Abstract

This invention provides an information processing apparatus that performs maintenance of a machine tool based on received measurement data. The information processing apparatus includes an acquirer that acquires maintenance information including measurement data by a measuring instrument attached to a machine tool and identification information of the machine tool, a calculator that calculates an operation accuracy of the machine tool using the acquired maintenance information, and a correction information generator that generates correction information of the machine tool based on a calculation result by the calculator.

First claim

The invention claimed is:

1. An information processing apparatus for remotely correcting movement of a machine tool on the basis of measurement data measured by a measuring instrument attached to the machine tool during a licensing period of the measuring instrument, comprising:
at least one processor; and
a memory storing instructions that, when executed by the at least one processor, cause the information processing apparatus to:
acquire maintenance information including the measurement data and identification information of the machine tool from the machine tool or the measuring instrument;
analyze the acquired maintenance information to calculate the licensing period of the measuring instrument and to determine if the measurement data is measured within the licensing period;
calculate an operation accuracy of the machine tool using the acquired maintenance information to obtain a calculation result;
generate correction information of the machine tool based on the calculation result and transmit the correction information to the machine tool; and
analyze the maintenance information and determine whether the measurement data is data measured during the licensing period of the measuring instrument,
wherein if it is determined that the measurement data is not the data measured during the licensing period, the correction information is not generated, and
wherein if the information processing apparatus determines that the measurement data is the data measured during the licensing period, the correction information is transmitted to the machine tool to correct the operation of the machine tool.

2. The information processing apparatus according to claim 1 , wherein said memory stores instructions that, when executed by the at least one processor, also cause the information processing apparatus to:
further acquire operation information of the machine tool, and
generate the correction information of the machine tool based on the operation information as well.

3. The information processing apparatus according to claim 2 , wherein
the operation information is a temperature inside the machine tool, and
generating does not use, for generation of the correction information of the machine tool, the measurement data measured in a state in which the temperature inside the machine tool exceeds a predetermined temperature.

4. The information processing apparatus according to claim 2 , wherein
the operation information is an operation history of the machine tool, and
generating does not use, for generation of the correction information of the machine tool, the measurement data measured in a state in which a predetermined time has not elapsed yet from an operation of the machine tool.

5. The information processing apparatus of claim 1 , wherein the operation accuracy is a positioning accuracy.

6. An information processing apparatus for remotely correcting movement of a machine tool on the basis of measurement data measured by a measuring instrument attached to the machine tool during a licensing period of the measuring instrument, comprising:
at least one processor; and
a memory storing instructions that, when executed by the at least one processor, cause the information processing apparatus to:
acquire maintenance information including the measurement data and identification information of the machine tool from the machine tool or the measuring instrument;
analyze the acquired maintenance information to calculate the licensing period of the measuring instrument and to determine if the measurement data is measured within the licensing period;
calculate an operation accuracy of the machine tool using the acquired maintenance information to obtain a calculation result;
generate correction information of the machine tool based on the calculation result and transmit the correction information to the machine tool; and
analyze the maintenance information and derive a calibration period of the machine tool,
wherein if it is not the calibration period, the correction information is not generated, and
wherein if it is the calibration period, the correction information is transmitted to the machine tool to correct the operation of the machine tool.

7. The information processing apparatus of claim 6 , wherein the operation accuracy is a positioning accuracy.

8. An information processing method for remotely correcting movement of a machine tool on the basis of measurement data measured by a measuring instrument attached to the machine tool during a licensing period of the measuring instrument, comprising:
acquiring maintenance information including the measurement data and identification information of the machine tool from the machine tool or the measuring instrument;
analyzing the acquired maintenance information to calculate the licensing period of the measuring instrument and to determine if the measurement data is measured within the licensing period;
calculating an operation accuracy of the machine tool using the acquired maintenance information;
generating correction information of the machine tool based on a calculation result in the calculating;
transmitting the correction information to the machine tool;
analyzing the maintenance information and determining whether the measurement data is data measured during the licensing period of the measuring instrument,
wherein if it is determined that the measurement data is not the data measured during the licensing period, the correction information is not generated, and
wherein if it is determined that the measurement data is the data measured during the licensing period, the correction information is transmitted to the machine tool to correct the operation of the machine tool.

9. The information processing method of claim 8 , wherein the operation accuracy is a positioning accuracy.

10. An information processing method for remotely correcting movement of a machine tool on the basis of measurement data measured by a measuring instrument attached to the machine tool during a licensing period of the measuring instrument, comprising:
acquiring maintenance information including the measurement data and identification information of the machine tool from the machine tool or the measuring instrument;
analyzing the acquired maintenance information to calculate the licensing period of the measuring instrument and to determine if the measurement data is measured within the licensing period;
calculating an operation accuracy of the machine tool using the acquired maintenance information;
generating correction information of the machine tool based on a calculation result by said calculator;
transmitting the correction information to the machine tool; and
analyzing the maintenance information and deriving a calibration period of the machine tool,
wherein if it is not the calibration period, the correction information is not generated, and
wherein if it is the calibration period, the correction information is transmitted to the machine tool to correct the operation of the machine tool.

11. The information processing method of claim 10 , wherein the operation accuracy is a positioning accuracy.
