Patent number: 7755316Abstract: A movement control apparatus for a moving member, includes: a drive unit that moves a moving member by rapid traverse on a first axis and a second axis intersecting the first axis, and overlaps the rapid traverse movements in the two axis directions to thereby allow the moving member to move around the periphery of a given area; a reference arc setting unit that sets a reference arc inscribed in the first and second axes; a timing setting unit that sets an overlap movement start timing for the rapid traverse of the moving member based on the reference arc when switching the moving member from the first axis to the second axis; and a control unit that controls the operation of the drive unit to move the moving member at a timing set by the timing setting unit.Type: GrantFiled: June 29, 2007Date of Patent: July 13, 2010Assignee: Star Micronics Co., Ltd.Inventors: Satoru Ozawa, Noriyuki Yazaki

Publication number: 20090271017Abstract: In a machine tool which executes a plurality of programs simultaneously to perform machining, whether or not a precision machining operation period exists in each of the programs is analyzed before machining. If the precision machining operation period exists as a result of the analysis, the start timing and end timing of an ordered precision machining is recognized. Also, at least one of the speed, acceleration, and jerk of a general operation from start timing to end timing in a program for which the precision machining operation period is not specified is lowered. Accordingly, it is possible to provide a machine tool and its program conversion method, capable of performing precision machining with high precision without receiving an adverse effect from other operations, and capable of obtaining good machining efficiency.Type: ApplicationFiled: December 25, 2006Publication date: October 29, 2009Applicant: STAR MICRONICS CO., LTD.Inventors: Noriyuki Yazaki, Satoru Ozawa, Tetsuya Sugiyama, Akihide Takeshita, Takehisa Kajiyama, Hideyuki Yagi

Publication number: 20090036280Abstract: A movement control apparatus for a machine tool includes a travel boundary arc setting unit and a control unit. The machine tool includes a tool post that supports plurality of tools, and a drive unit adapted to relatively move at least one of the tool post and the workpiece in a direction of a first axis and in a direction of a second axis that intersects the first axis to change a tool. The travel boundary arc setting unit sets an arc so that the arc is inscribed in the first and the second axes and an axial center of the workpiece passes through a position distant from a corner portion of a tool by a radius of the workpiece. The control unit is adapted to control the drive unit so that the workpiece travels along a travel locus outside the arc while changing a tool.Type: ApplicationFiled: July 30, 2008Publication date: February 5, 2009Applicant: Star Micronics Co., Ltd.Inventor: Noriyuki Yazaki
