No Perfect Drawing? How CNC Parts Can Still Be Manufactured Correctly

Many customers believe CNC machining requires 100% complete drawings.
In reality, most real projects start with incomplete information.

Common situations:

• Old parts with no original drawings
  
  

• Hand sketches without tolerances
  
  

• 3D models without material or surface specs
  
  

• Samples with unknown heat treatment
  
  

How professional CNC suppliers handle this:

• Reverse engineering using sample measurement
  
  

• Functional surface identification
  
  

• Engineering confirmation before machining
  
  

• Machining test pieces for validation
  
  

By focusing on function first, not paperwork, CNC parts can be:

• Reproduced accurately
  
  

• Improved structurally
  
  

• Optimized for longer service life
  
  

CNC machining is an engineering process, not just a drawing-following task.
