Software Software Pages 5 to 12 Many times CNC manufacturing businesses seek out CNC programming software only to find that they end up paying for CAM technology that they really don't need, along with maintenance that they will never use. A simple solution to this is the development of modular CAD/CAM software, which allows different software functionalities to be available independently of one another. This means that shops that need 2.5-axis machining capabilities can acquire it without having to pay for software functionality that they will not use. Giving CNC businesses the ability to add on to a CAD/CAM product as needed for upgrade costs in functionality is a better way to help shops grow as they learn CAM technology and employ it into their operation. A shop that has a CNC router may start off with a complete 2-axis CAD/CAM system that allows them to create 2.5 axis toolpath and G-code programs for a router. The same company may then acquire a 3-axis CNC machine down the road, and would be able to add on to the software and upgrade to the next level, at very low cost, in order to take advantage of machining technology for 3-axis, and so on. For small shops, this makes more sense than the alternative, which is to have to pay more money for more technology, which some shops simply wouldn't use until the right job came along. Shops can save money by upgrading CAD/CAM software to add higher level toolpaths and programming functionality, such as a multi-axis package, which can include seven surfacebased toolpaths that increases the user's ability to control where and how material is removed. Since it doesn't cost as much for an upgrade as it would to buy an entirely new package, this is recommended as the better route for shops to take. Starting with a simple 2-axis product and gaining the skill set to be utilized with the higher end features that a multiaxis package offers when warranted. Multiaxis is just that, not only does it offer more toolpath options, it also supports 4- and 5-axis output. As your parts get more complicated to machine, it usually means you are adding a 4th or 5th axis to eliminate setup time or just to have the ability to cut the parts according to the design. Suppliers that offer 4- and 5-axis upgrades are able to support table-table, head-table and head-head machine configurations, giving CNC businesses a more affordable path to acquire this type of technology. 12 MoldMaking Technology July 2013 Images by BobCAD-CAM. The Benefits of Modular CAD/CAM Screen shots of mold design inside CAD software. Other modules offer CNC machining capabilities such as lathe, part nesting and sheet optimizing, as well as artistic CAD/CAM, which allows the user to take a picture and turn it into a relief model or profile geometry that can then be machined. The point is that these modules can be purchased separately, so businesses can introduce these functions into their shops as the need arises. Shops can save money and add technology as they grow.
