“In addition to introducing students to manufacturing, the
program teaches them how to work, how to live and how to contribute. Subsequently, they articulate better and are more likely to see project through to the end.” Industry Certifi cations available to high school students
through PLTW include Verisurf Software, Solidworks Soft- ware, AutoDesk Inventor Software and NIMS (National Insti- tute of Metalworking Skills) Certifi cation. PLTW serves as a primer for students considering manu- facturing as a career path. It also provides an introduction to college-level certifi cate programs and college credits toward degree programs. Years ago, industrial arts programs at the high school level
were nearly eliminated. Today, many of these programs are being reintroduced, with closer ties to real-world applications and industry relevance. For many, the path to becoming a manufacturing technician now begins in high school. With the right exposure, a student can gain a real interest in manufac- turing and gain a greater appreciation for subjects like math and science. Applying these subjects through the practical applications of machining, robotics, 3D design and engineer- ing makes the light burn bright for many students: They are now purpose driven. The concept of combining practical ap- plication along with theoretical teachings is powerful.
Associates Degree and Certifi cate Programs Cerritos College offers classes with standardized curriculum on many aspects of manufacturing, including Machinist, Numeri- cal Control Machine Operator, Numerical Control Tool Program- mer, Coordinate Metrology, Tool and Die Maker, CAD Designer, CAM Programmer, Plastics and Composites Technology, Fabri- cating and Woodworking. Many of the courses offer certifi cate programs, as well as credit toward an Associate degree.
Bachelor of Science Cerritos College partners with Northwood University to
offer students who want to continue their education and receive a B.S. in Applied Management with a technical em- phasis in Machine Tool Technology. Northwood offers cost- effective, accelerated degree completion, and the eligibility criteria is in line with the Associate degree in Machine Tool Technology offered by Cerritos College. “The whole idea behind the programs at Cerritos College is to enlighten students, as early as possible, about manufac- turing technology as a vocation and viable career path,” Real said. “Once the passion has been ignited we want to provide
students the most comprehensive and practical education we can—learning by doing.”
Coordinate Metrology and the Digital Thread Today’s design, manufacturing and quality engineers are becoming increasingly accountable to maintain a digital work- fl ow, end-to-end. To this end, modern manufacturing is rapidly adopting model-based defi nition (MBD). When employing an MBD strategy, the CAD model becomes more than the nominal to which all parts are measured and inspected against. MBD keeps the all-important digital thread intact—from design to manufacturing to inspection and quality reporting. Everything that defi nes the part exists in a single digital archive, including how to manufacture and inspect the part. Of course, a com- prehensive deployment of MBD in manufacturing can go far beyond this to complete Product Lifecycle Management (PLM), but it is important for students to understand the concept.
Reverse Engineering Using coordinate metrology, reverse engineering is taught for use in determining best fi t, producing legacy parts with missing CAD data, or manufacturing complex surface pro- fi les—in each case adding value to the all-important digital thread. These are just a few examples of providing students with relevant and modern concepts that will increase their value as technicians in the workplace.
Quality Inspection Quality inspection and reporting used to be a disparate
process isolated in a quality lab. Today, it is much more inte- grated with the production fl oor through in-process inspec- tion. Students are taught the importance of cross-platform compatibility, starting with deployment of an enterprise inspection software and extends to all coordinate measur- ing machines (CMMs) and accessories. Today’s inspection software solutions are capable of serving the entire manu- facturing enterprise. In order to maintain the digital thread, software must be rooted in CAD and have the ability to im- port from, manipulate, annotate, model, inspect against, and export to virtually any CAD fi le format. At the end of the day, it is the job of inspection software to align and compare the nominal CAD model with measured points collected from the fi nished part, whether that includes a relatively small number of manually triggered contact points, or noncontact scanned point cloud data containing millions of points.
