Drawing se finished part tak ka complete journey—CAD → CAM → Post Processor → G-Code → CNC Machine. Har step samajhna important hai!

CNC Machine, Fusion 360, PowerMill ya kisi bhi CAM Software ke saath kaam karte ho to G-code ka naam zarur suna hoga. Lekin ek common question hota hai:

“CNC Machine G-code ko kaise samajhti hai?” — Is guide mein drawing se lekar machine movement tak ka complete process simple Hinglish mein samjhenge!

📋 Drawing Se Part Tak — 5 Steps

1

CAD Model Banta Hai — Design Stage

Autodesk Fusion / SolidWorks / Inventor / Creo

Engineer CAD software mein part design karta hai — sirf geometry hoti hai, machine kuch bhi nahi samajhti ab tak:

Autodesk Fusion
Inventor ⭐
SolidWorks
Creo
Output: STEP/IGES ⭐

2

CAM Software Toolpath Banata Hai

Fusion Manufacturing / PowerMill / FeatureCAM

CAM software decide karta hai — lekin machine abhi bhi nahi samjhti, ye internal data hai:

CAM toolpath — tool movement, strategy, feeds sab calculate hota hai lekin machine-language nahi hota ab tak.
Tool selection
Spindle speed
Feed rate
Step over/down
Toolpath direction
3/4/5-axis path

Post Processor — Sabse Important Step! ⭐

CAM Toolpath → Machine-Specific G-Code

Critical!

Post Processor CAM toolpath ko convert karta hai machine-specific NC Program (G-Code) mein:

G-Code Machine Mein Load Hota Hai

USB / Network / DNC se transfer

Generated NC program machine mein load hota hai — machine line-by-line read karti hai:

/* CNC Machine — Line by Line Execute Karti Hai */

G90 /* Absolute Mode */
G54 /* Work Offset */
T1 M06 /* Tool Change */
S8000 M03 /* Spindle ON */
G00 X0 Y0 /* Rapid Move */
G43 H01 Z100 /* Tool Length */
G01 Z-20 F500 /* Cut Down */
M30 /* Program End */

Machine ek line execute karti hai → phir next → phir next. Bilkul waise hi jaise computer ek-ek instruction execute karta hai!

✅ CNC Machine Part Manufacture Karti Hai!

G-code ke hisaab se axes move, spindle rotate, tool cut

G-code run ho raha hai — X, Y, Z, A, B, C axes move kar rahe hain, spindle cut kar rahi hai, finished part ban raha hai!

💻 Common G-Code Commands — Kya Karte Hain?

Command Kya Karta Hai Example
G00 Rapid Movement Tool ko fast position par le jao
G01 Linear Cutting Straight line mein cut karo
G02 Clockwise Arc Round corner clockwise
G03 Counter-CW Arc Round corner counter-clockwise
M03 Spindle ON ⭐ Spindle start karo + speed set
M06 Tool Change Alag tool lagao
M08 Coolant ON Cutting fluid start
M30 Program End ⭐ Program finish, machine stop

Tool library + post processor combined = correct tool numbers, speeds, feeds automatically NC code mein aate hain. No manual entry!

⚠️ CNC Machine Sochti Nahi Hai — Ye Sabse Important Point!

CNC Machine

Sirf wahi kati hai jo G-code mein likha hai — koi decision nahi leti!

❌ G-code galat = Machine galat chalegi

❌ Wrong feed = Tool break ya scrap

❌ Wrong axis direction = Collision!

✅ Proven post = Always correct G-code

Isi liye Programming Accurate Honi Chahiye + Proven Post Processor Essential Hai! ✅
