Heat transfer is of critical importance in various industrial applications, including manufacturing. During machining, both the cutting tool and the workpiece will be significantly heated by friction heating. The heating of the cutting tool will reduce the tool hardness and strength, deteriorate the cutting quality, and shorten the tool life. Therefore, it is essential to prevent the overheating of the cutting tool during machining. Coolants are an instrumental part of machining to help cool the tool and the workpiece, provide lubricant, flush away chips, and prevent corrosion. The task of this project is to design the coolant to maintain the maximum machine tool temperature below 100°C during the side milling process. As shown in the figure below, the machine tool has a dian of 10 mm (D) and a length of 5 cm. The tool material is M2 high speed tool steel (T11302) and the workpiece is aluminum 6061. The spindle speed (w) is 2000 RPM and the cutting speed (v) is 50 mm/min. The feed force between the tool and the workpiece is 1 kN. The coolant flow properly covers the whole machine tool.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

Heat transfer is of critical importance in various
industrial applications, including manufacturing.
During machining, both the cutting tool and the
workpiece will be significantly heated by friction
heating. The heating of the cutting tool will reduce
the tool hardness and strength, deteriorate the
cutting quality, and shorten the tool life. Therefore,
it is essential to prevent the overheating of the
cutting tool during machining. Coolants are an
instrumental part of machining to help cool the tool and the workpiece, provide lubricant, flush
away chips, and prevent corrosion. The task of this project is to design the coolant to maintain the
maximum machine tool temperature below 100 °C during the side milling process.
As shown in the figure below, the machine tool has a diameter of 10 mm (D) and a length of 5 cm.
The tool material is M2 high speed tool steel (T11302) and the workpiece is aluminum 6061. The
spindle speed (w) is 2000 RPM and the cutting speed (v) is 50 mm/min. The feed force between
the tool and the workpiece is 1 kN. The coolant flow properly covers the whole machine tool.
