The templates and accessories are special tools used in the manufacture of components to locate and hold the workpieces in the correct alignment and orientation during machining operations. Often used instead of each other, the primary purposes of the templates and accessories are in providing repeatability, accuracy and interchangeability in the manufacture of products while sustaining the work at a fixed location.
The advantages are as follows:
Productivity
Elimination of individual marking, positioning, and frequent verification allows templates and accessories to reduce operating time, during which productivity and efficiency will increase. The high stiffness of fastening also produces an increase in speed, feed and depth of cut.
Cost reduction
Due to higher productivity, the rate of production increases. Along with the reduction of scrap, easy assembly of jigs and accessories as well as savings in labor costs, the unit cost will be reduced later as well.
Interchangeability and Quality
To facilitate the mass production of components without the need for a selective assembly, jigs and accessories fulfill their functions with a high degree of precision and uniform quality. Along with a competitive cost, all similar components are interchangeable.
Skill reduction
As the process of locating and securing workpieces is simplified, it is no longer necessary to employ skilled workers to operate the insoles and accessories. With the guide elements of the tool that guarantee the correct positioning of the tools with respect to the work pieces, the templates and the accessories help to save labor costs.
