Abstract:According to structural characteristics of dual-effect strong side-cut window bit (hereinafter referred to as window bit) and the theory of metal cutting and the rule of teeth arrangement of window bit, a cutting mechanical model of window bit cutting teeth is established, window bit geometric equations deduced and the solution of the cutter cutting mechanical model completed; finally, the casing window experiment is conducted with the dual-effect strong side-cut window bit developed to verify the accuracy of … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
