What is Precision Machining?

August 15, 2016

Precision Machining is the process of removing material from a workpiece while holding close tolerance finishes. The precision machine has many types, including milling, turning and electrical discharge machining. Precision machining from a Toronto business is best described by a precision machining engineer, "The basic idea is that machine tools obey cause and effect relationships that are within our ability to understand and control and that there is nothing random or probabilistic about their behavior. Everything happens for a reason and the list of reasons is small enough to manage."

Precision machining from our Toronto shop achieves the following:

  • Highly precise movement
  • Reducing the dispersion of the product's or part's function
  • Eliminating fitting and promote assembly, especially automatic assembly.
  • Reducing the initial and running cost
  • Extending the product’s life span
  • Enabling the design safety factor to be lowered

The combined characteristics of the machine tool and the control determine the precision of rpositioning. Three critical measures of precision are: resolution, accuracy, and Repeatability. Accuracy of a CNC system depends on the resolution, the computer control algorithms, and the machine inaccuracies. Repeatability is a statistical term associated with accuracy. It refers to the capability of a positioning system to return to a programmed point, and is measured in terms of the errors associated with the programmed point. Cutting tool deflection, machine tool chatter, mechanical linkage between the leadscrew and the tool, and thermal deformations are the chief contributing factors in machining inaccuracy.
