As a tool is used, it wears down and its performance grad- ually deteriorates. When you're looking for the best possible finish, always use a new router bit. Ask the experts. Choosing the correct cutter for the job can be a confusing and time-consuming process because it can in- volve testing a multitude of tools on a var- iety of materials. A more effective method for selecting the right cutter is to partner with an experienced CNC router supplier. An experienced supplier is one who has invested the time to test available cutting tools to determine the best tool for cut- ting specific materials. These suppliers have many years of experience cutting all types of materials and recognize that the best tool for each type can come from different manufacturers. They also have qualified application specialists to provide guidance regarding the choice of cutting tool and related machine settings. Tap into this knowledge and expertise for questions and assistance with choosing and using the correct cutter to achieve the best cut quality. CASE STUDY: ROEHM AMERICA LLC Roehm America LLC is a manufactur- er of acrylic (polymethyl methacrylate or PMMA) sheets, branded under the Acrylite trademark. These acrylic sheet products can be found in a variety of industries, such as architecture, furniture, trade show, and sign construction, to mention just a few. In 2015, they were searching for a ma- chine that could produce a high-quality edge finish on acrylic directly from the router. They purchased an AXYZ Pacer machine. "We use this router for demonstrations during our customer training and testing of all new Acrylite sheet products," ex- plains Brian Fraser, innovation manager at Roehm. Today, Roehm uses the CNC router to fabricate acrylic parts, new acryl- ic prototypes, testing machinability of new acrylic products, and customer and internal routing training. Many acrylic pieces are cut with an edge finish that eliminates the need for addition- al edge finishing operations. Not only does this save time, but it's a huge reduction in labor costs.

When working with aluminum versus acrylic, ma- chinists should evaluate the best cutter for the job (seen here is aluminum). (Image courtesy ShopBot Tools)
