Machining is the general term for using specific types of equipment and tools to remove material from a workpiece to create the desired shape. There are several different processes that fall under the general umbrella of machining. All of these services are available using manually operated equipment or the use of CNC machines.
CNC milling services use CNC or computer numerical control on the equipment. This starts with a specific plan, known as a drawing or model, that is designed in a CAD/CAM software system. The software then develops a very specific set of commands that will be sent to the CNC milling machine to precisely control all aspects of the milling process.
Control of All Tools
One of the major advantages of using CNC milling services is the ability of the software to precisely control the movement of multiple tools used for cutting, drilling or for finishing processes. The process is set up through the system to optimize efficiency, creating a smooth and seamless flow through of the workpiece in the equipment.
Not only does this cut down on unnecessary aspects of the milling process, but it can also speed up production, allowing for more parts per time period produced. As there will be no waste due to human error, these combine to create a cost saving that increases with the volume of production.
Cost Comparisons
While there is some initial cost in developing the CAD/CAM drawing and setting up the software program, this is a relatively small price with large volume orders. Even with a prototype, developing the CAD/CAM drawing will typically be required to move into large scale production and, once developed, the program simply sits in a file that can be accessed and used with each production run, creating parts that are not just identical to each other but identical to the master prototype design.
