In the line cut treatment that waits for example in mould, electrode, basically use format of automatic programming language to weave program. The example cut that comes a few years formed such structure in treatment: The key of cut mould example is in process designing, and the difficulty of process designing is being calculated. Have some of more complex model, odd the program is as high as a few, computation comparatives loaded down with trivial details. Need computation to be located by two to program of certain work out dimension line (or its extension line) when intersect and forming nodical coordinate, artificial computation appears quite difficult, and if can use the computer to assist computation, meet be readily solved, get the result of get twice the result with half the effort. Be like the model that plan institute shows, when work out program, to line segment AQ, QC, of the coordinate that wants computational Q place and diagonal QC and X axis to included angle β (or the coordinate) that C nods. By the graph knowable, place of line segment QC is R12 point-blank.

75mm circular arc and  91.

The common tangent of 4mm circle, c dot is this common tangent and R12.

The point of tangency of 75mm circular arc, d dot is this common tangent and 91.

The point of tangency of 4mm circle, q dot is height for 56.

The node of 9/2mm height line and this common tangent. Computational process is as follows: If the graph takes calm coordinate department, cross R12.

O1 of 75mm the centre of a circle makes O1M ∥ QC, hand in X axis to be nodded at M; Cross O1 to make rod of O1N ⊥ X, n is hang down sufficient; Join OD, criterion OD ⊥ QC, OD ⊥ O1M, hang down sufficient for P. Cross Q to nod QE ⊥ Q1M, e is hang down sufficient; Make rod of QG ∥ X, hand in O1N to be nodded at G. Set ∠ MO1N= α , criterion α of FQE= of ∠ POM= ∠ . There is following concern below graphic representation condition: Relation of recombine trigonometric function solves the binary quadratic equation that this couplet establishs, get α =4.

6484 ° , criterion of diagonal QC and X axis ° of =90 of β of Xiang Ga horn - α =85.

3516 ° . The abscissa that Q of recycle α computation nods. In Rt=12.

792076. The abscissa XQ=-(QF+FG+NO)=-43 that Q nods.

542169, know the ordinate YQ=56 that Q nods by the graph.

9/2=28.

45, the coordinate that A nods is (- 48.

45, 23.

2) , criterion the program of line segment AQ, QC is: AQ: B1 -48.

352 　 see this computation comparative loaded down with trivial details, and benefit assists computational process designing with the computer, appear handy got more. Still take department of coordinate of former graphic representation, weave the program is: Get the abscissa that Q nods above all, will " examination " key presses, make the program moves, q nods ordinate, YQ=56.

9/2=28.

45, when CRT  screen shows Y=028450, write down right now the indication value X=-043542 of X, namely the abscissa that Q nods, for XQ=-43.

542. Make the program continues to run terminus next, namely C of point of tangency, its show indication to be: , namely the coordinate that C nods is (- 42.

45, 41.

782) . So far, line segment AQ, QC nods coordinate to be A(-48 each.

782. Assist computational process designing through using the computer, but relatively simplify substantially the artificial computation of loaded down with trivial details, went to the lavatory process designing, be helpful for production. CNC Milling CNC Machining
