Cutting speed effects tool life greatly. Increasing cutting speed increases cutting temperature and results in shortening tool life. Cutting speed varies depending on the type and hardness of the work material. Selecting a tool grade suitable for the cutting speed is necessary. E TJ 4) O) c 500 400 300 200 100.

Increasing cutting speed by 20% decreases tool life by 50%. Increasing cutting speed by 50% decreases tool life by 80%. 2. Cutting at low cutting speed (20-40m/min) tends to cause chattering. Thus tool life is shortened. Q005 TECHNICAL DATA EFFECTS OF CUTTING CONDITIONS FOR TURNING EFFECTS OF CUTTING CONDITIONS Ideal conditions for cutting are short cutting time long tool life and high cutting accuracy. In order to obtain these conditions selection of efficient cutting conditions and tools based on work material hardness shape and machine capability is necessary. CUTTING SPEED
