5 times regard space block as ply, undertake trying machining, measure again through 1.
5 Δ E undertakes correction. The ability after be being amended through a few approximates prejudicial cost gradually namely: X=1.
5e+k. X is cushion is large, e is prejudicial value, k is correction, k ≈ 1.
5. Such certainly will arise for many times measure an error, wasteful man-hour is more at the same time. Recommend the little experience in a bit job for this, the real work proof that passes oneself is more feasible method. Set eccentric throw to be E, space block ply is X, 3 ungual clip hold place radius to be R, after the A in figure of figure of X=3/2e-R+(R2-3/4e2)½ of ply of the space block that seek testimony, B, C expresses to fill up thick X, the clip of 3 claw runs a point, d, E, F states the clip that did not fill up thick X runs a point, o runs round actual the centre of a circle for clip, m is prejudicial the centre of a circle after. Argumentation: OThe prejudicial value AD=X that M=e asks namely namely BMO=60 ° of ∠ of OB=R MA=R+X-e MB=MA=R+X-e of space block ply (3 claw are equational 360 ° , ∠ BMC=120 ° ) in triangular BMO: Is negative root of =[(R+X-e)2+e2-R2]/[2e(R+X-e)] 1/2=(R2+X2+e2+2RX-2Re-2eX+e2-R2)/(2eR+2eX-2e2) X2+(2R-3e)X+3e2-3Re=0 X=3/2e-R+(R2-3/4e2)½(of ° of OM) Cos60 of × of BMO=(BM2+OM2-OB2)/(2BM of ∠ of ∠ BMO=60 ° BM=R+X-e OM=e OB=R Cos abandoned go) citing: ?
