| Summary: | This paper presents a joint use of the T2 chart and total inertial tolerancing
for process control. Here, we will show an application of these approaches in the case of
the machining of mechanical workpieces using a cutting tool. When a cutting tool in
machining impacts different manufactured dimensions of the workpiece, there is a
correlation between these parameters when the cutting tool has maladjustment due to bad
settings. Thanks to total inertial steering, the correlation structure is known. This
paper shows how T2 charts allow one to take this
correlation into account when detecting the maladjustment of the cutting tool. Then the
total inertial steering approach allows one to calculate the value of tool offsets in
order to correct this maladjustment. We will present this approach using a simple
theoretical example for ease of explanation. |
