WAM336數控磨床電器系統(tǒng)技術改造
| WAM336數控周邊磨床主要用于磨削各類具有直線面和圓弧面的硬質合金可轉位銑刀片。根據改造后的機床特點和加工要求，我們編制了磨削直線面和圓弧面的工藝宏程序。 磨削直線面的宏程序 磨削直線面的宏程序(9011)如下： %LINE，MX， (SUB 9011) (WRITE G54) (WRITE G90 G0 XP21) (WRITE G90 G0 CP0) (WRITE G90 G0 BP11) (P25 = P1 + 1) (WRITE G90 G0 XP25) (P15 = P1 + ORGX54*(1-1 / COS(P11))) (WRITE G90 G1 XP15 FP20) (WRITE G4 KP23) (WRITE G90 G0 XP21) (WRITE G91 G0 CP2) (WIRTE G90 G0 BP12) (P24 = P3 + 1) (WRITE G90 G0 XP24) (P16 = P3 + ORGX54*(1-1 / COS(P12))) (WRITE G90 G1 XP16 FP20) (WRITE G4 KP23) (WRITE G90 G0XP21) (WRITE G91 G0 CP4) (WRITE G90 G0 BP13) (P22 = P5 + 1) (WRITE G90 G0 XP22) (P17 = P5 + ORGX*(1-1 / COS(P13))) (WRITE G90 G1 XP5 FP20) (WRITE G4 KP23) (WRITE G90 G0 XP21) (WRITE G91 G0 CP6) (WRITE G90 G0 BP14) (P19 = P7 + 1) (WRITE G90 G0 XP19) (P17 = P7 + ORGX54*91-1 / COS(P14))) (WRITE G90 G1 XP17 FP20) (WRITE G4 KP23) (P0 = 0，P1 = 0，P2 = 0，P3 = 0，P4 = 0，P5 = 0，P6 = 0，P7 =0，P8 = 0，P9 = 0，P10 = 0，P11 = 0，P12 = 0，P13 = 0，P14 =0，P15 = 0，P16 = 0，P17 = 0，P18 = 0，P19 = 0，P20 = 0，P21= 0，P22 = 0，P23 = 0，P24 = 0，P25 = 0) (RET) 加工實例 現以磨削加工如圖所示刀片為例，說明如何調用宏程序SUB9010、SUB9011 和建立演算子程序。 該刀片需要加工的尺寸包括二個直線面(14mm×7mm)和四個圓弧面(4-R2mm)。根據工藝要求，首先磨削直線面，再依次磨削圓弧面。刀片初始上料角度為0°。編制演算子程序如下： (OPEN P8000，D) (WRITE(SUB 8000)) (PCAL9011，P0 = 0，P1 = 3. 50，P2 = 90°，P3 = 7. 00，P4 =90，P5 = 3. 50，P6 = 90°，P7 = 7. 00，P20 = 8，P21 = 12，P23= 100°) (PCALL9010，P0 = 270°，P1 = 5. 00，P2 = 1. 5，P3 = 2，P4 =90°，P7 = 0，P12 = 0.1，P20 = 100，P21 = 12°) (PCALL9010，P0 = 360，P1 = 1. 5，P2 = 5，P3 = 2，P4 = 90，P7 = 0，P12 = 0.1，P20 = 100，P21 = 12°) (PCALL 9010，P0 = 450°，P1 = 5.00，P2 = 1. 5，P3 = 2，P4 =90°，P7 = 0，P12 = 0.1，P20 = 100，P21 = 12°) (PCALL 9010，P0 = 540°，P1 = 1. 5，P2 = 5，P3 = 2，P4 =90°，P7 = 0，P12 = 0.1，P20 = 100，P21 = 12°) (WRITE(RET)) M30 將編制好的演算子程序在機床中運行，生成一個新的磨削子程序P8000。在實際加工中，將P8000連接到主程序中即可實現刀片的磨削。 呼叫一次SUB9011 宏程序可完成磨削四個直線面的加工程序編制。在實際應用中，可根據圖紙和工藝要求，通過在演算子程序中連續(xù)呼叫SUB9011宏程序來完成磨削任意直線面的加工編程。為此，首先需要建立一個演算子程序(即呼叫子程序)，然后在該程序中對參數進行賦值，即可完成加工程序的編制。需要賦值的參變量包括：初始上料角度P0，磨床第一邊半徑尺寸P1，磨削第二邊外夾角P2，磨削第二邊半徑尺寸P3，磨削第三邊夾角P4，磨削第三邊半徑尺寸P5，磨削第四邊外夾角P6，磨削第四邊半徑尺寸P7，第一邊到第四邊的后角P11～P14，磨削速度P20，外接圓半徑P21，空磨時間P23。 磨削圓弧面的宏程序 磨削圓弧面的宏程序(9010)如下： %CYCLE，MX， (SUB 9010) (WRITE M7) (WRITE G5) (WRITE G90 G1) (P24 = P0) (P25 = SQRT (P1*P1 + P2*P2)) (P23 = P7) (P19 = P23) N10(P20 = P3 - P25) (IF P20 GT 0 G0T0 N30) (P23 = - P7 - ACOS(P1 / P25)) (P19 = P23) N20(P22 = P25*COS(P23)+ P3) (WRITE F10) (WRITE XP22) (WRITE F100) (WRITE CP24) N25(P22 = P25*COS(P23)+ P3) (WRITE XP22 CP24) (P23 = P23 + P12) (P24 = P24 + P12) (IF P23 LE(P19 + P4)GOTO N25) (RET) N30(P23 = P7) (P19 = P23) (P22 = - P25*COS(P23 + P3) (WRITE F10) (WRITE XP22) (P18 = P24 + 90 + P7) (WRITE F100) (WRITE CP18) N35(P22 = - P25*COS(P23)+ P3) (WRITE XP22 CP18) |
