Model : Canna/Caviar
Drawing No. : 1061380-01
Dimension 1 : (E) 530 +0/-0.6 (L)
Coordinate 1 : E-6
Dimension 2 : 16.2 +0/-0.1 Left & Right side (no character)
Coordinate 2 : E-2 & E-10
Specification data
Part name : Housing Upper
Part code : 1061379-00
Model : Canna/Caviar
Drawing No. : 1061379-01
Dimension 1 : 531 +0.4/-0.2 (no character)
Coordinate 1 : F-5
Dimension 2 : 17 ±0.22 Left & Right side (no character with general tolerance)
Coordinate 2 : F-1 & F-9
Specification data comparison for Out-side Line (green line)
Cover Printer : >> 530.6 Housing Upper : >> 531.4
<< 530 << 530.8
Risk assesment for probably stuck assy by maximum dim of Cover Printer VS minimum dim of Housing Upper is OK.
Check point : 530.8 - 530.6 = 0.2 gap
Specification data comparison for In-side Line (red line)
Cover Printer dim a : Housing Upper dim b :
>> 530 - (16.2 + 16.2) = 497.6 >> 531.4 - (17.22 + 17.22) = 496.96
<< 529.4 - (16.1 + 16.1) = 497.2 << 530.8 - (16.78 + 16.78) = 497.24
<> 529.4 - (16.2 + 16.2) = 497 <> 530.8 - (17.22 + 17.22) = 496.36
>< 530 - (16.1 + 16.1) = 497.8 >< 531.4 - (16.78 + 16.78) = 497.84
Risk assesment for probably stuck assy by minimum dim a VS maximum dim b is NG.
Check point : 497 - 497.84 = -0.84 overlap
Actual data dimension for Cover Printer by 30 shoots Actual data dimension for Housing Upper by 30 shoots Data match test
