Chip-breakage control is a crucial factor in all automated manufacturing processes. General Electric, a leader in the aircraft engine industry, currently experiences a significant chip control problem with their specially developed titanium alloy, Ti-17, which is used in blisk production for many military applications. The objective of this project was to determine if machining parameters and tool selection could be optimized to reduce Ti-17 chip length to a controllable size for GEAE production efficiency. Shop tests using a numerically controlled (NC) lathe were executed by varying the insert style and the critical machining parameters. The test results yielded several improved chip samples and provide some guidelines for machining process design.
