Challenges and solutions in achieving geometrical accuracies in machining - IMTMA/P029



Programme Background

Achieving required level of geometrical accuracies - consistently, on machined parts, is a regular challenge faced by the Production Engineers and Process Planning Engineers. This requires an integrated approach encompassing the Machine Tool, Fixtures, process parameters and to some extent, Tool Holders and Part materials.

With primary focus on the frequently occurring problems on the Shop Floor in this area, we develop a systematic framework of investigation and iteration procedure by which the errors could be minimized.

Focus Areas
  • Machine Tool main spindle - the starting point of our journey
  • Chuck types - Suitability with reference to accuracy levels - Chuck setting
  • Selection of "part clamping and resting areas" based on "part drawing tolerance references"
  • Relation between "as presented condition" and "as comes out condition"
  • Concentricity and radial run-out
  • Axial tolerances
  • Part "Clamping force" and "Torque"
  • Why part slips in ER collets
  • Self-Centering ID clamping
  • Thin wall part clamping
  • Clamping on irregular surface
  • Turn Mill Center (Live Tools) advantages - Live Tool Holder Check points
  • Hard Part Turning care points
  • Machining Center Fixtures - Part repositioning tolerances
  • Machining center Fixtures for multiple part clamping
  • Modular re-usable design concepts for machining center fixtures
  • Fast Set Up change over systems (QCO)
  • Illustrations through examples

Our Initiatives

Productivity Institute

The need for Productivity Institute

  • Is your work place suffering from poor productivity?
  • Do you feel that supervision is weak on the shop floor?
  • Do your shop floor personnel find it difficult to achieve targets?
  • You have the machine in place, but not the men to optimize usage?
