Aaj kal free 3D models online dhoondhna buhat aasan hai. Chahay woh GrabCAD ho ya Thingiverse, engineers aur designers aksar fori (quick) solution ke liye in models ka istemal karte hain. Lekin, kya yeh designs manufacturing ke liye tayyar hain? Humari CADI PRO team ne jab aise 5 aam (common) designs ka professional tajziya (analysis) kiya, to humein 7 aam Design for Manufacturability (DFM) errors nazar aaye.
Yeh errors na sirf production cost badhate hain, balke product ki performance ko bhi kam kar sakte hain. Is article mein hum un 3 sab se zaroori ghaltiyon par gehri roshni daalte hain jo aapke design ko bhi nuksan pahuncha sakti hain.
1. Design for Manufacturability (DFM) Kya Hai?
DFM ka matlab hai ke aapka design sirf khoobsurat na ho, balke usay kam waqt aur kam mushkil se factory mein banaya ja sake. Jab koi design DFM standards par poora nahi utarta, to woh ya to buhat mehnga banta hai, ya phir fail ho jata hai.
2. Woh 3 Critical Errors Jo Humne Dekhe:
Error A: Zaroorat Se Zyada Tight Tolerances (Over-Tolerancing)
Masla: Designers aksar har feature (jaisay holes ya slots) par buhat hi chote tolerances (jaisay ±0.001mm) laga dete hain, yeh soche baghair ke machine yeh precision de payegi ya nahi.
Nuksan: Manufacturing cost 5 guna (times) tak badh jati hai! Agar aapko 0.1mm ki tolerance chahiye, to zaroorat se zyada tight tolerance dena sirf paisa zaya karna hai.
CADI Pro Hal: Hum Tolerance Stacking Analysis karte hain taake aapka design sirf wahan tight tolerance istemal kare jahan woh functional taur par zaroori ho.
Error B: Sahi Material Ka Khayal Na Rakhna (Material Mismatch)
Masla: Online 3D model sirf geometry (shakal) dikhate hain. Woh yeh nahi batate ke kya yeh part asal mein aluminum 6061 se banna chahiye ya stainless steel 304 se.
Nuksan: Agar part ghalti se galat material se ban jaye to woh load nahi utha payega aur toot jayega (Fail ho jayega). Misaal ke taur par, agar aapne FEA analysis theek nahi ki to aap galat material chunenge.
CADI Pro Hal: Hum aapki design ke maqsad (purpose) ke mutabiq sahi Material Grade ki specification aur FEA (Stress Analysis) ki tafseel (details) dete hain, taake product har haal mein perform kare.
Error C: Assembly Ya Attachment Ki Ghalti (Fastener Flaws)
Masla: Zyadatar free models mein yeh nahi bataya jata ke unhein asliyat mein kasna (assemble) kaisay hai. Parts ke beech mein zaroori chamfers ya fillets nahi hote jo assembly ko aasan banaein.
Nuksan: Site par workers ko part ko fit karne ke liye zor lagana padta hai, jis se part ya to kharab ho jata hai ya uski lifetime kam ho jati hai.
CADI Pro Hal: Hum DFM review mein assembly ke raste (path) aur fastener access ko theek karte hain taake aapka design sirf design na ho, balke assemble-ready ho.
3. CADI Pro Aapke Designs Ko Kaisay Bachayega
Free models sirf shuruaati (initial) ideas ke liye achay hain, lekin manufacturing se pehle professional verification zaroori hai. Humari services aapke design ki performance aur cost ko yaqeeni banati hain:
- Hum aapke complex designs mein Tolerance Stacking aur Interference check karte hain.
- Hum aapke product ke liye sab se sasta aur mazboot material chunte hain.
- Hum aapko final, code-compliant 2D engineering drawings tayyar karke dete hain.
Agar aapka design in 7 aam ghaltiyon se azaad ho, to aap humari CADI PRO services check kar sakte hain.
Humari policies ke baray mein mazeed maloomat ke liye, humari Privacy Policy par bhi nazar daalein.
