parts per month for air suspensions for vans. At the moment, we are finalizing a hinge for the semiconductor industry. This component will be first created in a small quantity, and then, if results are good, we will make 300 or 400 items.” A typical day in the life for Doeko’s eight programmers includes working with Siemens Unigraphics computer-aided-design (CAD) software for part design and with ESPRIT computer-aided-manufacturing (CAM) for part programming. In 1998, Doeko’s managers decided that to remain competitive the company had to adopt CAM software. After checking out all the CAM players on the field, the company chose Esprit from DP Technology for its ability to program parts for every industry and every machining discipline. This was essential because Doeko’s talent lies with its adaptability and knowledge in making a number of different types of complex parts. “We are a very flexible company that must be able to quickly change from one application to another, and with Esprit we can,” Hendriks says. “We don’t need to buy several types of software. When you’re on deadline and accurate CNC code is a must, there is no replacement for reliable, high-performance CAM,” Hendriks explains. Esprit is highly customizable for milling, turning, mill-turn, and wire EDM. Multitasking and high-speed machining, as well as piloting B-axis machine tools, are easily manageable with the software and, with top-notch postprocessors, com- patible with various machine tools right out of the box. In order to achieve the best possible result the first time around, it’s also vital that Esprit be compatible with Unigraphics. Esprit’s seamless CAD-to-CAM interface directly imports any native part model from any source, fully intact, with no need for programmers to edit or rebuild geometry. Esprit also directly machines from any combination of geometries, including solids, surfaces, wireframe, or STL files. Installation of the new CAM technology was arranged by the Esprit reseller in the Netherlands, Greenock CAD Service, based in Ede. After their first training, Doeko’s programmers quickly became familiar with the software and, not long after, were able to work completely independently with Esprit. Doeko credits the responsive team at Greenock CAD Service for its rapid success with Esprit. Doeko, which was up and running in 1998 with four seats of Esprit for wire EDM and milling, today has eight licenses with FreeForm and four-five axis milling, with which 75% of its parts are programmed. Vijverberg recalls a part that the company was tasked with programming before it acquired CAM software. The part, which would become part of a lawn mower, required a whole day of programming. “From my experience, we now need only one hour to launch the machining
of this kind of mold thanks to the CAM system and the memory capacities of our machines.” When asked which parts they are able to produce today without
