Step S40, adjusting module 106 according to specifying the coordinate of specification tolerance to point each in the first coordinate queue to adjust, obtains the second coordinate queue on adjusted direction.The described formula according to specifying specification tolerance to adjust the first coordinate queue is as follows, X2=I*Dx+X1, Y2=J*Dy+Y1, Z2=K*Dz+Z1, wherein, X2, Y2 and Z2 are that after adjustment, the sequential method of the second coordinate queue mid point is to vector value in three axial directions, and I, J and K are the actual normal direction vector value in three axial directions of point, X1, Y1 and Z1 be adjust front first coordinate queue mid point sequential method to vector value in three axial directions, Dx, Dy and Dz are tolerance numerical value in three axial directions.It should be noted that, specify the quantity of specification tolerance identical with the quantity of the second coordinate queue, such as, if the quantity of specifying specification tolerance (i.e. Dx, Dy, Dz) is five, then the quantity of the second coordinate queue is also five.Producers can pass through the coordinate that tolerance (i.e. Dx, Dy and Dz) adjusts the first coordinate queue mid point, namely the coordinate of the first coordinate queue mid point is amplified in the actual point normal direction positive dirction of each point, or the actual point normal direction negative direction of each point reduces the coordinate of the first coordinate queue mid point, thus obtain one or more second coordinate queue.
Step S50, generation module 102 generates new job sequence according to the second coordinate queue.Specifically, by the value in the second coordinate queue, substitute the coordinate figure in original job sequence, thus generate new job sequence.For example, the numerical value of coordinate points each in Fig. 4 is replaced with the numerical value in the second coordinate queue, thus generates new job sequence.If the second coordinate queue is five, then the job sequence that generation five is new.
After generating new job sequence, user can specify specification tolerance produce the part of different size according to adjustment, thus reaches mating of Equipment Part and assembly, thus reaches and avoid production bad.For example, after some Equipment Parts (as: metal shell) are produced, specification is fixing, due to the reason manufactured, Equipment Part cannot reach the theoretical precision of 100%, if now assembly (as: plastic fittings) produces a kind of specification according to drawing, then possibly cannot mate with assembly parts, if user is according to the assembly of specifying specification tolerance to generate one or more specification, can realize realizing to greatest extent mating of assembly parts and assembly, that avoids on producing is bad.
