is used for guiding the like a drill bit , and for doing so, jigs have components like a bush, which comes in contact with the cutting tool.
Once machining at both the stations is over, the fixture is indexed through 180 degrees so that the first component is shifted to the second station for the second operation and the finished component to the first station.
Let's see some advantages of Jigs and fixtures: It eliminates the setting time required before machining. It increases the machining accuracy and also increases production capacity. Requires less skilled operation. They reduce the production cost. Increases machine and labor utilization. They simplify the work handling.
Jigs are commonly used in drilling, boring, reaming and tapping, while fixtures are adopted for milling, slotting, shaping, turning and planning. 6. Cost Jigs are usually more expensive than fixtures. 7. Design The construction of the jig is often designed more complex while the fixture designs are simpler. 8. Whether contact with cutting tool
Jigs and fixtures allow unskilled or semi-skilled machine operators to set up the workpieces reducing labor cost. > Cost Reduction Higher production, reduced scrap, easy assembly and savings in labor cost result in an ultimate reduction in unit cost. Jig and Fixture Design Basics
Other differences between jigs and fixture include: Jigs are often fairly lightweight, while fixtures must be heavy enough to provide stability Jigs can be held in place manually, while fixtures are mechanically secured to the table Jigs may require more intricate design, while fixtures are typically more straightforward
The jig and fixture generally function in securing the workpiece and machine parts. However, there is a difference between both. With the fixture, the tool does not move when the workpiece moves. This is not so with the jigs where the tool moves. Depending on the types of jigs and fixtures, you might need to clamp also.
