Methods to Remove Tool Marks in Turning Process for Custom Machined Parts:

  1. Optimize Cutting Parameters:
    • Reduce feed rate: Lowering the feed rate can reduce the depth of tool marks, thus minimizing their visibility.
    • Increase cutting speed: A higher cutting speed can reduce friction between the tool and the workpiece, resulting in a smoother surface.
    • Minimize tool wear: Using sharp tools helps reduce tool marks. Regularly inspect the tools for wear and replace them as needed.
  2. Use Appropriate Tool Geometry:
    • Increase tool nose radius: A larger tool nose radius will smooth the cutting process and reduce surface tool marks.
    • Adjust tool relief angle: An appropriate relief angle reduces pressure and friction on the workpiece surface, improving the surface quality.
  3. Utilize Finishing Tools and Methods:
    • Use finishing tools: Finishing tools offer better surface quality.
    • Secondary finishing (deburring): After rough machining, use lower feed rates and cutting depths for finishing to refine the surface.
  4. Use Oilstone or Abrasive Cloth for Polishing:
    • After turning, light polishing with an oilstone or abrasive cloth can effectively remove residual tool marks, improving the surface finish.
  5. Apply High-Pressure Coolant:
    • High-pressure coolant helps to wash away chips effectively, reducing secondary cutting. Its lubricating properties also lower surface friction and reduce tool mark formation.
  6. Polishing Treatment:
    • Perform post-process polishing, such as mechanical polishing, liquid polishing, or electrochemical polishing, to further improve surface quality and remove fine tool marks and roughness.

By applying these methods and selecting appropriate processes and tools based on the material and machining requirements, tool marks can be minimized or eliminated, resulting in high-quality surface finishes.
