Engineering covers a large cross-section of services that you might need. From industrial engineers to chemical or electrical engineering, there are so many different engineers out there. You can very likely find one to help you no matter what the project is that you are working on. When you need critical information interpreted and design or process changes made, an engineer should be the first stop.
One of the many things that an engineering service can cover is reviewing production processes to re-engineer the way the product is made. The idea is that they can evaluate the process you are using, crunch the numbers for you, and make recommendations about how to create a better workflow. In some cases, changing the process to make it work better might involve a completely new process.
If you have a product you are designing but need to make sure it is going to work at optimal performance, have an engineer look at the design and make recommendations. They can also create a CAD drawing for you or a CNC profile so that the part can be manufactured on a CNC machine. Sometimes a rough drawing is enough but other times you may have to spend some time with the engineer to explain what you are trying to make. This process can be long and tedious because you may have to test and revise over and over to get the part right.
While not every engineer specializes in it, reverse engineering can be helpful to determine why something works the way it does. This could be to mimic the function in another process or to try to troubleshoot a problem with the part or product itself. Often people think of reverse engineering as a way to steal someone else's work, but most of the time it is not used that way. There are cases where a company uses reverse engineering to copy a process, but most of the time it is simply a way to understand the function of something.
Some engineering service firms may also offer efficiency testing for your company. They will come in and look at your process to determine if there is anything happening in the company that is slowing production or creating a situation where something is holding up a process within the company. They will look not only at the manufacturing floor but also at the business units and the way your company works in general.
