Multiobjective Optimization of Cutting Parameters for TA10 Alloy Deep-Hole Drilling

Area of Science:

• Materials Science and Engineering
• Manufacturing Processes
• Mechanical Engineering

Background:

• The Boring and Trepanning Association (BTA) deep-hole drilling process is crucial for producing high-quality TA10 pipes.
• Challenges include difficult chip removal, tool wear, and poor surface finish, impacting efficiency and quality.

Purpose of the Study:

• To optimize process parameters for TA10 deep-hole drilling.
• To improve chip removal, reduce tool wear, and enhance hole surface quality.

Main Methods:

• Conducted deep-hole drilling experiments on TA10 workpieces with a specifically designed tool.
• Varied process parameters (spindle speed, feed rate) to analyze their impact.
• Evaluated outcomes based on chip morphology, tool wear, hole-axis deflection, and surface roughness.

Main Results:

• Higher feed rates led to smoother chip removal.
• Lower spindle speeds resulted in reduced tool wear and less hole-axis deflection.
• Optimal parameters (145 r/min spindle speed, 0.12 mm/r feed) achieved desired roughness and machining efficiency.

Conclusions:

• Process parameter optimization is critical for TA10 deep-hole drilling.
• Achieved a balance between machining efficiency and surface accuracy through parameter tuning.
• The study provides optimal settings for producing high-quality TA10 pipes using BTA drilling.
