This holds true for businessmen who are contented with being small-time (though it's hard to find one). However, for businesses that are aggressive towards getting ahead, acquiring a CNC machine seems to top their list of priorities.
CNC stands for Computer Numerical Control. A CNC machine is a computer "director" which is composed of machine tools that read a specific set of instructions (in G-code) and is able to direct certain manufacturing tasks repetitively. The top industries that use the CNC technology are the Metal and Woodworking industries.
If you are a regular member of a techie forum for entrepreneurs, CNC may be showered with praises because of its performance. Most businessmen also swear by saving a lot of money and time when they started employing CNC technology in their production processes. However, if you are still considering CNC at the expense of the jobs of your employees, it is best that you prefer CNC at two levels: the logical level and the emotional level.
CNC machines do specific instructions. They will never assume anything, nor rebel against the program loaded to them. Imagine the security of knowing that you will "reap" exactly what you "sowed". Let's say, something goes wrong during the process. Assuming the machine is in perfect condition, you CANNOT put the blame on it because it just performed what you told it to do so.
Secondly, there is the blanket of consistency. It provides a certain level of safety and ease to the head supervisor. If you have overseen the operations today, most likely, it will be exactly the same tomorrow. The feeling of knowing what to expect is always a good thing, especially when there's money involved.
Lastly, there's speed. CNC machines do not stop to think. After you do the thinking, they do the power-jobs that they need to do. Its that simple. There is a minimized set-up time and back-job time pocket.
What you will find a flaw about CNC though, is that logic-wise, CNC machines cannot think of better ways to perform a task (IF there is a better way). A CNC machine is purely mechanical; when it was sold to you; the salesmen never mentioned the word creative or "innovative". I hope you did not miss that.
CNC machines are also assets of the company. When assets like this are purchased, there is little or no emotional investment that goes with it. You won't even train it! It is expected to do certain tasks and thats saving you a lot of time from all the explaining, demonstration and reminding.
Also, when a CNC machine is performing its task, it is void of any emotion. So no matter how hot the weather is, or how noisy the workplace is, the CNC machine will do its job just like any other day. It is different as compared to people - who have the tendency to space-out when doing very mechanical and tedious jobs.
Although the CNC may want to, it also cannot complain. That's really convenient. What you will need to note now is your electric bill. Beware, for when getting CNC machines, it may betray you in the form of lofty bills. All the emotions youve saved might just be unleashed.
