1. High Speed Machining

2. What is ………..Metal Cutting? Precision Remove un-necessary parts. Just as needed……..

3. How to achieve precision metal casting? 2)Software: Smart and intelligent to reduce tool wear 1)Machine: Accuracy of move and position (0.001mm) Sufficient rigidity to let cutting tool to cut at required position 3)Tooling: Concentricity and dimensional accuracy (0.005mm) to avoid excessive vibration Sufficient ability to sustain under high temperature (1100 degC) Sufficient hardness (Hv3200) Sufficient rigidity to avoid tool rebound during engaging

4. High Efficiency Machining Trend Coolant Material Removal Rate per minute (cc/min) '90'91'92'93'94'95'96'97'98'99 2000 - Cutting Feed(V) (m/min) ~10 (0.6in 3 /min) 30~60 (98~197SFM) 300~600 (984~1969SFM) HRC50 10~3 0 60~150 HRC60 Oil High cutting feed 、 High efficient machining 、 High hardness machining 、 Dry cutting Introduction 100~200 (328~656SFM) ~30 (1.8in 3 /min) ~50 (3.0in 3 /min) FluidMist

5. High Speed Cutting Primary Shear Zone High temperature produced by sliding against each other Cutting tool can take out the high temperature by the chip formed Primary shear zone is under a plastic deformation and annealing status, and thus lowering the cutting resistance force Flute Workpiece

6. How heat is dissipated during high speed cutting 75% Taken out by chip and mist Taking out by cutter 5% Absorb by workpiece 20%
