摘要： A method for properly locating a flexible fixture on a CNC machine comprises probing a plurality of locators on a flexible fixture to determine a locator position on a coordinate system for the CNC machine. The position for each of the plurality of locators is analyzed to determine if all of the plurality of locators are within a predetermined offset limit from a nominal position. A controller is programmed with an offset compensation amount based upon the probed position for each locator when each of the plurality of locators is within the predetermined offset limit. The locator positions are adjusted if one of the probed locations is not within the predetermined offset limit. The CNC probing programs are generated by a computer language to accommodate various fixture configurations.

摘要： In a transfer device for workpiece carriers (18), with a number of segments (10, 10′, 10″) in which a control unit (14, 14′, 14″) respectively activates a linear motor (12, 12′, 12″), in a phase of the transfer of the workpiece carrier (18) from a first segment (10) to a neighbouring segment (10′) synchronization of the linear motors (12, 12″) is no longer effected on the basis of control commands of a central controller but instead the control unit (14) of the first segment (10) makes itself the master (S18) and subjugates the control unit (14′) of the neighbouring segment (10′) as the slave (S20). A position measuring device (22, 24) makes it possible for the master control unit (14) to carry out speed control for the workpiece carrier (18). The control unit (14′) receives information on the commutation angle and the actual force value and can therefore issue the control commands to the associated linear motor (12′) for the control process.

摘要： Spindle inclination detectors (41A, 41B) are equipped in columns (32A, 32B) of a portal bridge (24) of a machine tool (21). Each spindle inclination detector includes: a string (43) which hangs vertically with an upper end fixed to the column (reinforcement (32b)) and a lower end attached to a weight (45); a gap sensor (44) which is attached to the string to measure a distance to a front face plate (32a) of the column; and an oil damper (46). Moreover, a spindle inclination correction controller provided to the machine tool controls a Peltier device (42A, 42B) attached to a rear face plate (32d) of the column, on a basis of an average distance measured by the gap sensor, and thus corrects an inclination of a spindle (28) due to the thermal deformation of the column by correcting thermal deformation of the column.

摘要： In the machine tool (10) pertaining to the present invention, an imaging device (33) takes an image of a tool (20) being moved in the feeding direction. Contour lines (51) are identified by means of the plurality of sets of image data generated from imaging. The movement trajectory (52) and the central axis (53) of the tool (20) are identified on the basis of the contour lines (51). When the movement trajectory (52) and the central axis (53) are offset, said offset can be used to correct the positioning of the tool (20) with the machine tool (10). As a result, the processing accuracy of a workpiece improves. Moreover, when the dimensions of a tool (20) that has a tilted posture are measured, it is possible to determine the actual tool diameter or the actual blade position in the tilted posture. The aforementioned blade position and tool diameter can be used to correct the positioning of the machine tool (10). Thus, the processing accuracy of the workpiece improves even more.
