Common ways to eliminate internal stress are to use natural or artificial aging and vibration treatment。In secondo luogo, Pre-machining of workpieces excess material, Natural aging for 1-2 hours before processing and shaping, It can also eliminate deformation caused by internal stress.
Milling of thin-walled aluminum parts with poor rigidity, The following clamping methods can be used to improve processing accuracy: Use vacuum suction cups to clamp workpieces for evenly distributed clamping force; Use the method of filling media inside the workpiece to improve the rigidity of the workpiece.
Knife material, Geometric parameters, Tool structure has an important influence on cutting performance, Correct choice of tools, Essential for improving dimensional stability in processing.
The CNC high-speed cutting process is generally: Lavorazione grezza – semifinitura – corner cleaning – finishing and other processes. Per parti con requisiti di alta precisione, Need to increase the number of semi-finishing operations, and retain a uniform machining allowance.
Choose the right feed rate, Spindle speed and depth of cut;
Use symmetrical processing method for the front and back sides of the workpiece, Avoid centralized processing which is not conducive to heat dissipation.
Evita pareti sottili
Uguale alle caratteristiche alte, Le vibrazioni aumentano quando si lavorano sottili. come guida, Lo spessore minimo delle parti di metallo a parete sottile è 0,5-0,8 mm, Lo spessore minimo delle parti di plastica è 1,0-1,5 mm. Se il muro viene utilizzato per il supporto o per le caratteristiche più elevate, Lo spessore della parete dovrebbe essere aumentato, Per evitare le vibrazioni durante l'elaborazione.
Evita il testo piccolo o rialzato
Potrebbe essere necessario contrassegnare la parte con il numero di parte o il nome dell'azienda, L'aggiunta di testo sembra bello, Ma l'elaborazione richiede molto tempo, L'incisione elettrochimica o l'incisione laser sono di solito migliori. Se devi macinare il testo, Scegli affondato piuttosto che un testo sollevato quando possibile, Mantienilo semplice con un testo più grande, La profondità del carattere non supera 0,3 mm.
Aderire agli standard di filo
Quando si crea thread, È anche importante attenersi alle dimensioni standard. Maggiore è il thread, Più facile è elaborare. La lunghezza dovrebbe essere mantenuta al massimo del diametro nominale del foro 3 volte. Per toccare il buco cieco, È meglio aggiungere almeno alla radice del buco 1/2 Lunghezza extra di apertura. Puoi anche prendere in considerazione l'uso di inserti, Bobine filettate e dadi di rame durano più a lungo dei fili lavorati nudi, Specialmente in materiali come l'alluminio o la plastica, e facile da installare.
L'angolo interno più grande possibile
Eventuali tagli interni creerà filetti, È metà del diametro dello strumento utilizzato. La fresatura con strumenti più piccoli richiede molto tempo, Raccomandiamo che il raggio sia maggiore della profondità di lavorazione 1/3. L'approccio migliore è eliminare gli angoli interni o consentire il più grande raggio d'angolo interno possibile nel design della parte di accoppiamento, e usa lo stesso raggio su tutti i bordi interni, in modo che lo stesso strumento possa essere utilizzato durante il processo.
Evita cavità troppo profonde、Scanalature e buchi profondi
La profondità della tasca e della scanalatura è generalmente correlata al diametro dello strumento utilizzato per macchina del filetto interno. Una buona regola empirica è mantenere la profondità tascabile uguale al diametro dell'utensile 3-4 volte, O la profondità della scanalatura è più piccola della larghezza della caratteristica 4 volte. Sia buco cieco o attraverso il buco, La profondità massima consigliata è diametro 4 volte, L'apertura minima è 1 mm, E si consiglia di progettare fori di dimensioni standard. Usa un bit di trapano standard, Può elaborare i buchi rapidamente e con alta precisione; Per buchi non standard, L'uso di End Mills aumenta i costi.
