Introduction
Computer Numerical Control (CNC) is a manufacturing process where pre-programmed software controls the movement of machinery. The technique, frequently used in the metalworking industry, significantly simplifies complex processes such as drilling, grinding, punching, and more. One exceptional functionality enabled by CNC is turning, which we will explore in detail alongside understanding different types of rivets.
Understanding CNC Turning
CNC turning involves spinning a workpiece on a rotating axis while performing numerous cutting operations with various tools. The process carves away excess material to create a symmetrical object around an axis.
The specialty about CNC turning lies in its precision. It produces complex shapes that would otherwise be impossible or too costly to manufacture manually. Despite its complex nature, this is achieved through automated control without needing complicated manual adjustments—a remarkable advantages over traditional lathes.
Producing high-quality products using CNC Turning begins with creating a detailed 2D or 3D CAD drawing, the first step in establishing the controllers’ path and movements throughout the production cycle. Once these coordinates are sent to the machine, the operator locks the piece into place for the machine to begin shaping it according to the set instructions.
Types of Rivets in CNC Machining
Just as crucial as machining techniques like CNC turning in industrial manufacturing are fastening methods. Of course, here the ubiquitous small yet mighty performer in holding materials together tightly comes to mind – rivets. Given their widespread usage, there exists several types of rivets catering to different applications in CNC machining:
1. Solid Rivets: These are the oldest type of rivets simply consisting of a shaft and head. They’re commonly used in aircrafts spaces due to their unmatched strength properties.
2. Semi-Tubular Rivets: As the name suggests, these rivets feature a partial hole at the end opposite to the head. Their design allows for less force during assembly, making them suitable in delicate workpieces.
3. Blind Rivets: Also known as “pop-rivets,” these are employed when access to the project is limited to one side. Once inserted into a pre-drilled hole, a blind rivet gun pulls on a stem at the center, causing it to deform and hold the two pieces together.
4. Drive Rivets: These have a domed or countersunk head and a short cylindrical body ending with a tapering hole that receives a nail-like mandrel. They’re often used where tightness of fastening isn’t critical, like number plates fixing.
5. Flush Rivets: Widely used in aeroplanes and industrial appliances for their high strength and smooth finish, flush rivets sit almost level with the material once installed.
Producing Rivets using CNC Techniques
Rivets can be mass-produced employing various methods, including cold heading and CNC machining. In CNC production, the selected metal rod is locked onto a spinning chuck on the CNC lathe. Precision tools then shape the rod’s end into the desired rivet head. The machined piece is cut off, ready for use or any additional necessary finishing procedures such as thread rolling if producing threaded rivets.
Conclusion
The world of manufacturing entails remarkable processes and essential elements that make our daily lives easier. Techniques like CNC turning offer impressive accuracy while working with diverse materials. Similarly, seemingly small elements like different types of rivets play crucial roles in holding together massive structures securely. By understanding these aspects in depth, we unravel the magic behind numerous everyday functionalities.
Whether you’re new to CNC machinery or looking to expand your knowledge, acknowledging both broad aspects like CNC Turning and minute details like rivet types can empower you to exploit fully all major techniques that this innovative technology offers.
