摘要： This invention relates to a process for automatically measuring the Brinell Hardness of a casting for the purpose of creating data for use in making an accept/reject decision. Process includes the steps of preparing a casting and positioning the casting on retention means positioned on a conveyor. A surface of the casting is selected for testing and this first surface is subjected to a first surface preparation step which consists of an abrasive grinding and/or machining to remove any irregularities in this surface. A second surface preparation step is then performed which comprises applying a contrast enhancing material to at least a portion of this preselected surface. Brinell Hardness testing apparatus is then used to test the casting for hardness and is then fed into appropriate means either human or mechanical for making an accept/reject decision as to the suitability of the casting for its intended use.
