20110251714 | APPARATUS FOR AND METHOD OF MEASURING WORKPIECE ON MACHINE TOOL - A workpiece measuring apparatus has an external module provided outside an NC device to acquire position data of one or more movable axes of a movable unit having a measuring head attached thereto. The position data of the measuring head is acquired at the same time interval as that for the distance measurement by the measuring head. The position of the workpiece is acquired by calculation from the acquired distance measurement data and the position data of the measuring head. The continuous shape of the workpiece can be measured by performing continuous measurement while moving the measuring head. Therefore, no modification or change is required such as adding a new function to the NC device. In addition, the present invention is applicable to any machine tool equipped with an NC device of any configuration, without being restricted by constraints of the NC device. | 10-13-2011 |
20120029866 | RELOCATION DETECTION METHOD AND RELOCATION DETECTION UNIT - A relocation detection unit includes: an acceleration sensor adapted to detect acceleration generated in the apparatus, an arithmetic section adapted to obtain a first calculation value by performing Nth-order integration on detected value of the acceleration sensor at a predetermined timing, wherein N is a predetermined positive integer, a correction section adapted to obtain a second calculated value by adding/subtracting a specific value to/from the first calculation value at the predetermined timing, and a detection section adapted to detect that the apparatus has been relocated if the second calculated value exceeds a preset reference value. | 02-02-2012 |
20120296449 | Positioning Control Apparatus and Machine Tool Provided Therewith - A positioning control apparatus has a moving body, a feed device having a guide mechanism for guiding the moving body in the direction of its feed axis and a drive mechanism for moving the moving body, a structural body supporting the feed device and a controller for controlling a moving position of the moving body with respect to a reference position on a machine tool by controlling the operation of the drive mechanism, and further has a calculating section calculating displacement of the feed device in the feed-axis direction with respect to the reference position caused by displacement of the structural body and a compensating section receiving the displacement data measured by the calculating section and adding modification data for eliminating the displacement to a control signal in the controller. | 11-22-2012 |
20140150533 | Method and Apparatus for Detecting Airtight State of Machine-Tool Window - Methods and apparatus for detecting machine tool window airtightness includes an airtight state detector, having a sensor detecting the pressure in a space of the window, and a judging section for determining appropriateness of the airtight state of the space based on a pressure value from the pressure sensor and outputting a judgment result. Pressure in the window space, which initially may be pressurized or pressure-reduced, is detected intermittently by the pressure sensor, and the judging section determines appropriateness of the airtight state of the window on the basis of a variation state of the detected pressure. | 06-05-2014 |

20110285499 | ELECTRONIC EQUIPMENT, AND RESTRICTION REMOVAL METHOD - Electronic equipment includes a GPS dongle for acquiring current location position information, and a PC for acquiring planned installation position information indicating a planned installation position of a machine tool previously registered with a server device which is a supplier-side device of the machine tool from the server device. The electronic equipment compares the acquired current location position information with the acquired planned installation position information, to determine whether or not the current location is within a predetermined range having the previously registered planned installation position as a base point. The electronic equipment determines, if it is determined that the current location is within the predetermined range having the planned installation position as a base point, whether or not a predetermined condition has been satisfied. The electronic equipment performs, if it is determined that the predetermined condition has been satisfied, information input processing on the machine tool, to remove activation restriction on the machine tool. In this manner, the electronic component can prevent illegal removal of activation restriction on the machine tool. | 11-24-2011 |
20120197421 | MACHINE TOOL CONTROL SYSTEM - An optimum cutting feed rate of a machine tool is calculated at the outset and a tool path as well as the optimum cutting feed rate calculated is directly output to a driving unit of the machine tool. A relative movement between the work and a tool is made to occur along the tool path at the optimum cutting feed rate for each part of the tool path. To this end, a control system includes a CL data generating unit | 08-02-2012 |
20120197424 | MACHINE TOOL, MACHINING METHOD, PROGRAM AND NC DATA GENERATION DEVICE - A work having a non-circular cross-section is machined by relative movement between the work and a tool, as the relative position and angle between the work and tool are changed at least within a plane including the cross-section of the work. In machining along a preset tool path, the difference between the relative angle at a point on the preset tool path which machining is started and that point on the preset tool path at which machining is finished is calculated. Time needed in machining along the preset tool path is equally divided by a preset number at equal time divisions, and positions on the tool path corresponding to equal time divisions are set as tool path points. When the tool moves through each point, the relative angle is continuously changed an angle corresponding to division of the difference of the relative angles by the preset number of equal time divisions (FIG. | 08-02-2012 |
