NC Modules

In this unit, we discuss the kind of machining modules that can be carried out on a CNC milling machine. Depending on the softwares that is being used, the name of these modules varies. As we are using Pro/NC as our demonstration software, we will also identify the name used under Pro/NC. We will discuss 3 modules in detail and introduce to you what is needed to work in these modules. 1. Profile Milling Other softwares may call this contour milling. Under this module, the software need to know how you want to approach/retract from the workpiece. How much you want to leave behind (or overcut, if needed), and how many rounds that you want to loop. 2. Pocket Milling Pro/NC has a powerful module called Volume Milling, and it has also a Pocketing module. We are using the Volume Milling to create Pocket Milling. Regardless of the name, what is required include, approach point, cutting method, cutting direction and how deep you want to cut. We will also discuss about the problems arises from the inclusion of an island. 3. Cycles Pro/NC called this module, Holemaking. As the name suggests, it is mainly in the making of holes, countersink hole, tap hole ream hole, deep hole, etc. What the module requires include the initial height, retract height, depth of the hole, peck drilling parameters etc.
