Principles of jig and tool design
Nodular cast iron is as hardened to RC When a product is to be tooled up urgently, the services of a Contract Tool Drawing Office is often obtained in order to avoid the temporary employment of designers and draughtsmen; these offices charge a fee for the tooling up of a complete component, and to ensure interchangeability of components. Jigs and fixtures are specially designed so that large and fixtures are specially designed so that large numbers of components ponents can be machined or numbers of components can be machined or assembled identical.
