摘要： A thermal displacement state (target thermal displacement state) in which thermal displacement of a machine tool is saturated when the machine tool is operated based on a machining program is previously stored, and a warm-up operation pattern of a motor is determined so as to approach the target thermal displacement state. The motor is driven based on the warm-up operation pattern and the warm-up operation of the motor is stopped if the thermal displacement state of the machine tool is within a predetermined range.

摘要： A device is provided for correcting the position of at least one element of a machine tool, in particular a milling machine, in which at least one compensating element is disposed between a machine element and an element whose position is to be corrected. The compensating element is adjustable by an actuating distance such that, as a result of the actuation of the compensating element, the element is pivotable about a pivot axis at a joint between the machine element and the element of which the position is to be corrected which ensures the pivoting movement about the pivot axis.

摘要： In a thermal displacement compensating device and a thermal displacement compensating method for a machine tool, a block temperature obtaining section obtains temperatures of respective blocks based on temperature information detected by temperature sensors wherein temperatures in each of the respective blocks into which a column is divided to be pluralized are defined as a uniform value. An FEM analysis section performs a structural analysis by a finite element method based on the temperatures of the respective blocks obtained by the block temperature obtaining section and infers thermal displacement amounts of the column. A compensation value calculation section calculates a compensation value for a machining command position based on the thermal displacement amounts of the column inferred by the FEM analysis section. A compensation section compensates the machining command position by the compensation value obtained by the compensation value calculation section.

摘要： The turning machine according to the present invention includes a displacement sensor (200) which measures a distance between an immobile reference point and a position of variable point which reflects the positional displacement of the tool, the immobile reference point being able to determine a relative positional correlation relating to a variable position of tools with the progress of machining of the workpiece (W) by the tool (421). In drawings the reference point is set up in the guide bush (90). And based on the measured result by the displacement sensor, the tool is moved so that the center height of the tool and the center line of the workpiece satisfy relatively the predetermined positional correlation. Accordingly, the center height deviation amount due to heat deformation and the like is corrected.

摘要： A machine tool including a system for adjusting the position of a portion of the tool based on thermally induced dimensional change. A linear voltage to distance transducer (LVDT), or a hall effect linear transducer, is mounted at the “floating” end of the ball screw or other machine component of the machine tool to directly sense the thermal expansion of the screw or component. The LVDT includes a slug portion which is received in a coil. The slug is affixed to the floating end of the screw or component and the coil is affixed to the bearing block in which the screw or component is rotatably supported. Thermal expansion of the screw or component causes the slug to move axially within the coil, in turn causing the coil to produce an electrical signal with a varying voltage proportional to the change in position of the slug within the coil.

摘要： A machine for machining a workpiece with at least one revolving or rotating tool has a work spindle with a shaft (5), whose temperature is monitored by means of at least one temperature sensor (26). The temperature sensor is detected in contactless fashion. The sensor (26) is preferably a radiation-sensitive sensor, which detects the temperature radiation output by the shaft (5). In triggering the positioning drive mechanisms, the control unit (35) of the machine (1) takes into account the temperature expansions of the shaft (5) that result from the temperature changes in the shaft. The positioning drive mechanisms serve to position a tool (6), carried by the shaft (5), relative to the workpiece (2). A machining precision is thus achieved that is independent of the temperature and temperature changes of the machine (1) overall, of temperature changes in the coolant-lubricant, and of temperature changes in the tool (6) and the shaft (5), that can all be caused by the power converted at the machining site.

摘要： A measurement and compensation system for thermal errors in a machine tool is disclosed. A module is provided to compensate thermal errors of the machine tool. The module comprises an operating part, a data bank, an analog to digital converter, a counter and a digital input/output part. The data bank stores in all the coefficients applied to a thermal error modeling equation which governs a relation between temperatures and thermal errors at various operating conditions. The operating part determines all the coefficients of the thermal error modeling equation which are stored in the data bank and calculates the thermal errors corresponding to the temperatures of a plurality of the thermocouples by the temperatures of a plurality of thermocouples inputted from the A/D converter and the positional coordinates of the bed inputted from the counter. Then, digital data of the calculated thermal errors are inputted into the digital input/output part and the digital input/output part converts the digital data to digital signal to input the digital signals into the controller. A controller orders the machine tool to compensate the thermal errors at the positional coordinates of the bed and the feed of the spindle. Accordingly, since the machine tool compensates the thermal errors in advance, the machine tool processes precisely workpieces in spite of the occurrence of the thermal errors.
