A Surface Preparation Machine for Cylindrical Mechanical Test Specimens

Аннотация

A surface preparation machine which can provide a controlled surface condition for mechanical test specimens has been developed. The apparatus includes mechanical and electrical systems that have been designed with a simplified manufacturing processes employing extensive additive manufacturing. Experiments were carried out to evaluate the capability and repeatability of this machine. It has been shown that the machine provides an effective methodology to prepare cylindrical specimens with a high level of automation. Specifically, the machine provides the ability to control four active axes, grinding time and speeds as well as levels of lubrication beyond what grinding media employed. The application of the machine on aluminum specimens is described.
