Computer numerical control (CNC) technology is revolutionizing modern manufacturing, encompassing various techniques – one of them being CNC turning. On another note, riveting is an age-old technology that has experienced innovation over the years, spawning diverse types of fasteners in the process. This article will delve into the fascinating world of CNC turning and explore different types of rivets, their applications, and production methods.
CNC Turning: Defined
CNC turning is a manufacturing process whereby computer software runs the operations of lathes or turning machines. The highlight of this method involves removing material from rotating workpieces using cutting tools strategically positioned at differing angles. An advantage includes its ability to ensure precise machining for components requiring tight tolerances while serving both low-volume and high-production manufacturing requisites.
Producing Complex Products with CNC Turning
To use CNC turning in producing any product, we follow several steps. First is the design phase where engineers draft blueprints of the intended part using Computer-Aided Design (CAD) software. Once completed, the design is converted into a readable coded programming language, often G-code, via Computer-Aided Manufacturing (CAM) programs.
Next, the specifications are inputted into the CNC machine; it’s calibrated to conform with the required parameters ensuring dimensional accuracy. The chosen raw material – which can be metal, plastic, wood etc., is mounted on the chuck connected to the spindle within the lathe. As the chuck rotates, the automated cutting tool executes the programmed instructions by shaving material off the spinning workpiece until the desired shape is achieved. Post-production processes may include deburring, polishing, and quality checks.
Diving Into Types Of Rivets
Plunging into our next keyword, let’s understand rivets better. At heart, a rivet is a permanent mechanical fastener consisting of a smooth cylindrical shaft with a head on one end. They are installed by drilling them into pre-cut holes in the materials to be joined whereupon the plain-end is deformed either by hammering or through use of a rivet gun, thus forming another head and securing the join.
Rivets come in various types depending on particular applications;
1. Solid Rivets: Also known as round head rivets, they are some of the oldest and most reliable rivet types. From aircraft construction to high load-bearing structures, these often steel or aluminium based fasteners are very much prevalent.
2. Pop or Blind Rivets: These are tubular and intended for one-sided access applications. Use of specialised tools expands their tail end once installed, creating a secure clamp between surfaces.
3. Semi-Tubular Rivets: Similar to solid rivets but with hollow ends that reduce setting force requirements. They find grounds in automobiles, brake linings and appliances.
4. Drive Rivets: Simple set up with just a hammer required. The particular feature is the drive pin inserted into the rivet shaft which, when hit, flares out the shaft for installation – ideal for soft materials.
5. Flush Rivets: Low profile variant designed to sit flush against material surface. Prominent within aeroplane and automotive industries owing to streamlining capabilities reducing drag and optimizing fuel efficiency.
Creating rivets adheres to many manufacturing processes including cutting, machining, heat treatment, et al. Materials initially sourced undergo dimensioning according to product specification. Upon quality checks, they advance towards conversion into flat circular discs through punching presses. Subsequent operations transform these blanked components into impression-die forging machines, venturing in stages from extrusion to upsetting until the final formation inclusive of head and shank portions achieved post cooling.
CNC turning and differing types of rivets both invite intrigue given their diverse application prospects and capability of producing precision-centric solutions. Understanding their nuances opens the door to exploring varying avenues of product and technological design – building cues for better craftsmanship in manufacturing units globally.
