Machining Process and Different Tools
Often, machining processes require the use of multiple tools to achieve the desired cuts (e.g., drill bits of different sizes). CNC machines typically group tools into common units or cells that the machine can access. The vast majority of today's CNC arsenals are entirely electronic. Some of the more common operations used in CNC include ultrasonic welding, drilling, and laser cutting.
CNC Machine Systems
- CNC mills can operate on programs consisting of number and letter-based commands that direct parts along various distances.
- On lathes, parts are cut in a circular direction with interchangeable tools.
- With CNC technology, cuts used on lathes are performed precisely and at high speed.
- Plasma Cutters
- Electrical Discharge Machines
- Water Jet Cutters
How Does a CNC Machine Work?
While basic machines move along one or two axes, advanced machines move laterally in the x, y axes, longitudinally in the z axis, and often rotate around one or more axes. Multi-axis machines allow you to machine material that was previously “underneath” by automatically flipping parts, which eliminates the need for workers to flip prototype stock material and allows you to cut all sides without manual intervention. Fully automated cuts are generally more accurate than what is possible with manual inputs. However, sometimes finishing work, such as engraving, is better done by hand, along with simple cuts that require extensive design work to program the machine for automation.
