An aluminum block of length 50 mm and width 70 mm is being milled using a slab milling cutter with 50 mm diameter. The feed of the table is 15 mm/min. The milling cutter rotates at 60 RPM in clockwise direction and width of cut is equal to the width of the workpiece. Draw a neat sketchof the milling operation describing aboveconditions. The
3. Milling • Milling – A machine operation in which a work part is fed past a rotating cylindrical tool with multiple edges. (milling machine) • Types – Peripheral milling • Slab, slotting, side and straddle milling • Up Milling (Conventional) & down milling (Climb) – Facing milling • …
Part II—Milling Cutters Set up milling machines to demonstrate facing and peripheral milling operations. Be sure the Chapter 17 The Milling Machine LEARNING OBJECTIVES After studying this chapter, students will be able to: Describe how milling machines operate. Identify the various types of milling machines.
A Side Milling (contouring) operation can be applied to the outside edges of the stock to make sure the part is the proper size. Next, take a look around the edges of the part. There is a shoulder area inside the part boundary that is a minimum of 0.125" wide. It is 0.250" deep. The walls are
Fundamentals of Machining 21.1 Introduction Parts manufactured by casting, forming, and shaping processes often require further operations before the product is ready to use. Features such as smooth shiny surfaces, small-diameter deep holes in a part, threaded section, and threaded holes all require further manufacturing operations.
• The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, shown is the vertical milling machine. • A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.
Milling Fixtures Milling fixtures are the most common type of fixture in general use today. The simplest type of milling fixture is a milling vise mounted on the machine table. However, as the work piece size, shape, or complexity becomes more sophisticated, so too must the fixture. February 26, 2008 29 Milling Fixtures

Face Milling. Face milling is a planar operation used to clean up a flat face of a part. In our example the injection mold needs a flat surface at the parting line. For this class, we will use Face Milling with Boundaries. To use this operation, you define a milling boundary from your part geometry. You can then mill at that level or select a ...

contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the
