Abstract
A system for removing a heat check feature on an aluminum casting formed by a high pressure die casting process is provided. The system includes a laser source, a robotic arm, and a heat check sensor. The heat check sensor develops a surface profile of at least part of the casting and transmits heat check feature information to the laser source to project the beam of laser light thereon. The projection of the beam of laser light can be varied in time and power, which can depend on surface profile information obtained from the sensor. Once at least a portion of the heat check feature is removed, the casting is placed against another part such that the joint interface is primarily the portion where the heat checking has been removed. Self-piercing rivets are then driven into the casting and the part to permanently join them together.
