Comparative Analysis of Tooling Options for Finish Turning Operation
What are the key parameters to consider when comparing three tool materials for a finish turning operation on steel parts?
Key parameters to consider when comparing three tool materials for a finish turning operation on steel parts are cutting speeds for minimum cost, tool lives, cycle time, cost per production unit, total time to complete the batch, production rate, and the proportion of time spent actually cutting metal for each tooling.
Cutting Speeds for Minimum Cost:
Cemented Carbide: With the Taylor equation parameters provided for cemented carbide (n = 0.25, C = 500), the cutting speed for minimum cost is determined to be 220.63 m/min.
Ceramic: Utilizing the Taylor equation parameters for ceramic (n = 0.6, C = 3,000), the cutting speed for minimum cost is calculated to be 68.28 m/min.
Tool Lives:
High-Speed Steel (HSS): The tool life for HSS is calculated to be 0.918 min.Cemented Carbide: The tool life for cemented carbide is determined to be 0.3684 min.
Ceramic: The tool life for ceramic is found to be 0.1134 min.
Cycle Time:
High-Speed Steel (HSS): The cycle time for HSS is calculated to be 23.11 min.Cemented Carbide: The cycle time for cemented carbide is determined to be 6.51 min.
Ceramic: The cycle time for ceramic is found to be 4.92 min.
Cost per Production Unit:
High-Speed Steel (HSS): The cost per production unit for HSS is calculated based on various factors including tool costs, tool life, and tool change time.Cemented Carbide: Similarly, the cost per production unit for cemented carbide is determined by considering tool costs, tool life, and tool change time.
Ceramic: The cost per production unit for ceramic is calculated based on tool costs, tool life, and tool change time.
