An Inertial Sensor for Parts Inspection

This paper describes the development of a sensor which performs parts inspection by measuring the inertial properties of the part. The sensor comprises a platform supported on a column which isjxed to a rigid base. The part under inspection is attached to the plafform toform a single body. By measuring the static dejlections of the column and the natural Pequency of vibration ofthe system, it is possible to determine the spatial location ofthe centre of mass of the part. Inspection is usually required to ensure that a part is machined according to its specification. It often involves measuring various attributes of the part under inspection and comparing the measured values against those specified. The attributes being measured may include the size, shape, mass, locations and sizes of drilled holes and locations and sizes of milled slots of the part. Human inspection, which measures those attributes manually using vernier callipers, micrometers, balances and gauges, is ineffective and...
