The different precision machining technologies


Precision machining is a field that incorporates many technologies that have been implemented as science has progressed. These advances make it possible to manufacture parts with ever-increasing precision in less time.

Discover some of the different technologies that have transformed the machining of mechanical parts.

High-speed machining (HSM)

High-speed machining (HSM) refers to machining processes where the cutting parameters are far superior to those used in traditional machining. Generally speaking, a machining process is defined as “high-speed” when the cutting speed is two to three times faster than in conventional machining.

 Limitations of HSM

The safe and profitable incorporation of HSM in a custom gear shop requires additional constraints to be respected.

Although the increase of speed may seem simple, the physical mechanisms involved in this technology are not the same as in traditional machining. Machining parameters affect cutting forces, the temperature reached on the machined surface and in the tool, tool wear, and more. Moreover, other practical problems such as vibrations, chips being discharged, the use of lubricants during machining, and many others, must be considered and adapted.

Advantages of high-speed precision machining

Despite the complexity and limitations of HSM, it provides significant benefits in terms of technical and economic performance:

  • A virtually perfect surface from roughing to finishing, thus reducing polishing and grinding time
  • Increased dimension precision
  • Easier repetition, allowing for larger production quantities
  • Machining of ultra-hard materials
  • Machining more complex shapes and thinner walls
  • Reduced manufacturing time, which increases productivity

Laser assisted machining (LAM)

Laser assisted machining (LAM) involves heating only the area to be machined without thermal diffusion, which which could result in changing the mechanical characteristics of the part. This method is particularly suitable for steels and other high-strength metals.

Limitations of LAM

Particularities such as heating optimization, the quality of the generated surfaces, finding suitable tools, reducing specific cutting forces to facilitate machining and the possibility of working with non-machining materials are all issues that make LAM relatively complex to implement.

Advantages of LAM

Despite the complexities associated with developing LAM, its advantages bring precision machining to the next level:

  • Minimized cutting efforts
  • Highly improved surface conditions
  • The ability to machine parts using so-called “impossible to machine” materials
