Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of preshaped material that is secured to the fixture, which itself is attached
Center the rotary table on the mill, indicate the 916 hole to center, and figure the tool offset need to generate the hole. Raise the knee .10034 and take the first 360 cut. Continue raising the knee on each cut while bringing the cutter closer to centerline.
Large diameter holes when machine power is limited Smaller series production. A rule of thumb for diameters larger than 25 mm milling is costefficient up to a series of approx. 500 holes When a range of hole sizes are to be machined Limited tool magazine space to store many drill sizes Production of blind holes, when a flat bottom is required
