Automated Alignment System

angle detection for mintingIdentifies and corrects misalignment errors that operators and machine grinders tend to miss, meaning faster production times and a more confident manufacturing process.

How it Works

The Angle Detection System meets coining challenges by pairing with a client’s existing CNC Machine to assist in identifying accurate angles on the die before keying. There is only a small margin of error allowed for the stamping process, and the dies must be orientated correctly to ensure that there are no defects produced on the final product. Our system is capable of identifying and correcting those misalignment errors that the operator or grinder may not be successful in catching.

The unit illuminates the shiny die face and captures high-resolution images that are sent to the PC. Coin die angles are calculated via Artemis Vision’s proprietary software which then sends motion commands to the grinder to align the die. The system utilizes only industry-leading hardware for reliability, high dynamic range feature, and GigE interface capabilities. Additional hardware includes a machine vision lens, lens extender, and light diffuser.

Customizable features allow operators to set angular points on the coin die models with high accuracy for more consistent keying every time. The intuitive program also provides feedback on the images of expected angles, reported angles, and angle errors, and can retrieve previously saved models to save time.

A Challenge Resolved

Coin mints and manufacturers alike follow a detailed and highly accurate coining process to produce a high volume of new coins. The process involves using a CNC Machine Grinder to key coin dies that are used later during the stamping procedure. The CNC Machine must grind the die with high angular precision to ensure that it can be inserted with accuracy into the press. Mints can stand to lose a lot of time, money and efforts on consequent waste from improper coin stamping and must ultimately produce consistent coins with consistent quality.

Artemis Vision considered these production issues asked critical questions to determine the most successful vision solution.
