However, there are difficult ies in machining ; especially l aser g yro ti tanium alloy b racket when it has changed from small-lot manufacture to large scale manufacture , so the former fabrication technology cannot meet the modern manufacturing demand; so as to solve the problem. The new technology has been researched to improve old one according to the existing circumstances .The actual production proves that the new manufacture technology not only improve the machining precision ofl aser g yro b racket ,but also ensure the stabilization of quantity production as well. T his paper emphatically discourse dupon science researches on manufacturing ofl aser g yro ti tanium alloy b racket in the way of as follows. Firstly , according to the especial configuration and machining precision of titanium alloy bracket to establish manufacturing projects for high production ; and improve technology regulations in actual manufacturing so that increase of production . S econdly, as the full production requirement make choice of cutting tools material and cutting parameter which can reduce not only costs of production ,but also ensures machining precision . Th
