What Parts Can CNC Turning Make?

How did people perform the shaping of materials before the advent of precision engineering? Human operators had to work hard manually to shape materials such as metal and plastics. Because of imprecise measurements and lower quality, many errors used to occur those days. Today, components can be manufactured according to the exact specifications with meticulous precision. Thanks to the advancements in computer technology. It is hard to find a better method in the precision engineering industry than Computer Numerical Control (CNC) Turning. There is an increasing demand for CNC turning parts nowadays.

What Is CNC Turning?

As mentioned above, CNC refers to Computer Numerical Control. CNC turning is a subtractive machining process that utilizes a cutting device to remove material for making cylindrical components. When the part rotates, the tool moves along the machined part’s axis to create a helical tool path.

Computerized systems control the machinery when it comes to turning parts on a CNC mill. A digital code works as the input. All actions, including tool movements, spinning speed, and coolant functioning, are controlled by a computerized system.

Four steps involved with the CNC turning process

Let us discuss a bit more about the CNC turning process. There is nothing complicated about the cutting process. What are the steps to be followed when it comes to making CNC turning parts?

First step

The process starts with the task of creating a CAD file. That is to say, you need to make a digital representation of the component or part in CAD. It can be done in two different ways. You can utilize a CAD program to create files before sending them into production.

The second option available is to utilize CAD-CAM software which allows the design engineer to check the producibility of the part. The entire process can be visualized with the help of advanced simulation tools.

Second step

The next step is to create the machining code from the CAD files. The manufacturing engineer creates the G code and the M code.

Third Step

Now, you have to set up the CNC lathe. The machine operator has a role to play during this phase. The CNC lathes almost perform most of the work automatically. However, the intervention of the operator is also needed here.

CNC machining can invite serious danger. The operator has to ensure that the power switch is off. The component is held by the chuck during the whole process. So, securing the part into the chuck is a task that deserves maximum vigilance. Improper loading may invite unwanted danger. It may also create a finished component with incorrect dimensions.

CNC turning involves many tasks. The operator must select the most suitable tool for a specific finish. That is to say, loading the tool turret is a very task. Calibration is another task that the operator should be careful about. Any mistake will not fulfill the exact demands. The last thing the operator should pay attention to is uploading the code into the machine.

CNC turning uses many different types of lathes. Each one comes with its own advantages. You can find them highly suitable for various projects. The most common lathes you can come across in precision engineering workshops are horizontal CNC lathes, vertical CNC lathes, horizontal turning centers, and vertical turning centers.

Horizontal CNC lathes hold the part from the side. They are one of the most commonly used machines in CNC turning. Vertical CNC lathes get hold of the workpiece from the bottom and turn it in circles rapidly while staying in one spot.

What about Horizontal turning centers? They are known as enclosed CNC lathes that come with integrated milling and drilling capabilities. These lathes are also capable of including things such as coolant flooding and conveyor belts. Vertical turning centers are a perfect blend of a CNC mill and a horizontal turning center.

Fourth Step

Finally, you can perform the manufacturing of the turned parts or components. A hexagonal profile is the most efficient way to get the best results. You may need one or more cycles based on the complexity of the part. The total time taken is determined by cycle time calculations. Four factors constitute a turning cycle time, loading time, cutting time, idle time, and tool lifetime.

What CNC Turning Parts can be Made?

CNC Turning can be termed as a highly versatile manufacturing process. It has been extensively used in the engineering, aerospace, and automotive industries nowadays. However, this manufacturing process is also utilized to create objects such as ornaments and pieces of art.
