Abstract
The milling system of pseudo simultaneous five-axis machining is discussed in this study, applied to such as multi-tasking machine with 4-axis simultaneous machining and spindle headstock milling. This novel alternative method is comparable to full 5-axis simultaneous machining and allows us to execute machining complex shape without a required equipment. Pseudo simultaneous five-axis machining is the following: During cutting at one pass, ball-end mill attached at the spindle rotates temporarily without cutting at a certain time, and then 4-axis simultaneous machining continues. VERICUT which is dedicated CNC simulation and verification software is used to customize the CAM post process. Milling experiments of the present method are carried out with simultaneous 5-axis vertical machining center(MAZAK, VARIAXIS 500-5XII) and multi-tasking machine(MAZAK, INTEGREX j-200) in our college. It is found that the pseudo simultaneous five-axis machining would be utilized for milling by using indexing 4-axis simultaneous machine.
