Form Fit Function Data

A related topic is regression analysis which.

Form fit function data. Typically if the change to a part is significant enough that the new part cannot be used in place of the previous version for example if the size of a screw changes then a new part number must be created. Form fit and function data means data relating to items components or processes that are sufficient to enable physical and functional interchangeability and data identifying source size configuration mating and attachment characteristics functional characteristics and performance requirements. The definitions above describe what three fff represent on their own. Finally we can check the fit of the equation to the data by plotting both on the same chart.

Smaller data values are going to result in a smaller sum of squared residuals than larger values. 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 and function of the product are maintained. Form fit and function f3 is the identification and description of characteristics of a part or assembly. Form fit and function models.

The header data of every fff class contains an additional indicator restricted interchangeability allowed. You defined a leading product for each fff subset. In the master data for product and location interchangeability you created form fit function classes and you created location specific form fit function subsets fff subsets for each form fit function class. Form fit and function data form fit and function data means data relating to items components or processes that are sufficient to enable physical and functional interchangeability and data identifying source size configuration mating and attachment characteristics functional characteristics and performance requirements.

Each defines a specific aspect of the part to help engineers match parts to needs. Curve fitting is the process of constructing a curve or mathematical function that has the best fit to a series of data points possibly subject to constraints. Form fit and function data means technical data that describes the required overall physical functional and performance characteristics along with the qualification requirements if applicable of an item component or process to the extent necessary to permit identification of physically and functionally interchangeable items for computer software it means data identifying source. But the object of our discussion is the form fit and function model which includes in its definition a very important subject for manufacturers.

Form fit function rules specify how far new versions of a part can deviate from the original before new part numbers are created.
