Cad for cnc11/13/2023 ![]() ![]() It turns out our planet is full of bubbles filled with highly focused people with specialized intelligence and abilities. We grow up and live out our lives seeing the world from inside our bubble, thinking what we know and experience is at the center. Those old days ended with the invention of computers in Germany in 1936 or 1938 and CNC machines in Traverse City, Michigan in 1940. Once programmed by CAD, the CNC Router can produce in minutes what it took arcticians months to produce in the old days. He can produce intricately carved wooden picture frames like the ones you see in museums. “Whatever I can draw, I can make.” My brother’s CNC Router cuts bevels and shapes the inner panels of fancy kitchen cabinets. They are farmed out to small machining companies around Michigan.”Īccording to Mick, CNC machines are custom-made for different operations. “For instance,” Mick said, “the automotive companies make the major parts for a car in the house, but the door handles, taillights or the switches that run your power windows change from year to year. The automated nature of the CNC machining process enables the accurate production of precision parts that are competitively priced. Then he pushes a button on his CNC machine and the CAM, computer-aided machining, takes off and makes the part. That program will develop the digital language that the CNC machine recognizes. My brother, Mick, claims he can photocopy all sides of an object with his handheld laser, and feed the information into his CAD, computer-aided design. We can focus our energy on producing products with our CNC machines in this space.” It’s easy to ship from all the loading docks inside this building. We had to drive our loaded forklift down that road to the trucks. Shipping companies avoided our dirt driveway, especially after a rain. “We came from a shop less than half the size that was down a muddy dirt road. “We like all the space we have at our Falahee Road facility,” Levy said. ![]() Robert Levy told me they use CNC mills and lathes, wire EDM, and, of course a CMM for the final part check before shipment. Our new tenant, Levy Machining, uses a wide variety of CNC equipment to make parts for industries across the country. The stock materials can be metals, plastics, wood, glass, foam, or composites.ĬNC machines can also do additive manufacturing, by assembling layers of material to produce a form. This method employs computerized controls and machine tools to remove layers of material from a stock piece and produce a custom-designed part. One process the CNC machine utilizes is a subtractive manufacturing process. Turns out CNC means computer numerical control, CAD means computer-aided design, and CAM means computer-aided machining. He patiently explained the facts of CNC machining to his little sister. My brother has been taking classes at machining centers in Saginaw and Bay City for over ten years. Mick Hartman lives in Standish and has a “man cave” with several CNC machines. I knew they produced widgets for the car companies, but had no idea what the acronyms CNC, CAD or CAM meant. When I was growing up, that was implicit, as was the knowledge that the three major auto companies dominated business in my home state.īut when our new tenant at our Michigan Center building, Levy Machining, rolled in rows of bulky CNC machines, I realized I knew little about what my uncles and neighbors did at the factories in Flint and Bay City. Michigan has been known for its skilled workforce for years men and women with highly focused mechanical intelligence and abilities. ![]()
