There are two reasons why many companies are reluctant to use ultrasonic profilers. For one thing, the profiler doesn’t always appear to be cutting on the first try. The second reason is the high cost of such machines. The truth is that in the hands of an experienced veteran, an ultrasonic profiler can easily cut

Gisbert Ledvon If you build a multi-cavity with a large surface area in each cavity, consistency in surface finish and surface integrity is a must. Otherwise, you will get surface finish differences on the molded parts and may have difficulties ejecting the parts from the cavity. However, large surfaces that are EDM’ed via diesinking often

It’s the age-old story. You win a mold contract, you work on the designs, the measurements and the tolerances, and then you think you have it all together and you’re ready to roll. But are you? More times than not, customers come rushing over or calling on the phone with an urgent polishing and plating

You must produce a rib style cavity using an electrode that is ten thousandths at the tip plus one degree draft per side. Then burn to a depth of minus 1.1000 inch into a piece of 420 stainless steel – no through or side flushing is used on this cut. The project requires a surface

Applications/programming engineers get to hear all kinds of machining problems on a daily basis. The one that seems to stand out as the most baffling really is not that difficult to solve once you analyze exactly what is happening. Drilling small diameter holes presents numerous problems. Small diameter holes refers to holes of 0.125″ diameter

Quality policy – Develop a statement of your company’s commitment to quality. Use this framework for subsequent planning and action. Quality aspects – Identify quality attributes of your company’s products, activities and customer services. Determine the attributes that have or could have significant impacts on the quality. Keep this information up-to-date. Legal and other requirements

If your shop is considering ISO 9001, there are a number of things you can do to simplify the effort: Define your company’s goal. Obtain top management support. Experience shows that establishing a quality management system that conforms to ISO 9001 is virtually impossible without solid support from top management. Management must understand the costs

Digital prototyping gives designers and engineers the ability to virtually explore a complete product before it is built;so they can design, visualize and simulate products from the conceptual design phase through the manufacturing process. By using a digital prototype, users access real-world performance of a design with less reliance on costly physical prototypes. While simulation
