Question 12

TEMPLATE JIG:
A template jig is primarily used for guiding the cutting tool during machining operations, such as drilling, milling, or routing. It provides a template or pattern for the tool to follow.

Answer 12

Function

Question 13

A template jig consists of a template or pattern made from hard material (e.g., metal, plastic, or wood) with the desired shape or pattern cut or formed into it. The workpiece is placed beneath the template, and the cutting tool follows the contours of the template to create the desired features on the workpiece.

Answer 13

Design of template Jig

Question 14

Template jigs are often used for creating complex or irregular shapes on workpieces. They are commonly employed in woodworking, metalworking, and industries where precise and custom shapes are required.

Answer 14

Application of Template Jig

Question 15

Template jigs are less versatile than plate jigs because they are designed for specific shapes and are not easily adjustable for different workpieces or machining operations.

Answer 15

Versatility of template jig

Question 16

Template jigs are less versatile than plate jigs because they are designed for specific shapes and are not easily adjustable for different workpieces or machining operations.

Answer 16

Versatility of template jig

Question 17

A plate jig, also known as a fixture plate or machining fixture, is designed to hold and secure workpieces in a specific position for machining operations. It provides support, alignment, and clamping for the workpiece.

Answer 17

Function of plate jig

Question 18

A plate jig typically consists of a flat, rigid plate with various fixtures, clamps, and locating pins. It allows for the precise positioning of the workpiece on the plate to ensure accurate machining. Plate jigs are more versatile than template jigs because they can be adapted to hold different workpieces and accommodate various machining operations.

Answer 18

Design of plate jig

Question 19

Plate jigs are commonly used in manufacturing and machining processes where high precision and repeatability are required. They are suitable for operations such as drilling, milling, grinding, and assembly.

Answer 19

Application of plate jig

Question 20

Plate jigs can be easily adjusted or modified to accommodate different workpiece sizes, shapes, and machining requirements. This makes them ideal for mass production and batch machining.

Answer 20

Adjustability of plate jig
