Summary: Maths is an application tool, apply extensively at of all kinds course. The article sets out from angle of numerical control process designing, discuss mathematical series knowledge to apply the case at machinist job domain and feasibility to discuss. Keyword: Technology of numerical control of 　 of process designing of series numerical control is digital pilot abbreviation, knowledge of the maths in numerical control process designing is applied more extensive, series has the branch of arithmetical series and geometric series, their commonly used formula is as follows: The N before arithmetical series connects a formulary 　 the N before with 　 geometric series connects a formulary 　 and if 　 uses these formula numerical control language to have a description, can produce very good effect. Group of online sex aperture machines 1 series to if the graph is shown 1 times,apply 　 mediumly, if want,in lieutenant general of numerical control machine tool these 6 Kong Zuan go out, have to decide the coordinate of every aperture above all. These aperture edges show linear to arrange with equal interval point-blank, included angle is spent for #2. The bevel edge that observes the graph discovers these hole not hard is long made an arithmetical series, first are #1, tolerancepublic errand D is #3, the connecting with this aperture long bevel edge formula is #4=#1+[#5-1]*#3 (among them #4 is, #5 is a several N) , angle gave out in together with graph, polar coordinates means is used on the means of process designing (axis of radius of X axis delegate, Y represents point of view) . The program is as follows: To program (FANUC system) bevel edge of the first aperture grows #1=___ of 　 of 　 of G54G000Y0Z50 of 　 of 　 of M03S1000 of 　 of 　 of G40G49G80G90G69G17G15 of 　 of 　 　 O0001 　 #5=_1_ of 　 of 　 of span of #3=___ aperture of 　 of 　 of included angle of 　 　 #2=___ machines 　 of 　 of the first aperture above all the gross of #6=___ aperture, the G01X#4Y#2F1000 of 　 of bevel edge long 　 that enters aleatoric hole of #4=#1+[#5-1]*#3 of 　 of 　 of circular 1 locates 2 series of 　 of 　 of M30 of 　 of 　 of M05 of 　 of G00Z200 　 of 　 of 　 of G15 of 　 of 　 of END1 of 　 of #5=#5+1 　 of 　 of 　 of G98G81R#7Z#8F1000 of 　 of 　 of opening position upper part are in treatment of annular aperture group is medium, write an edge circumferential all the aperture group of cloth, coordinate of the centre of a circle is process designing origin namely. Round radius of this graph reference circle is #3, the first aperture and X axis included angle are #1, interval of the angle between each aperture is #2, kong Shu is 10 aperture, direction adopts the provision of numerical control machine tool, the regulation is anticlockwise for square to, suitable hour hand is negative direction. The program is as follows: To program (FANUC system) the #5=_1_ of 　 of 　 of radius of reference circle of #3=___ of 　 of angle increment 　 of aperture machines the #2=___ of 　 of 　 of initial point of view of #1=___ aperture of 　 of 　 of G54G000Y0Z50 of 　 of 　 of M03S1000 of 　 of 　 of G40G49G80G90G69G17G15 of 　 of 　 of 　 　 O002 above all the gross 　 　 of aperture of #6=_10_ of 　 of 　 of the first aperture #7=___ R dot, the G01X#3Y#4F1000 of 　 of horny degree 　 that enters aleatoric hole of #4=#1+[#5-1]*#2 of 　 of 　 of circular 1 locates aperture of #5=#5+1 of 　 of 　 of bore of G98G81R#7Z#8F1000 of 　 of 　 of opening position upper part counts independent variable to increase by degrees END1 of 　 of an unit 　 circulates G15 of 　 of 1 end 　 cancels polar coordinates, in O0001 program, independent variable is grow with bevel edge changing, angle is changeless. In O0002 program, independent variable is angle is changing with arithmetical series, radius is changeless. First are #1, tolerancepublic errand D is #2, of this aperture angle connect a formula to be #4=#1+[#5-1]*#2 (among them #4 is, #5 is a several N) . CNC Milling CNC Machining
