Abstract
Abstract The invention relates to a method and to apparatus for manufacturing a plurality of mutually similar objects or assemblies, where each assembly comprises at least two mutually coacting elements of mutually different types or configurations and each having a respective critical dimension which is determinative of the function and/or the quality of the coaction between the elements. According to the invention, a manufacturing device (1) for manufacturing a first type of element of the mutually coacting elements is provided with a measuring device (3) for measuring the critical dimension of each individual first type of element. A manufacturing device (2) for manufacturing a second type of element of the mutually coacting elements is provided with a measuring device (4) for measuring the critical dimension of each individual second type of element. The measured values for each individual element of both types are stored in a data storage device (5) together with information concerning the identify of the element. An element assembling device (8) is connected to the data storage device (5), which on the basis of information stored therein controls the assembly device (8) in a manner to select and assemble those elements which will fulfil optimally a predetermined criterium with respect to the function and/or the quality of the coaction between the elements.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A method for manufacturing a plurality of mutually similar objects or assemblies, in which each assembly comprises at least two mutually coacting elements of mutually different types, each having a critical dimension which determines the function and/or quality of the coaction between said elements, characterized by measuring the critical dimension of each individual element in conjunction with the manufacture of said elements; storing the measured value of each individual element together with data disclosing the identify of said elements; selecting for the production of each assembly an element of each separate type on the basis of the measured and stored values of the critical dimensions, said elements being selected to fulfil optimally a predetermined criterion concerning the function and/or quality of the coaction between the elements; and thereafter assembling the elements.
Claim 2
Independent Claim
131 words
A method for manufacturing a plurality of mutually similar objects or assemblies, in which each assembly comprises at least two mutually coacting elements of mutually different types, each having a critical dimension which determines the function and/or quality of the coaction between said elements, characterized by measuring the critical dimension of each individual element in conjunction with the manufacture of said elements; storing the measured value of each individual element together with data disclosing the identify of said elements; selecting for the production of each assembly an element of each separate type on the basis of the measured and stored values of the critical dimensions, said elements being selected to fulfil optimally a predetermined criterion concerning the function and/or quality of the coaction between the elements; and thereafter assembling the elements.
Claim 3
Dependent Claim
87 words
A method according to Claim 1, characterized by first producing all elements of a first element type in the manufacture of said elements, using the measured and stored distribution of the critical dimension of the elements of the first type to control a device used in the manufacture of the remaining elements; and by manufacturing said remaining elements with a critical dimension distribution which is adapted to the critical dimension distribution of the elements of said first type, therewith enabling the predetermined criterion to be optimally fulfilled.
Claim 4
Dependent Claim
50 words
A method according to Claim 1 or 2, characterized by storing the measured values and data concerning the iden tity of the elements in a computer, selecting the elements with the aid of said computer, and controlling at least one device for assembling said elements by means of said computer.
Claim 5
Dependent Claim
226 words
Apparatus for manufacturing a plurality of mutually similar objects or assemblies, in which each assembly comprises at least two mutually coacting elements of mutually different types, each having a critical dimension which is determinative of the function and/or quality of the coaction between said elements, characterized in that a device (1) for manufacturing a first type of the mutually coacting elements is provided with a measuring device (3) for measuring the critical dimension of each individual element, the measured value for each individual element being stored in a data storage device (5) together with information relating to the identity of said elements; in that a second manufacturing device (2) for manufacturing a second type of said mutually coacting elements is provided with a measuring device (4) for measuring the critical dimensions of each individual element, the measured value of each individual element being stored in said data storage device (5) together with information concerning the identity of said elements; and in that an assembling device (8) is connected with the data storage device (5); and in that the data storage device is constructed to control said assembling device (8) on the basis of information stored therein, in a manner to select and assemble those elements which will fulfil optimally a predetermined criterion with respect to the function and/or the quality of the coaction between said elements.
Claim 6
Dependent Claim
226 words
Apparatus for manufacturing a plurality of mutually similar objects or assemblies, in which each assembly comprises at least two mutually coacting elements of mutually different types, each having a critical dimension which is determinative of the function and/or quality of the coaction between said elements, characterized in that a device (1) for manufacturing a first type of the mutually coacting elements is provided with a measuring device (3) for measuring the critical dimension of each individual element, the measured value for each individual element being stored in a data storage device (5) together with information relating to the identity of said elements; in that a second manufacturing device (2) for manufacturing a second type of said mutually coacting elements is provided with a measuring device (4) for measuring the critical dimensions of each individual element, the measured value of each individual element being stored in said data storage device (5) together with information concerning the identity of said elements; and in that an assembling device (8) is connected with the data storage device (5); and in that the data storage device is constructed to control said assembling device (8) on the basis of information stored therein, in a manner to select and assemble those elements which will fulfil optimally a predetermined criterion with respect to the function and/or the quality of the coaction between said elements.
Claim 7
Dependent Claim
31 words
Apparatus according to Claim 4, characterized in that the data storage device is a computer (5); and in that the assembling device includes an industrial robot (8) controlled by said computer.
