Problems solved by technology

[0008] However, in the conventional example, it is automatically judged whether to move to the machining operation or the measurement operation based on the position information indicating whether the drive shaft belongs to the machining area, the cleaning area, or the measurement area. The shape measurement of the workpiece is also carried out under high ambient temperature, and the positional relationship between the measuring device and the workpiece cannot be kept fixed, so that accurate shape measurement cannot be performed

Embodiment approach

[0041] figure 1 is a plan view showing a schematic configuration of an NC machine tool 1 according to an embodiment of the present invention, figure 2 yes figure 1 Front view of the NC machine tool 1. Such as figure 1 and figure 2As shown, the NC machine tool 1 includes: NC machine tool body 10; pallet changing device 16, which is arranged near the NC machine tool body 10; cover body 2, which separates the processing area of ​​the workpiece W from the outside; not shown), the main shaft 6 and the stage 7 are relatively moved; the tool changer (not shown) is used to replace the tool installed on the main shaft 6 with a new tool; The action of the replacement device is controlled; the measurement system 40 measures the machining accuracy of the workpiece W to be processed; and the temperature adjustment member 30 is used when the workpiece W is processed to adjust the ambient temperature of the processing area in the cover body 2 .

[0068] image 3 It is a plan view showing a schematic configuration of a machine tool 1A according to Modification 1 of the embodiment of the present invention. image 3 The machine tool 1A if with figure 1 Compared with the machine tool 1 of the present invention, the difference lies in that a control unit 20A is provided instead of the control unit 20 .

[0069] If the control unit 20A is connected with figure 1 Compared with the control unit 20 of the above, the difference is that the injection operation of the fluid injection nozzle 33 is controlled so that the injection amount injected from the fluid injection nozzle 33 becomes the maximum when the machining of the workpiece W is completed.

[0070] therefore, image 3 The machine tool 1A if with figure 1 Compared with the machine tool 1, it can be cooled more rapidly (rapid cooling) until the ambient temperature reaches a specific temperature. In addition, since there is no need to provide a temperature sensor for d...

Abstract

Provided is a machine tool (1) capable of measuring the machining precision of a work (W) with high precision and greatly shortening the time required from machining to measuring the machining precision. The machining tool (1) machines the work (W) while relatively moving a tool and the work (W), and the machining tool comprises: a cover body (2) that partitions, from the outside, a machining region where the work (W) is machined; and a temperature adjusting means (30) that is used when machining the work (W) and that adjusts the atmospheric temperature in the machining region.

Description

technical field [0001] The present invention relates to a machine tool configured to measure the machining accuracy of a workpiece. Background technique [0002] Conventionally, there is known a machine tool capable of directly measuring a workpiece (processed object) by attaching a measuring device to a tool spindle or the like after all machining is completed. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2013-129036 ) discloses a machine tool in which operations ranging from ultra-precision machining and cleaning to on-machine measurement are automatically performed by a numerical controller without operator intervention. In this machine tool, the operation area of ​​the drive shaft of the processing machine is divided into processing area, cleaning area and measurement area in advance, and the position of the drive shaft is monitored by the numerical control device. When the drive shaft enters each area, it is assigned to each area. The job s...
