Apply grand function instruction to machine process designing of dimensional curve CNC Milling

46 are shown. Bottom land is the circular arc of R ＝ 5mm. For program of convenient work out, use error of interpolation of oversight of rough differential method to machine. It is variable with angle X, take photograph adjacent the X between 2 o'clock to equidistant, span is 0. 5 ° , use 35sinX of ＝ of sinusoid equation Y and Z ＝ 5sinX to be calculated respectively next the Y value that gives correspondence each a little bit and Z value, have a space linear interpolation, approach dimensional curve with the space point-blank. Ball head milling cutter is used when treatment (R ＝ 5mm) in one plane the milling on hypostatic spare parts gives slot of curve of this one space. Setting of treatment coordinate department sees a picture 4.

The setting maintains model variable: #500- - Z to every time approach is 2mm; The input when the setting " 2000 " ; #501- - the amplitude of Y ＝ 35sinX is 35mm, the input when the setting " 35000 " ; #502- - the amplitude of Z ＝ 5sinX is 5mm, the input when the setting " 5000 " ; #503- - the step pitch of X is 0. The terminus when 5 ° is worth 360 ° ; The input when the setting " 360. " . Install operation variable: #100- - X is worth currently, to spend; #110- - Y coordinate is worth currently, for Mm; #120- - the value of Z ＝ 5sinX, for Mm; #130- - Z to every time the initiative value after feed, for Mm; #140- - Z coordinate is worth currently, for Mm.

N140 is the coordinate cost cutting that goes out by computation a paragraph of space is linear, with approach dimensional curve point-blank. N150 is the terminal differentiate that dimensional curve ends, with X ＝ 360 ° are terminus, if did not arrive, return N100 to be calculated again below a bit coordinate; If already arrived, end a subprogram.
