Specific work process is as follows: when carrying out turnery processing, by Cutting Force, Cutting Force warp at the point of a knife of lathe tool blade
Lathe tool knife bar acts on four rectangular flexible substrates, so that the middle part of lathe tool knife bar and four rectangular flexible substrates generations are biggish
Stress, so that deformation occurs for the middle part of lathe tool knife bar and four rectangular flexible substrates, so that four thin film sensors
Deformation occurs.At this point, since the output signal of four thin film sensors is inconsistent, so that Wheatstone bridge module is in non-equilibrium
State, thus output voltage signal, the voltage signal are transmitted to Wheatstone bridge module after signal processing module is handled
