A new slant on diagonal laser testing TJ. Morris Cincinnati Machine U.K. Ltd., Birmingham, England Abstract In the early 1990s the Americans introduced diagonal laser tests as a quick method for evaluating the volumetric accuracy of machine tools. More recently, ISO have started preparing a new standard based on this document. This paper examines what can be achieved with this type of test, and what advantages can be gained by carrying out the proposed additional face diagonal measurements in a three-dimensional domain. Of particular interest is the potential ability for checking squareness measurements on large machines. 1 Different approaches to the measurement of accuracy When a customer asks a manufacturer how accurate his machine tool will be, what he really wants to know is, how accurately will the machine produce his components. For this, all he needs to know is how accurately the tool to work- piece relationship can be maintained. The manufacturer will probably evade
