5 Ways Computers Changed Car Making Forever

The CNC Revolution

How Did Computers Bring a Revolution in Vehicle Parts Manufacturing?

Earlier, making 1 small part took 1 full day.  

After Computers + CNC came, the same work now takes 10 minutes.

Here are the 5 Major Revolutions computers brought:

1. CAD Design - The Drawing Revolution

Before: 1 drawing on a drafting board took 1 whole day.  

After: AutoCAD, SolidWorks makes a 3D model in 30 minutes. Mistakes are caught instantly.

2. CNC Machine - The Manufacturing Revolution

Before: A worker turned levers by hand. 5-10 defects in every 100 parts.  

After: Just feed the program to CNC Lathe, CNC Milling. Accuracy up to 0.005mm. Runs 24/7.

3. CAM + Robotics - The Speed Revolution

The computer directly commands the CNC machine. Human error = 0.  

Robotic arms load the part, `CNC` cuts it, `CMM Machine` checks it.

4. Quality Control - The Accuracy Revolution

Before: Every single part was checked manually with a Vernier Caliper.  

After: `CMM + Laser Scanner` catches even a 0.001mm difference.

5. Mass Customization - The New Thinking Revolution

Before: New part = make a new jig. That took 15 days.  

After: Just change the program in the computer. Today one company's vehicles parts, Tomorrow another company's vehicles parts.

Before vs After Computer

Work Without Computer With Computer + CNC

Accuracy 0.1mm 0.005mm

Defect Rate 5% 0.1%

New Model Launch 4 Years 18 Months

Conclusion

A computer didn’t replace the craftsman. It gave the craftsman "superpowers".  

Today, 1 operator can run 10 CNC machines that used to take 10 workers before.  

That’s why cars today are cheaper, faster to build, and better in quality.
