Computerized Ultrasonic Gauging

Abstract

A high precision ultrasonic gauging system has been designed and implemented for use on a CNC lathe. The system uses a PC along with a number of plug-in cards to generate, receive, and process ultrasonic signals. The system has been reliably used both during and after machining operations. It is capable of simultaneous measurement of wall thickness, runout, outer diameter radius, inner diameter radius, and concentricity of the inner diameter and outer diameter. Data densities of 2000 measurements per revolution of all parameters can be achieved. Data can be acquired at lathe spindle speeds that keep the outside part surface moving at less than about 2000 surface feet per minute. A real time, pseudo color, image of the wall thickness is provided during operation. The system can receive setup and operational instructions from the lathe CNC so that operation can be accomplished with very little operator involvement.
