Examples
- A good example of cad and cam is in the food market where they need to design complicated nets and put a design on it and then cam can cut out thousands and even millions of copy’s
- Also something like digital cameras they can mass-produce all the little parts in it, and using cad will make sure they will all fit together perfectly.
- Also designing something for resistant materials. It takes much less time and produces a perfect piece of work.
Before cad cam
Before there was cad cam people just use to use ordinary tools like pens, pencils and paper etc. this would take a lot of time and effort and would even cost more in the long run .If you ever made a mistake you would have to use a rubber to rub it out or even start again Well before the development of Computer-aided Design the manufacturing world adopted tools controlled by numbers and letters to fill the need for manufacturing complex shapes in an accurate and repeatable manner. During the 1950's these Numerically Controlled machines used the existing technology of paper tapes with regularly spaced holes punched in them to feed numbers into controller machines that were wired to the motors positioning the work on machine tools. The electro-mechanical nature of the controllers allowed digital technologies to be easily incorporated as they were developed.
. But now with cad cam if you make a mistake you can just delete it strait away and things are so much quicker and easier once you get used to it. Also it is so much more accurate because you can type in the exact angle etc. Also they didn’t have cam so they would have to make their projects by hand.
Using cad cam in resistant materials
When you do resistant materials it quite hard to make precise pieces of work to how you drew them but when you use cad/cam it is much easier
How it is done
- design the piece you would like to make on the computer this is using cad. One of the programs used is 2d design this is a screen shot from someone designing a net on it.
- Then you first have to have to connect the computer to a cam machine and then you have to configure it e.g. position the output accurately, control depths of cut, feeds, speeds, etc., as shown below
- Then you let the machine do the work and hopefully it will produce the product you designed here are a few finished products that have been done using 2d design
TYPICAL WORK PRODUCED USING 2D DESIGN
Having the use of cad cam in resistant materials has helped the mass-producing of products a lot as before this would be hard to do. You would have to do each piece by hand which wouldn’t be as accurate and would be much more time consuming. Also if you aren’t very good at doing resistant materials using tools etc. then cad cam would be a lot easier because all you need to be good at is computers and designing. Now people can mass produce products without employing as many staff and it would also take less time therefore produce more money in the long run
Conclusion
Overall you can see that cad cam is so much better than old-fashioned ways because it is
- Faster
- More convenient
- Easier
- Easy to correct mistakes
- Mass production.
Cad cam has influenced our world so much more because it stops mistakes and creates everything the same so there are no mistakes in any of the things made.
It has influenced the electronically world a lot because they like to mass produce things a lot as well with packaging etc. so overall cad cam is better.
