چکیده انگلیسی:
A turn-milling machine, which is a device having two spindles that rotate a tool and workpiece, can
be used to fabricate various shapes by cutting. However, little progress has been made in microcutting
using a turn-milling machine. Therefore, a micro turn-milling machine designed especially for microtools
was developed and used to fabricate micropins with various cross sections. Cemented tungsten carbide
microtools, which are useful both as a milling cutter and as a turning tool, were processed by electrical
discharge machining and employed for microcutting. As a result, various micropins were successfully
fabricated, including not only cylindrical pins but also those with cross sections having square, triangle,
and cross shapes. These noncylindrical micropins have the smallest reported cross-section dimensions
for pins fabricated by cutting to the best of our knowledge. Furthermore, cutting characteristics such as
the machined shape and surface quality were investigated, which showed that better micropin shapes
were obtained by up-cut turn-milling than by down-cut turn-milling or by turning. In contrast, turning
was superior to turn-milling in terms of the surface quality.
