Form Fit Or Function. 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. Ansi states if a part is not backward compatible then is gets a new part number not a new revision.
Form, Fit, and Function (FFF) Definition Arena
Web sometimes weight, balance and centre of mass are considerations in ‘form.’. Web so, the form, fit, function (fff) factor describes the criteria or characteristic of the component or an entire assembly from the identification standpoint. 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. Fit is short for “fits intended application”. This is key in ensuring components can be substituted without issue. 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. Fit is the ability of an item to physically interface with all other components. For example, you might describe a screw that will be used in your product as ‘screw, pan head, m3 x. 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. Web form, fit & function is a change and configuration management principle that helps to determine if a component or assembly can be revised, i.e.
Web form, fit, and function data technical data (td) pertaining to items, components, or processes for the purpose of identifying source, size, configuration, mating and attachment characteristics, functional characteristics, and performance requirements. 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. Categories engineering & design hints, tips & how tos Web sometimes weight, balance and centre of mass are considerations in ‘form.’.
