Abstract

Development of Laboratory Modules for Use in Measurement and Instrumentation, and Applied Quality Control CoursesEquipping engineering students with the skills and knowledge required to be successful globalengineers in the 21st century is one of the primary objectives of undergraduate educators.Ideally, a properly trained workforce of engineers and technicians should have expert skills inquality control, measurements and instrumentation to maintain higher productivity, and toimprove safety standards in the industry. An expert can detect and/or predict deteriorating cuttingconditions through the use of his/her senses so that appropriate corrective actions can be takenbefore part quality is lost. However, this level of expertise requires many years of experience.Furthermore, machine tools should be brought to a thermally stable state by running at idle modefor several hours so that positional errors can be minimized. This requirement increases machinedown time and production costs. Machine tools have inherent geometric errors caused bymechanical imperfections in their structure, and misalignment of machine tool elements.Geometric errors are also affected by the thermal state of the machine tool structure. Henceprocess and structural factors affecting part accuracy in machining processes are quitecomplicated. CNC machine tools only minimizes a small portion of these errors since CNC oftendoes not utilize sensor data to compensate for geometric-thermal errors and errors generated bythe cutting process. Therefore, we must provide our students, through our curriculum, with anadequate level of expertise through new programs, courses and support laboratories.This paper is focused on description of new laboratory modules, teaching materials, practicalexperiments and projects developed as an integrated educational environment similar to onesused in the present day industry. The projects and practical activities are developed andimplemented around Renishaw Magnetic Double Ballbar (DBB), HAAS OM1A 3-Axis CNCVertical Machining Center and Coordinate Measuring Machine (CMM). Course materials andlaboratory manuals are also developed, upgraded and restructured during this project. Theeducational material is implemented as course improvements in undergraduate and graduatecourses such as Measurement and Instrumentation, Applied Quality Control, EngineeringQuality Methods (graduate) and Sensors and Measurements (graduate).The experimental activities are focused on several aspects applicable in manufacturing industryconcerning measurement, instrumentation and quality control. One area where we concentratedour efforts is the calibration technology of a CNC using machined parts and a CMM. Thisapproach yields valuable information on non-repeatable errors due to cutting forces, heatgenerated by cutting, tool setup, wear, and deflection. CMM is used also as a post processconfirmation of the machined test components and other discrete parts machined in the HAAS-OM1 Vertical Machining Center. Then the deviation between the real part and the theoreticalpart is measured. Another area of focus is related to characterization of the factors and errorcomponents that contribute to machine tool errors using a DBB.
