A design recovery framework for mechanical components

A design and inspection based methodology for form-function reverse engineering of mechanical components

“…Presently, there is a wide variety of commercial data acquisition tools and mathematical algorithms [1][2][3][4][5][6][7][8][9] to transform point cloud data into sets of curves and surfaces. This process in itself is not comprehensive reverse engineering when the target applications are mechanical components [10] but is a core element of the design recovery process. There are several approaches which be taken to acquire digitized data using contact and noncontact systems.…”

“…There are unique reverse geometry modeling challenges associated with mechanical components, as recognized by several researchers [10,[21][22][23][24][25][26][27][28]. Complex mechanical components consist of features composed primitive and complex free form shapes, designed to satisfy a set of functional requirements [29].…”

“…The result is then compared to a model constructed utilizing a formalized design recovery approach. The full description of the design recovery process is described in [10].…”

“…Using a systematic design recovery approach [10,24,31], component functions are identified, the interface conditions assessed, and purposeful curve geometry is created using the collected point cloud data as a template, which results in an idealized CAD model being generated using standard CAD modeling tools (Fig. 4).…”

“…The challenge is to systematically assess the features and determine the type of data, amount of data, and the data [10] collection tools required for functional design reconstruction. This challenge complements both design and inspection planning strategies for a new component.…”
