MACHINING METHOD, PROGRAM, MACHINING-PROGRAM GENERATING PROGRAM AND MACHINING APPARATUS OF PRESS DIE
Publication number: 20090133461Abstract: A machining method of a press die having a pierce cutter and a secondary relief-clearance area recessed inward relative to a profile of the pierce cutter is provided. A plunge cutting tool having a tool body and at least one edge portion provided on an outer circumference of an end of the tool body is used, the edge portion being protruding from the outer circumference of the tool body and being capable of carving while rotating around an axis of the tool body and moving in an axial direction of the tool body. While rotating the plunge cutting tool with an axis of the tool body being approximately parallel to a surface of the pierce cutter, the plunge cutting tool is relatively moved along the profile of the pierce cutter. The plunge cutting tool is also relatively moved in the axial direction of the tool body along the shape of the pierce cutter and the secondary relief-clearance area in a piercing direction each time the plunge cutting tool is relatively moved by a predetermined pitch.Type: ApplicationFiled: November 24, 2008Publication date: May 28, 2009Applicant: TOSHIBA KIKAI KABUSHIKI KAISHAInventors: KOUICHI KATOH, Takamasa Itoh, Yoshiaki Mikami, Norihiro Miyazawa, Hirofumi Shinohara -
Publication number: 20090110505Abstract: The invention relates to a program-controlled milling and drilling machine comprising a machine column, a machining unit comprising a milling head and being movable along at least one coordinate axis at the front of the machine column, a machine bed disposed in front of the machine column, a work carrier movable on the machine bed along another coordinate axis, and a pallet exchanger arranged at the free end portion of the machine bed, having two spaced apart pallet holders and a rotating and lifting mechanism on a joint load-bearing structure. According to the invention, the load-bearing structure of the pallet exchanger is laterally arranged next to the machine bed and has a dimensionally stable and sturdy transverse arm extending across the machine bed and supporting the rotating mechanism, the lifting mechanism in the load-bearing structure laterally arranged next to the machine bed being arranged in a manner so as to protect against dirt by a splashboard.Type: ApplicationFiled: October 2, 2008Publication date: April 30, 2009Applicant: DECKEL MAHO PFRONTEN GMBHInventor: Robert Jung

Publication number: 20090020509Abstract: An apparatus and method for hybrid machining a workpiece is disclosed. The workpiece is powered as an anode, a cutter is powered as a cathode and a cutting fluid or coolant is circulated therebetween. The cutter is made of a conductive material and a non-conductive abrasive material. The hybrid machine performs a roughing pass machining operation in which material is removed from the workpiece at a relatively high rate using a high-speed electro-erosion (HSEE) process. Then, the hybrid machine performs a finish pass machining operation in which material is removed from the workpiece using precision electro-grinding (PEG) process at a different differential electrical potential and/or flushing rate than the roughing pass machining operation to provide a smooth finish without thermal effects on the workpiece.Type: ApplicationFiled: July 17, 2007Publication date: January 22, 2009Applicant: GENERAL ELECTRIC COMPANYInventors: Andrew Lee Trimmer, Nicholas Joseph Kray, Joshua Leigh Miller, Michael Scott Lamphere, Bin Wei
