Abstract

A tolerance display system allows workers to easily obtain accurate size information at actual worksites. The tolerance display system includes a tolerance display device which has a storage device storing standards data/files related to general tolerance, an information input device for inputting information, an operation unit for reading out standards data related to a general tolerance from the storage device based on data input by the information input device and calculating limits of size, and an output device for displaying the standards data, the limits of size and other information. The information input device includes an industry type menu input portion for selecting and inputting a product name of a desired industry type, a specified condition input portion for inputting specified conditions such as a special item, a tolerance class, a basic dimension, and a numerical value/arithmetic operator input portion for inputting a numerical value/arithmetic operator.

Claims

1. A tolerance display system, comprising:

a storage device storing standards data/files related to a general tolerance;

an information input device arranged to input prescribed information;

an operation unit arranged to read out standards data related to said general tolerance from said storage device based on data input by said information input device, and calculating limits of size;

an output device arranged to display said input data, said standards data, and said limits of size; and

a controller arranged to manage and control said storage device, said input device, said operation unit and said output device;

said information input device including;

an industry type menu input portion for selecting and inputting an industry type represented by the type of a desired product;

a specified condition input portion for inputting a specified condition including at least one of a special item, a tolerance class, or a basic dimension; and

a numerical value/arithmetic operator input portion for inputting a numerical value/an arithmetic operator;

wherein

said industry type menu input portion includes an industry type menu input keyboard for selecting an industry type represented by a name of a desired product, said numerical value/arithmetic operator input portion includes a numerical value/arithmetic operator input keyboard for inputting a numerical value/an arithmetic operator, and said specified condition input portion includes a special item input keyboard for inputting said special item of interest including at least one of the type of a shape, the type of a product, the type of a working method, the type of a material, the type of a size, the type of a geometrical characteristic, a basic dimension division input keyboard for selecting the division of said basic dimension, a tolerance class input keyboard for selecting said tolerance class or a general tolerance input keyboard for inputting a calculated general dimensional tolerance.

2. The tolerance display system according to claim 1, wherein said standards data is automatically retrieved based on said input data, and a calculation processing for limits of size related to the special item of said input industry type menu is carried out.

3. The tolerance display system according to claim 1, wherein said input data, said retrieved standards data, said limits of size obtained by the calculation processing and the unit thereof are displayed by said output device.

4. A tolerance display system, comprising:

storage means storing standards data and files related to a general tolerance;

information input means for inputting prescribed information;

operation means for reading out standards data related to said general tolerance from said storage means based on data input by said information input means, and calculating limits of size;

output means for displaying said input data, said standards data, and said limits of size; and

control means for managing and controlling said storage means, said input means, said operation means and said output means;

said information input means including;

an industry type menu input portion for selecting and inputting an industry type represented by the type of a desired product;

a specified condition input portion for inputting a specified condition such as a special item, a tolerance class, or a basic dimension; and

a numerical value/arithmetic operator input portion for inputting a numerical value/an arithmetic operator;

wherein

said industry type menu input portion includes an industry type menu input keyboard for selecting an industry type represented by a name of a desired product, said numerical value/arithmetic operator input portion includes a numerical value/arithmetic operator input keyboard for inputting a numerical value and an arithmetic operator, and said specified condition input portion includes a special item input keyboard for inputting said special item of interest including at least one of the type of a shape, the type of a product, the type of a working method, the type of a material, the type of a size, the type of a geometrical characteristic, a basic dimension division input keyboard for selecting the division of said basic dimension, a tolerance class input keyboard for selecting said tolerance class armor a general tolerance input keyboard for inputting a calculated general dimensional tolerance.

5. The tolerance display system according to claim 4, wherein said standards data is automatically retrieved based on said input data, and a calculation processing for limits of size related to the special item of said input industry type menu is carried out.

6. The tolerance display system according to claim 4, wherein said input data, said retrieved standards data, said limits of size obtained by the calculation processing and the unit thereof are displayed by said output means.
