Abstract : The pressing or straightening of gun tubes is a difficult and tedious operation. There are no set guidelines that can be applied to assist the operator in pressing a gun tube. It is impossible to predict how much each individual gun tube will have to be pressed in order to straighten it to acceptable limits. Due to these conditions it introduces a measure of tension or strain on the operator. Any input that would give greater control which would induce more operator confidence would be of benefit to both operator efficiency and process improvement. The application of digital readout equipment for pressing gun tubes has proved the feasibility of the system as a superior and more accurate and reliable process than current methods. Without question, once learned and understood, the system will show itself to be very basic, simple to operate and easily adaptable. The system requires little care and with proper attention it should provide long and reliable service. The test and evaluation period, during which fifty-three (53) gun tubes of different sizes were successfully pressed without difficulty, has proven the system adaptable to production application.
