Paper Abstract

The efficiency of industrial quality control has greatly improved in the past decade through the application of the mini-computer and two major developments in optical systems, namely optical grating transducers and the c.w. gas laser. The paper describes a new automatic machine designed in collaboration by the SKF European Research Centre and the Cranfield Unit for Precision Engineering (CUPE), for not only gauging automotive engine cylinder bores, but also laser scanning the bore surfaces to evaluate surface quality, e.g. the presence of retained boring marks, porosity and blow hole defects and the existence of acceptable honing cross-hatch etc.. Thus, a previously labour intensive viewing type inspection process is replaced by an automatic QC system. A second automatic QC development for the automotive industry is the Horstmann-Cranfield CNC cam shaft measuring machine, which not only rapidly measures the rise errors on all lobes of a cam shaft, but also analyses and presents the derived errors of velocity, acceleration and "jerk". One such machine will provide quality audit services for a DNC manufacturing cell in the UK for high precision cam components. The cell will contain a group of new Adaptive-CNC cam grinding machines designed and developed by CUPE. These machines are "quality-adaptive" in that optical grating systems are used to ensure that irrespective of grinding wheel size, only cams of the correct profile and size are produced.
