Data Models For Product Modification using Reverse Engineering

 

Reverse engineering is the process of giving out a system, device or object to view the different parts of this object and try to understand how each of them work with the others to create one functional unit. This process is necessary because people have been able to understand how technology operates and you it can be applied and maximized. Improvements can be done through the innovation of applied technology, making innovations much better.

 

Traditionally, reverse engineering services used analog and GPS scanning technology to gather spatial data of operating systems and objects. Today laser scanners have replaced these traditional methods.

 

3D Modeling for Plants offers many benefits over the traditional scanning methods especially when it comes to time and cost of scanning. Reverse engineering services use laser scanners for a variety of applications but in each case, the scanning results are used to produce models that allow the company to fabricate objects with relative ease. The models include the hybrid surface models, the parametric, and shrinkwrap surface models.

 

The Parametric Models

This model converts ideal or realistic data from scanned data and can choose to ignore or incorporate manufacturing defects. This means that the parameters used in the parametric model are expressed in finite-dimensional parameter spaces distinguishing them from nonparametric models, semiparametric models, and semi-nonparametric models. Parametric models are commonly used when 2D drawings are needed, when the surface of a product must be smooth,  when parts will be built on or around a scanned part or when scanning data will be conceptually modified.

Hybrid Surface Model

Similar to the parametric models, hybrid surface models can convert realistic data from scanned data, and can ignore or include the manufacturing defects. Hybrid surface model is used when the modification of the object requires refining or must be a class-A surfaced. Hybrid surface models, just as their name suggests are used when only the surface of an object requires modification, and are therefore suitable when superficial modifications are made part of the object. This model is also ideal when 2D drawings are required when building on or around an object that is scanned or when surface finish of an object must be smooth.

Shrinkwrap Surface Model

The shrinkwrap surface models are used to take objects in their original state including the manufacturing defects; hence they are ideal for designing parts to accommodate as-built models. There are three type of shrink wrap models--surface subset models, which are used to create a collection of outside surfaces and datum figures; solid faceted models, which are used to provide an approximate representation of the original item; and the subset surface models used to approximate the visual representation of the initial object.
