Tool And Die Maker Coursebook

Traditionally, working from engineering drawings, tool makers marked out the design on the raw material (usually metal or wood), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, jig borers, and jig grinders) and hand tools (such as files). Many tool makers now use computer-aided design, computer-aided manufacturing and CNC machine tools to perform these tasks. Tool making typically means making tooling used to produce products. Common tools include metal forming rolls, lathe bits, milling cutters, and form tools. Tool making may also include precision fixturing or machine tools used to manufacture, hold, or test products during their fabrication. Due to the unique nature of a tool maker's work, it is often necessary to fabricate custom tools or modify standard tools. Die making is a subgenre of tool making that focuses on making and maintaining dies. This often includes making punches, dies, steel rule dies, and die sets. Precision is key in die making; punches and dies must maintain proper clearance to produce parts accurately, and it is often necessary to have die sets machined with tolerances of less than one thousandth of an inch. The subject matter has been dealt with utmost care, in tune with the revised curriculum and pedagogic principles. It is hoped that this book will enable the teacher to provide suitable learning activities for effective learning.
