Description

  The present invention relates to a workpiece reference position measuring device for measuring a workpiece reference position of a workpiece to be processed by a machine tool outside the machine tool, and a machining / measurement system using the measuring device, in particular. The present invention relates to a processing reference position measuring apparatus and processing / measurement system for a workpiece by external setup used for measurement before processing.

When machining with a machine tool equipped with a pallet changer that can accommodate multiple workpieces, after moving the workpiece to the machine tool with the pallet changer and fixing the workpiece before machining inside the machine tool The workpiece was measured to determine the machining reference position, and machining was performed.
However, in the above method, even if a plurality of workpieces are mounted on the pallet changer, the workpiece must be measured for each machining operation in one machine tool, and work efficiency is improved. There was a problem of being bad.
In particular, in the case of multi-product small-volume production or individual production, even if there are a plurality of workpieces that can be mounted on the pallet changer, the machining reference position must be measured for each workpiece.
In addition, when confirming the machining reference position again during machining, the work must be interrupted until the workpiece heated by cutting cools down, and delays until machining of other workpieces that have been placed on the pallet changer. There was a problem of letting.

2. Description of the Related Art Conventionally, there has been disclosed a device that is disposed near or around a machine tool and measures the size and shape of a workpiece after machining, or a machine tool provided with this device (Patent Documents 1 to 3).
Further, there is known a workpiece inspection apparatus that can inspect immediately after processing by making the workpiece support means of the workpiece positioning apparatus common to the workpiece support means of the workpiece inspection apparatus (Patent Document 4).

It was difficult to measure with the same accuracy.
