Grahic Jump Location
Spindle error motions measurement (Proximity sensors P1−P4 are used to measure the axial runouts of the master. Proximity sensors P4−P7 are used to measure the radial runouts of the master. Angular positions ϕ23 are used to define the sensor configuration.)
Grahic Jump Location
Experimental setup for spindle error motions measurement. (Sensors P4−P6 are not shown.)
