Specifications from the computer program can then be used to electronically develop drawings for the required tools and dies. The electronic drawings are then processed by a computer-aided manufacturing program to calculate cutting tool paths and the sequence of operations. Programs can also be electronically stored and adapted for future use. This saves time and increases worker productivity. These areas are quieter than the production floor because there are fewer machines in use at one time.
Machines have guards and shields that minimize the exposure of workers to moving parts.
Tool and die makers must follow safety rules and wear protective equipment, such as safety glasses to shield against bits of flying metal, earplugs to protect against noise, and gloves and masks to reduce exposure to hazardous lubricants and cleaners. These workers also need stamina, as they often spend much of the day on their feet and may do moderately heavy lifting. Companies employing tool and die makers traditionally operate one shift per day. However, as the cost of new machinery and technology has increased, many employers now have more than one shift. Overtime and weekend work are common, especially during peak production periods.
