> Qual è la definizione di lavorazione CNC?

> Quali sono le precauzioni per il design dello spessore delle pareti?

fril> 1. lo spessore della parete è uniforme per evitare la deformazione

Nella lavorazione del mulino, lo spessore della parete irregolare può portare a concentrazione di stress e deformazione o cracking dopo il macinazione. Durante il processo di progettazione, dovrebbero essere compiuti sforzi per mantenere lo spessore del muro coerente o per aggiungere strutture di supporto ove necessario.

2. L'impostazione del parete minima ha bisogno di abbinare l'incontro con l'accompagnamento di elaborazione per corrispondere all'elaborazione di elabora Capacità

• La lavorazione del tornio richiede un grado concentrico elevato per parti a parete sottile. Si consiglia generalmente lo spessore della parete minimo ≥0,5 mm.
• La macinatura La macinatura è influenzata dall'abrasione della ruota, la parete sottile è facile da deformarsi, dovrebbe essere riservato un divario di almeno 0,3 mm.

3.sorndi i tendini e ottimizza gli angoli di transizione

• > Aggiungere il rinforzo alla lavorazione del mulino può migliorare la rigidità locale, ma è necessario evitare il sovradimensionamento, in modo da non rendere difficile rimuovere i chip.
• Aggiungi r = 0,5 mm o più angoli arrotondati sulle pareti interne ed esterne per ridurre la concentrazione di sollecitazione utensile durante la macinatura.

4. Caratteristiche del materiale e adattamento della tecnologia nell'elaborazione

materiali ad alta resistenza, come leghe di titanio, il malato più spesso per accomodare

Complex wall Le strutture di spessore richiedono ottimizzazione della macinazione Machining percorso dello strumento Per evitare la frequente sostituzione degli strumenti. il taglio elicoidale può essere usato per ridurre lo strumento nella struttura della cavie.

fril> 7. Cambiamenti di dimensione dopo il trattamento della superficie

Qual è l'impatto della complessità geometrica su CNC?

La complessità geometrica ha un grande impatto sulla lavorazione a CNC, in particolare nella macinatura della macinatura e della lavorazione del tornio. Le seguenti differenze e sfide devono essere enfatizzate:

1. Pianificazione del percorso dello strumento ed efficienza di lavorazione

• Milling machining : superfici complesse o strutture irregolari richiedono un processo di elaborazione multi-assi. ottenuto utilizzando macchine utensili a tre assi.
• 2. Selezione dello strumento e controllo dell'usura
  • Milling La rotazione della rotazione: i contorni complessi (come thread e alberi a camme) richiedono strumenti di modellatura o più canali, mentre le parti dell'asse di luce richiedono solo utensili da taglio standard, quindi gli strumenti durano più a lungo.

  frileg> 3. Accuratezza di elaborazione e qualità della superficie

  • Milling machining: Steep sidewalls or suspension structures that vibration patterns easily richiedono l'ottimizzazione dei parametri di taglio o la fresatura ad alta velocità , le superfici piatte o regolari rendono più semplice l'accuratezza.
  • 4. Costi di elaborazione e fattibilità
    • Milling machining : le parti complesse richiedono macchine utensili altamente accurate e programmatori esperti, aumentando notevolmente i costi, le strutture semplici possono ridurre i costi attraverso processi standardizzati.
    • 5. Rimpassuramento e controllo di qualità
      • Milling MACCHINING : le forme complesse possono avere baratteri residui o segni di lavorazione e richiedere ulteriori lucidatura o trattamento elettrochimico.  Machining di svolta: il threading di precisione o le superfici di accoppiamento richiedono strumenti di misurazione specializzati per l'ispezione, mentre i cerchi esterni convenzionali possono essere ispezionati rapidamente con gli arresti.

      Modellazione CAD tradizionale vs. Design AI generativo: gli algoritmi possono sostituire l'esperienza dell'ingegnere?

      In the traditional CAD modeling and generating AI design comparison, algorithms cannot completely replace the experience of engineers, especially in the field of machining CNC, i due devono integrarsi a vicenda. The following will be analysed in terms of technology, applications and industry Pratiche:

      1. > Confronto delle competenze chiave

      dimensione	Modellazione CAD tradizionale	Design AI generativo	JS Company Practice
      logica di design	Modello di ingegneri a mano secondo le leggi della fisica ed esperienza.

      2. Limitations of Generative AI

      • Lack of machining experience: CNC machining involves practical experiences such as tool path planning and setting of cutting parameters. Models generated by AI may ignore the feasibility of machining (such as tool interference and stress concentration) and require calibration by engineers.
      • Material property adaptation: JS company processes more than 50 materials (metals, composites, etc.), each with processing characteristics that make it difficult for AI to fully grasp the impact of material microstructure on shaping, relying only on material selection recommendations from engineers.
      • Quality control boundaries: In the JS case, for example, 98% of orders were delivered on time, relying on engineers to adjust processing errors in real time. Currently, AI cannot dynamically respond to variables such as machine tool state, ambient temperature and humidity.

      3.The manifestation of collaborative value

      Step by Step	The role of AI	The role of engineers	JS case results
      Conceptual design	Generate multiple solutions to shorten the cycle (e.g. JS reduces design time by 15%).	Choose a solution that meets the processing logic.	Client projects were completed an average of 15% ahead of schedule.
      Optimization	The combination of cutting parameters is recommended.	Adjust parameters according to machine performance and material characteristics.	Precision ±0.005mm (95% JS compliance rate).

      Innovation breakthrough	Explore the possibilities of non-traditional structures.	Evaluate the feasibility of mass production and improve the design.	Develop multiple patented precision components.

      Algorithms are tools, experience is irreplaceable

      The practical logic of JS: Using generative AI for initial design exploration (such as quickly generating multi version shell structures), followed by engineers screening and optimizing based on CNC process constraints (such as JS's ±0.005mm tolerance), material properties (such as titanium alloy processing temperature), and customer case experience (such as batch consistency of automotive molds).

      Generative AI can improve design efficiency, but the core of machining CNC experience and quality control-still needs to be led by senior engineers. The success of JS demonstrates that the human-machine collaboration model (AI assisted+manual verification) is the most optimal solution for current manufacturing.
