Patent number: 9477218Abstract: A numerical control device which controls a feed axis of a machine tool has a storage unit which divides a range of movement of the feed axis into a plurality of regions and stores a plurality of control parameters corresponding to the divided plurality of regions in advance, a position detection unit which detects a position of a feed axis at the time of machining a workpiece, a parameter selection unit which reads out control parameters corresponding to a divided region to which the detected feed axis position at the time of machining a workpiece belongs, and a servo control unit which controls the feed axis using the read control parameters. Due to this, it is possible to provide a numerical control method of a machine tool which realizes stable machining precision without regard as to the feed axis position and a numerical control device which conducts that method.Type: GrantFiled: October 26, 2011Date of Patent: October 25, 2016Assignee: Makino Milling Machine Co., Ltd.Inventors: Akira Kawana, Norio Mori, Mitsunari Oda

Patent number: 9459612Abstract: Disclosed are a movable device allowing instantaneous correction of error in a moving state and an error correction method thereof. The movable device includes a drive unit that is previously set up with an allowable error and has a moving path along which detection units are installed in a line. Precise measurements are taken in advance to obtain position data of each of the detection units. Comparison is then made by the controller between instantaneous data and corresponding comparison data. When the controller determines the instantaneous data exceed the comparison data, an instantaneous correction operation is made to make the instantaneous data not exceeding the comparison data. Acceleration or deceleration may be made by the drive unit to effect such a control that when the movable piece reaches the next detection unit, the instantaneous data do not exceed the comparison data.Type: GrantFiled: August 28, 2012Date of Patent: October 4, 2016Inventors: Yung-Kui Lu, Kee-Tai Tsai

Publication number: 20150142164Abstract: After a Z-axis on which a chamfering tool is mounted is located in a machining position for chamfering, two orthogonal axes (X- and Y-axes) perpendicular to the Z-axis are positioned to be ready for the chamfering. The Z-axis is compensated simultaneously with the X- and Y-axes in accordance with a machining path in a machining program, based on tool data, whereby the entire cutting edge of the chamfering tool can be used for each chamfering cycle. Specifically, the radius of the tool is made variable so that a chamfering area can cover the entire cutting edge of the tool.Type: ApplicationFiled: November 17, 2014Publication date: May 21, 2015Inventor: Daisuke UENISHI
