The Importance And Precision Of Tool Making
For most of us these words may bring to mind common objects that we might use at home to complete several everyday tasks like hanging a picture or installing a screw. It actually involves a very precise form of machining that requires some detailed training and often several years of experience. Tool Making or machining is likely to include drilling, turning, milling, shaping, boring, planing, sawing, boring, and broaching with the ability to follow very detailed plans to completion.
The business itself may often be referred to as a tool and die firm, with the die be a representation for die cast metal. Recently used techniques have become even more advanced to include water jet cutting, laser cutting, and electrical discharge machining. Many of the same techniques used to do this work are the same as the techniques that are used in professional woodworking.
The process consists of two types of cuts including roughing cuts and finishing cuts. The roughing cuts are in the beginning and will remove the majority of unnecessary metal away to begin the desired shape. Finishing cuts are all of the remaining cuts made to complete the project including the surfacing.
Shops are usually specifically designed for this type of work and rooms are designated by specialty. Most pieces are extremely detailed and require either blueprints or some type of engineered drawings to follow. Large businesses may contain smaller internal machine shops of their own to do the required work necessary on site.
Motion is required between the actual tool and work in order to create a machining operation. Cutting speed is considered to be the primary motion, combined with the slower motion of feeding the metal. Speed, feed, and depth together make up what we call the cutting conditions with relation to the machining process.
