Problem statement and motivation

Die casting is a manufacturing process used for the production of large volumes of parts of light alloys, such aluminium, zinc, magnesium, lead and some copper alloys. It is a relatively low cost process, which allows for a high degree of design intricacy and provides remarkable accuracy and good surface finish. Among the finishing operations, the deburring process is a key step, whereby raised edges or small, unwanted pieces of materials attached to the part are eliminated.

Normally, cutting press machines are responsible for cutting these burrs, or even thicker parts as sprues and runners, which are formed during the injection process. Sometimes, given the complexity of the piece, the thickness and type of material, the cutting is imprecise and generates unwanted geometric deviations on the parts. As a result, it is necessary to add new operations, like inspection, review and manual deburring and sanding with abrasive tolos.

This experiment intends to provide a more advanced deburring system, by combining laser techniques, robotics and machine vision into a fully operating prototype.
