Form Fit Or Function. The f3 framework increases design change flexibility by allowing changes to the part with minimal documentation and design cost as long as the fit, form. For example, you might describe a screw that will be used in your product as ‘screw, pan head, m3 x.
Form, Fit, and Function
Web “form, fit, and function” are most commonly discussed in relation to the design of an object, or when considering if a process is value added or not. Web form, fit and function rules specify how much new revisions of a part can deviate from the original before new part numbers are created. Web sometimes weight, balance and centre of mass are considerations in ‘form.’. It includes things like shape, weight, color, material, etc. This is key in ensuring components can be substituted without issue. Each defines a specific aspect of the part to help engineers match parts to needs. Fit is the ability of an item to physically interface with all other components. Web all of my experience says to revise a drawing if there is a change to the form, fit, or function of a given part. If it can be changed by increasing the revision of the component or assembly, or if a new component or assembly has to be created and given a new part number when it is changed. Ansi states if a part is not backward compatible then is gets a new part number not a new revision.
Here is the challenge, it is hard. Web form, fit and function rules specify how much new revisions of a part can deviate from the original before new part numbers are created. Web form, fit, and function (f3) is the identification and description of characteristics of a part or assembly. It includes things like shape, weight, color, material, etc. If it can be changed by increasing the revision of the component or assembly, or if a new component or assembly has to be created and given a new part number when it is changed. This also includes tolerances modifications. Categories engineering & design hints, tips & how tos The f3 framework increases design change flexibility by allowing changes to the part with minimal documentation and design cost as long as the fit, form. Here is the challenge, it is hard. This is key in ensuring components can be substituted without issue. Web so, the form, fit, function (fff) factor describes the criteria or characteristic of the component or an entire assembly from the identification standpoint.
