How the EDM Process Works

Home » Manufacturing » EDM » How the EDM Process Works

The whole EDM process is designed very well. Once the process starts, many parts can be made that are accurate and reliably made. For example, car makers can have car parts that are consistently made the right way so there would be less defects. Fewer defects mean fewer returns. This saves on production costs in the end. The manufacturing process works like this:

• First relax the surface-finish and get it ready for the part. This way of doing it keeps the machine from making more passes than is necessary. It also lets the machine create more parts with the right amount of excess metal remaining.
• At this point you now need to prepare the part so that the amount of stock that is removed is small. This can be done by using a standard machine technique to remove the stock, after which the rest can be removed by EDM. This helps reduce the amount of time the part is in the machine.
• When setting up the parts to be prepared, the manufacturer should consider buying a device that will hold many parts stacked together so as to burn off the excess metal on more at one time. This way more work gets done in less time.
• Another factor the manufacturer should consider when working with parts is the hole that needs to be made. In order to get the best spark for the burn off needed, a through hole should be created instead of a blind hole as it will permit easier electrical flow through the machine.
