What Factors Decide Your Mini CNC Router Working Time?

We have received so many consultation about the mini cnc router machine engraving time.
For example,
How long our CNC 6040 can work?
How long our CNC 3040 can work?
How long our CNC 6090 can work?
How long our China 5 axis cnc router machine can work?

In fact, the engraving time is decided by many factors. 
Under the correct cutter choosing and parameters setting, a workpiece’s engraving time is decided by below factors, 

1) The size and complex standard of workpiece 
2) Configuration of machine 
3) Engraving materials 
4) The skill level of user 

Factually, there is some similarities between engraving process and car driving. 
1) The size and complex standard of workpiece 
The time of a car travel 50 km is different with travel 100 km, travel forthright way is different with tortuous way, similarly, the time of engraving a small piece is different with engraving a large piece, the complex standard of pattern also a factor. 

2) Configuration of machine 
Compared the displacement 2.0 car with 4.0 car, their speed must be different, so it can be easily understand that the speed difference between 240W machine and 2200W machine. 

3) Engraving materials 
We all know that the speed when car drive in high speed way is faster than drive in mountain road, similarly, the speed engraving aluminum is slower than acrylic. 

4) The skill level of user 
We know even same car, same road, but driver’s skill is various, so the driving time is also different. Same hobby cnc milling machine, even same pattern image, but user’s skill standard in G-code design and parameters setting also a important elements. 

In conclusion, the exact engraving time can be pre-judged easily.
