Answer:
To determine the suitable tool material for machining the round steel stock, we need to consider the cutting conditions and the material properties.
Cutting Conditions:
- Outside diameter of the round steel stock: 100 mm
- Rotational speed: 1000 rpm
- Depth of cut: 3 mm
- Feed rate: 0.3 mm/rev
Material Properties:
- Tensile strength: 75 kg/mm2
Tool Materials:
a) Sintered carbides
b) Ceramic
c) HSS (High-Speed Steel)
d) Diamond
Criteria for Suitable Tool Material:
The tool material should have high hardness and wear resistance to withstand the cutting forces and high temperatures generated during machining. It should also have sufficient toughness to withstand the impact and shock loads. Additionally, the tool material should have good thermal conductivity to dissipate the heat generated during machining.
Explanation:
- Sintered carbides: Sintered carbides are known for their high hardness and wear resistance, making them suitable for machining hard materials. However, they have poor toughness and may not withstand the impact loads encountered during machining the round steel stock.
- HSS: High-Speed Steel is a versatile tool material with good toughness and wear resistance. It is commonly used for machining a wide range of materials. However, for the given cutting conditions and the tensile strength of the round steel stock, HSS may not provide sufficient hardness and wear resistance.
- Diamond: Diamond is the hardest known material and has excellent wear resistance. However, machining with diamond tools requires high cutting speeds and low feed rates. The given cutting conditions do not match the requirements for diamond tooling.
- Ceramic: Ceramics have exceptional hardness, wear resistance, and high-temperature resistance. They can withstand high cutting speeds and provide excellent surface finish. Based on the given cutting conditions and the material properties, ceramic tooling is the most suitable option.
Therefore, the suitable tool material for machining the round steel stock under the specified cutting conditions is ceramic.
