Tool Material Selection for Machining
In machining operations, the choice of tool material is crucial to ensure efficient and effective cutting. Various factors need to be considered, such as the workpiece material, cutting conditions, tool life, and cost. In this case, we need to determine the suitable tool material for machining a round steel stock with specific cutting conditions.
Given Data:
- Outside diameter of the steel stock: 100 mm
- Cutting speed: 100 rpm
- Tensile strength of the material: 75 kg/mm2
- Depth of cut: 3 mm
- Feed rate: 0.3 mm/rev
Factors for Tool Material Selection:
1. Cutting Speed: The cutting speed is determined by the rotational speed of the workpiece. Higher cutting speeds require tool materials with better heat resistance and wear resistance.
2. Workpiece Material: The tensile strength of the workpiece material influences the choice of tool material. Harder materials require tool materials with higher hardness and toughness.
3. Depth of Cut: The depth of cut affects the forces acting on the tool. Higher depths of cut require tool materials with good strength and resistance to deformation.
4. Feed Rate: The feed rate determines the rate at which the tool advances into the workpiece. Higher feed rates demand tool materials with good wear resistance.
Analysis:
- The cutting speed is given as 100 rpm. However, the cutting speed in meters per minute (m/min) is required to determine the suitable tool material. We can calculate it using the formula:
Cutting Speed (m/min) = (π * Diameter * RPM) / 1000
Here, the diameter is given as 100 mm, and RPM is given as 100. Plugging in these values:
Cutting Speed (m/min) = (π * 100 * 100) / 1000 = 314.16 m/min
Comparison of Tool Materials:
1. Sintered Carbides: Sintered carbides are known for their high hardness, wear resistance, and toughness. They are suitable for machining applications involving high cutting speeds, high feed rates, and hard workpiece materials. However, they may not be the best choice for machining steel due to its high toughness and tensile strength.
2. Ceramic: Ceramics are characterized by their excellent heat resistance, hardness, and wear resistance. They are suitable for machining applications involving high cutting speeds and hard workpiece materials. Ceramics can withstand the high temperatures generated during machining steel and maintain their cutting performance.
3. HSS (High-Speed Steel): HSS is a common tool material known for its good toughness and wear resistance. However, it may not be the best choice for machining steel at high cutting speeds due to its lower hardness compared to other tool materials.
4. Diamond: Diamond is the hardest known material and has excellent wear resistance. It is suitable for machining applications involving high cutting speeds and hard workpiece materials. However, it is not commonly used for general machining due to its high cost and limited availability.
Conclusion:
Based on the given cutting conditions and the properties of the tool materials, the most suitable tool material for machining the round steel stock would be ceramic. Ceramic tools can withstand the high cutting speeds, hard workpiece material, and maintain their cutting performance due to

Ceramic is correct because ceramic tools should be used for low depth of cut and low feed rate. But, cutting takes place at very high speed.
