Laser Aided Manufacturing Process (LAMP)


"The Laser Aided Manufacturing Process (LAMP) is a multi-axis hybrid manufacturing process comprised of both an additive process, laser deposition, and a subtractive process, CNC machining. Work-piece alignment is a key issue for hybrid laser aided part repair. Proper alignment can greatly improve the accuracy of the repair process. Paper I introduces a method for aligning a physical work piece and a CAD model using a Renishaw touch probe and software tools. Also discussed is a model for computing 5-axis CNC positions based on a desired work piece orientation.

Determination of transformation matrix is one of the most important tasks to bridge the gap between process planning (software) and real deposition/machining process. The first part of the Paper II discusses an algorithm for computing the position of point/points in three-dimensional space, using homogeneous transformation matrices. The second part of the paper discusses about how the algorithm was used in practice to build 3-D parts and part-repair using hybrid manufacturing process"--Abstract, page iv.
