MECHANICAL CONTROL

  • Controls can be of two types:
               mechanical
               magnetic
     
  • Depending on the type of part, the quantity of parts that has to  be produced, MMC determines the original mode of mechanical control.
     
  • The main modes of control are:
               - Control plane with conventional metrology
               - 3D control
               - Inspection gauge, Type GO NOGO
     
  • Checks may be unitary, by taking 100%...

 

MAGNETIC CONTROL

The magnetic control must be forecasted at the beginning because most of the time, it is made from « witness washers » issued from the same material as the parts and placed in the same heat treatment.
Magnetic control on washers lets you know: μi, μmax, Hc, Bs
It is necessary to know whether the measure should be made continuous or alternating.
