DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a measuring device, and more particularly to a control device for a measuring device for performing NC control of a measuring operation of a three-dimensional measuring device.

[0002]

2. Description of the Related Art When performing NC control on a measuring operation of a coordinate measuring machine, a measuring operation procedure is created in advance by a CAD / CAM system, and a command indicating the measuring operation procedure is written in a common language such as DMIS. To record on a recording medium such as an FD. When operating the CMM in accordance with the measurement operation procedure, first, the common language recorded on the recording medium is collectively converted (translated) into a language for the CMM, and the converted language is The information is temporarily recorded on another recording medium. Next, the recording medium on which the converted language is recorded is set in the computer of the CMM. Thus, measurement preparation is completed.

Then, when the CMM is operated, the computer controls the measuring operation of the CMM based on the language for the CMM read out from the recording medium, and obtains the information obtained at that time. The measurement result data is recorded on a recording medium in a language for a coordinate measuring machine. When confirming the measurement result data, the recording medium on which the measurement result data is recorded is taken out from the CMM, and this language is converted (translated) to a common language and transferred to another recording medium. After recording, this recording medium is set on the CAD / CAM system side. Thereby, the measurement result data can be confirmed on the CAD / CAM system.

[0004]

However, in the conventional CMM, the measurement program by the CMM and the translation program for converting to a common language are separately executed separately, so that the translated common Language cannot be converted to CNC procedure in real time to measure,
There is a disadvantage that the operation is troublesome.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a control device for a measuring instrument which can be easily operated by executing a measurement program and a translation program in real time. I do.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a preferred embodiment of a control device for a measuring instrument according to the present invention. FIG. 1 shows a control device for a measuring instrument according to the present embodiment.
FIG. 4 is a perspective view of a C-controlled bridge gate movable type coordinate measuring machine. The main body 12 of the coordinate measuring machine 10 shown in FIG.
A pair of Y carriages 14, 14 are provided movably in the Y axis direction. Also, a pair of Y carriages 14, 14
Are connected by an X guide 16 and the X guide 1
6 is provided with an X carriage 18 movable in the X-axis direction. Further, a probe mounting shaft 22 that is movable in the Z-axis direction via a Z guide 20 is provided on the X carriage 18, and a probe 26 is mounted on the lower end of the probe mounting shaft 22. Thereby, the probe 26
Since it can move in three X, Y, and Z axes,
By detecting the position of the measurement point of the work (not shown) fixed on the table 28 with the probe 26, the shape of the work can be measured.

In the vicinity of the main body 12 of the coordinate measuring machine 10,
A control device 30 for a coordinate measuring machine is installed. The control device 30 performs CNC control of the measurement operation of the probe 26, and includes an LCD display panel 31, a touch panel 32, a joystick 33, and an FD drive 34.
It has. Further, the control device 30 is equipped with a measurement program including a DMIS [I / F] program 36 and a CMM measurement program 38 shown in FIG.

Next, a CNC control method using a measurement program of the control device 30 will be described with reference to the flowcharts shown in FIGS. In FIG. 2, a measurement operation procedure by the coordinate measuring machine 10 is created in advance by the CAD / CAM system 40, and a command file 42 indicating the measurement operation procedure is recorded on the FD or HD by a DMIS command (common language). You.

Next, when operating the coordinate measuring machine 10 in accordance with the measuring operation procedure, the FD is set in the FD drive 34 of the control device 30 shown in FIG. Thus, measurement preparation is completed. In addition, not only FD but HD
But it is good. Next, when the control device 30 is driven, as shown in FIG. 3, the DMIS [I / F] program 36 first reads the first DMIS command from the DMIS command file recorded on the FD sequentially (step 1).
00) Then, the read DMIS commands are sequentially analyzed (step 110). And DMIS [I /
F] The program 36 converts the analyzed DMIS command into a manufacturer-specific CNC procedure (step 1).
20). That is, the DMIS [I / F] program 36
The DMIS commands are sequentially converted into commands (languages) for the CMM 10 (step 130). And
The DMIS [I / F] program 36 sequentially outputs the converted commands (data) to the CMM measurement program 38 (step 140).

When the data is output, the CMM measurement program 38 first executes a measurement by the CMM 10 based on the data (step 15).
0). Next, the CMM measurement program 38 outputs the manufacturer's original measurement result data obtained by the CMM 10 (step 160), and outputs the measurement result data to the DMI.
S [I / F] Output to the program 36.

When the measurement result data is output, the DMIS [I / F] program 36 sequentially converts the measurement result data into a DMIS command output format (step 180) and sequentially writes the data into a DMIS output file (step 180). Step 190). And DMIS [I / F]
The program 36 and the CMM measurement program 38 are DM

When the DMIS command ends, the measurement by the coordinate measuring machine 10 is stopped.

When confirming the measurement result data, the FD storing the DMIS output file 44 is set in the CAD / CAM system 40 as shown in FIG. Thereby, the measurement result data can be confirmed by the DMIS command on the CAD / CAM system. As described above, according to the measuring device control device 30 of the present embodiment, the conversion between the DMIS command of the DMIS command file 42 and the command for the CMM 10 is performed by the same program of the control device 30. So you can
Conversion between commands can be performed without any hassle. That is, in the present embodiment, the measurement program and the translation program can be executed in real time. Therefore, in the present embodiment, the DMIS command file 42
By simply setting the FD in which the FD is recorded in the control device 30, the CMM 10 can be CNC-controlled by the manufacturer's own command, and the result measurement data is also recorded by the DMIS command. Operation of 10 becomes easy.

In the present embodiment, the work is measured while sequentially converting the DMIS command read from the DMIS command file 42 into a command for the coordinate measuring machine 10, so that a common command is previously stored as in the prior art. This eliminates the need for batch conversion to commands for measuring instruments. Further, in the present embodiment, the result of the measurement program can be fed back to the translation program, and it is possible to translate advanced functions of a common language that could not be realized by conventional one-way traffic.

In the present embodiment, the DMIS command has been described as an example of the common command, but another common command may be used.
