Automation: Adaptive Machining for High Precision Fabrication

Expand your professional knowledge, network with colleagues, and gain insights into new technologies and ideas by registering today for the IMTS 2016 Conferences.

It is any manufacturer’s goal to create an in-spec, high quality product every time. However, even with all the advances we’ve seen in machining and manufacturing over the years, errors and deviations are still a very real problem.

Today, parts are built on computer aided design (CAD) systems before they’re ever built in real materials. Once the model is created, engineers will use computer-aided manufacturing (CAM) software to generate a cutting path that will generate the finished part from the initial work piece. The CNC machine is programmed to create parts based on the computer-generated ideal templates, and cannot take into account deviations or other geometrical abnormalities that the actual part materials may contain.

TechSolve has developed an adaptive machining system that enables generation of a dimensionally correct part via compensations for the as-is geometrical imperfections of a work piece. This system was demonstrated successfully on a composite component representative of a structural part of an airplane.

Manufacturers can use this smart technology to reduce scrap and improve quality and consistency for each machined part. This technology allows manufacturers to feel more confident when machining near net shape, small stock allowance components, whether such components are made of metals or composite materials.

About the speaker

Dr. Radu Pavel joined TechSolve in 2004, bringing with him research and development skills in manufacturing processes, particularly machining and grinding. His expertise is focused on process design and optimization as well as process monitoring and control. Radu has successfully worked and completed numerous R&D projects supporting the manufacturing industry throughout the United States. Investigating, designing, and evaluating advanced technologies, he works to increase knowledge of advanced machining systems, and aids in the transition of that knowledge to industry through hands-on implementation and training.
