7 Introduction to Machining Source: Kalpakjian 2000
8 Introduction to Machining Comparison of specific energies between machining and grinding (Unit HP/in. 3 /min) Material Machining Grinding Aluminum Class 40 Gray Iron Low Carbon Steel Titanium Hardened Tool Steel (67 Rc) Source: Kalpakjian 2000
9 Introduction to Machining How to realize high efficiency machining? 1. Increasing machining/grinding speed 2. Increasing DOC, feedrate, etc. 3. Reducing machining downtime (tool change, wheel truing/ dressing, workpiece setup, machine setup, workpiece transfer, etc.) Source: Kalpakjian 2000
10 High Speed Hard Turning Source: Beard 2001, MS Online
11 High Speed Hard Turning Hard Turning vs. Conventional Turning Advantages Short cycle times; Low cost to machine investment; High accuracy if the green part is accurate; Good surface finishes; Machining heat mostly dissipated with the chips; High material removal rate (2-4 times); Multiple operations in a single chucking; Good for wet or dry cutting. Disadvantages Fast tool wear; High stiffness and high speed machine tools; Advanced machine controller; Good tool holder for high speed (e.g., dynamic balance and chucking); Advanced cutting tool materials and coatings.

13 High Speed Hard Turning Centrifugal force 2 F c m r Clamping tight enough? Example: F=1,000 N at 3,000 rpm F=100,000 N at 30,000 rpm Source: Beard 2001, MS Online
14 High Speed Hard Turning Cutting Tools Tool strength vs. geometry Example: To soften a workpiece for an easy material removal, nickel alloys are better cut at about 1,200 C. Choosing right tool material (e.g. CBN and SiC whisker reinforced Al 2 O 3 ) and machining conditions (speed, feedrate, DOC) is critical. Source: Koepfer 2001, MS Online
15 High Speed Peel Grinding High-speed peel grinding with narrow superabrasive wheels Parallel axis Tilt axis Source: Koepfer 2001
16 High Speed Peel Grinding Advantages of HSP over Conventional Grinding High speed (up to 200 m/sec) for high efficiency; High material removal rate (up to 100 mm 3 /mm/s); Reduced grinding forces (less critical to machine stiffness); Reduced area of contact with the workpiece; Easier coolant delivery to the grinding zone; Larger G-ratio (up to 6000); Multiple operations in a single setup of the workpiece. Source: Luetjens 2004
17 HSP Grinding vs. Hard Turning For workpiece materials too hard or flexible to turn; For workpieces of different materials in different sections; Insensitive to breakage of individual cutting edges; Better surface finish and surface quality; Better geometric tolerance control due to spark-out capability to kiss workpiece surface.

18 High Speed Spindle Component Motorized spindle with hybrid ceramic bearings Motorized spindle Hybrid ceramic bearing
19 High Speed Spindle Component Comparison among the high speed spindles Bearing type Rolling element Magnetic Aerostatic High static and High speed due to large bearing High dynamic stiffness dynamic stiffness gap Low frictional loss Pros Simple structure Low cost Very low frictional loss Very high static stiffness Bearing characteristics highly High rotational accuracy controllable On-line monitoring of bearing conditions from bearing sensors High frictional loss Low dynamic stiffness Low static stiffness Cons Periodic maintenance needed Complicated structure High cost Low load capacity Contamination due to lubrication Source: Suzuki and Yamada 2001

23 Linear Motor vs. Ballscrew Drives Source: Hyatt
24 Linear Motor vs. Ballscrew Drives Source: Copley Controls
25 Linear Motor vs. Ballscrew Drives Drive type Pros Cons Linear Motor Easy to operate at high speed and high acceleration; Less maintenance even at high speed and high acceleration operations; Easy to achieve fast and accurate positioning because of direct drive; Higher dynamic stiffness and servo bandwidth; Unlimited stroke. Lower thrust under a given limitation of stage size; Higher cost; Difficult application (pulling force is 3 times of pushing force); Non stop in case of power loss, crushing problem. Ballscrew Larger thrust under a given limitation of stage size; Lower cost due to mass production; Optimal deceleration during loss of power; Better damping effect to minimize chatter. Limited Speed and acceleration; Frequent maintenance if operated at high speed and acceleration due to wearing Lower dynamic stiffness due to backlash; Difficult positioning due to backlash; Limited stroke.
26 Future Topics Engineered machining tools; Modern machines (e.g., fewer components, light and stiff structure); Intelligent machines (nanostructured sensors; sensor fusion, etc.); New cutting tool materials and coatings.
27 Future Topics Milling/ Turning??? Grinding
28 Future Topics Hard fiber/ whiskers Hard fiber/whisker wheel Quick change mechanism to allow for 1 m radial runout
29 Concluding Remarks HEM/HSM is an everlasting topic. Grinding and Milling will merge into a single whole. Today s HEM/HSM will be regarded as tomorrow s conventional machining. HEM/HSM always represents the fastest, most efficient and inexpensive machining technology of its era.
