摘要

Fuse body is a form of munition fuse employed in defence applications. Machining of fuse body is a difficult process in industries as numerous operations are included in its production process. The present research introduces development of a novel multi-parts holding fixture specially designed to machine the fuse bodies. Fixture holds twelve parts at a time and processes simultaneously in three steps on a vertical machining centre. The special value of the fixture is that it gradually combines dense clamping with the minimum requirements of setting up the work parts. SolidWorks is used to create 3D models of fixtures and ANSYS is used to validate the model simulation. Maximum stress and deformation are found to be 17.104 MPa and 0.015575 mm respectively at the applied load of 14,200 N. Moreover, these outcomes are verified using standard design methodology. The novel stepwise fixture saves total production time per part by 23%. This resulted in 25% increase in production as compared to traditional fixtures, without sacrificing dimensional accuracy of less than ± 0.03 mm. Novel fixture design proves not only more efficient in production but also in reducing idle time, operator dependency and the complexity of handling jobs. All these enhancements make the system very applicable for improving efficiency of fuse parts machining process and beneficial to production facilities of critical defence component.
