Conclusion

The team has designed a fixture that is able to hold the force dynamometer and the ultrasonic transducer on the lathe machine replacing the conventional tool post. The team started their designing by selecting among various alternatives for thickness, material type and design. After performing computational analysis, the team decided to select the thickness of 20 mm, steel 1045 as material and a modified design for the fixture. The team also performed experiment using the designed fixtures for both conventional and ultrasonically assisted machining. The results of experimentation showed that ultrasonically assisted machining resulted in 30-40% drop in cutting forces for various cases.
