Wonke umntu uqhelene nomsonto. Njengabalingane kushishino lokuvelisa, sihlala sifuna ukongeza imisonto ngokweemfuno zabathengi xa kusetyenzwa izincedisi zehardware ezifanaCNC Machining iindawo, CNC ukuguqula iindawokwayeCNC milling iinxalenye.
1. Yintoni umsonto?
Umsonto yiheliksi esikwe kwisixhobo sokusebenza nokuba sivela ngaphandle okanye ngaphakathi. Imisebenzi ephambili yemisonto yile:
1. Yenza uxhulumaniso lomatshini ngokudibanisa iimveliso zentambo yangaphakathi kunye neemveliso zentambo zangaphandle.
2. Dlulisela isindululo ngokuguqula intshukumo ejikelezayo ukuya kwintshukumo yomgca kwaye ngokuphambeneyo.
3. Fumana inzuzo yoomatshini.
2. Iprofayili yomsonto kunye nesigama
Iprofayili yomsonto imisela ijometri yomsonto, kuquka i-diameter ye-workpiece (enkulu, i-pitch, kunye ne-diameter encinci); i-engile yeprofayili yomsonto; i-pitch kunye ne-helix angle.
1. Amagama omsonto
① Ezantsi: Umphezulu ongezantsi odibanisa imisonto emibini esecaleni emeleneyo.
② iflenki: umphezulu wecala lomsonto odibanisa i-crest kunye nomzantsi wezinyo.
③Crest: Umphezulu odibanisa amaflanki amabini.
P = inowuthi, mm okanye imisonto nge-intshi nganye (tpi)
ß = i-engile yeprofayili
ϕ = i-engile ye-helix yomsonto
d = ubukhulu obukhulu bomsonto wangaphandle
D = ubukhulu obukhulu bomsonto wangaphakathi
d1 = i-diameter encinci yomsonto wangaphandle
D1 = Idayamitha encinci yentambo yangaphakathi
d2 = i-pitch diameter yomsonto wangaphandle
I-D2 = i-diameter ye-thread pitch yangaphakathi
I-pitch diameter, d2/D2
Idayamitha esebenzayo yomsonto. Malunga nesiqingatha phakathi kwedayamitha ezinkulu nezincinci.
Ijometri yomsonto isekelwe kwidayamitha yepitch yentambo (d, D) kunye nepitch (P): umgama we-axial ecaleni komsonto kwi-workpiece ukusuka kwindawo enye kwiprofayili ukuya kwinqanaba elilandelayo elihambelanayo. Oku kunokubonwa njengonxantathu odlula i-workpiece.
vc = isantya sokusika (m/min)
ap = ubunzulu bomsonto bubonke (mm)
nap = ubunzulu bomsonto bubonke (mm)
tpi = imisonto nge-intshi nganye
Ukutya = inowuthi
