CNC machining is a popular manufacturing process used in different industries such as aerospace, automotive, medical, and many more. Among the various processes involved in CNC machinery, one that stands out for its versatility is CNC turning.
In essence, Computer Numerical Control (CNC) turning is a subtractive machining process in which a cutting tool moves in a linear fashion while the workpiece rotates. This motion cuts away material to create cylindrical parts with precise measurements. With this technology’s help, we can produce sophisticated components seamlessly and economically, significantly reducing manual labor and errors.
The CNC turning procedure starts by designing the part using CAD (Computer-Aided Design) software. After finalizing the design, it’s converted into a computer numerical program or G-code, guiding the machine throughout the production process. Then, the appropriate piece of metal, wood, or plastic is loaded into the CNC turning center. Once the machine starts, the raw material turns at high speed while the cutting tool follows instructions from the inputted code, precisely sculpting the workpiece into the desired shape.
It is worth noting that there are various types of CNC turning based on the operational functionality and complexity of the produced piece, including standard turning, hard turning, facing, grooving, threading, etc. Each type has specific advantages tailored for individual production needs.
While speaking of manufacturing components and assembly operations, another integral element is riveting. Like CNC turning, understanding the different kinds of rivets is key to choosing the appropriate fastener for your project.
Rivets are permanent mechanical fasteners consisting of a head on one end, a tail on the other, and a smooth cylindrical shaft connecting both ends. To use them, the tail is placed through a hole in two separate materials and is then deformed so it expands, creating a second head, locking down and permanently joining the pieces together.
Different types of rivets are available in the market, each serving a particular purpose:
1. Solid Rivets: These are the oldest type of rivets and are known for their robustness. Once set, they create a permanent bond that can withstand high loads.
2. Pop or Blind Rivets: They need access to only one side of the assembly making them ideal for closed structures like tubing or cases.
3. Semi-tubular Rivets: These have a hole at the end of the stem and require less force to install than solid rivets.
4. Tubular Rivets: Similar to semi-tubular but distinguished by hollow bodies that reduce weight with almost equal strength as solid rivets.
5. Drive Rivets: With a short mandrel extending from the head, these are applied using a hammer so the mandrel expands the end, creating a firm join.
6. Flush Rivets: Used where smooth surface requirements exist, like on aircraft exteriors, they deliver high shear strength despite being very low-profiled.
CNC turning and the use of rivets are both integral processes in manufacturing and assembly operations across different sectors. Understanding these tools’ working principles allows for architects, engineers, and manufacturers who tap into this knowledge to choose wisely and achieve excellent results. Through advanced innovations such as CNC machining, industries continue to improve production quality and efficiency, contributing to technological progress forward.
