What is CNC Machining?
CNC machine is commonly used in manufacturing and industrial production. But exactly what is CNC machining?
CNC (Computer Numerical Control) machining is a kind of subtractive manufacturing process. In CNC manufacturing, the software control system issues commands to make the tool meet the required movements. In this process,various precision tools are used to remove layers of raw materials and make parts or products. Therefore, it can also be called cnc precision machining.
Types of CNC Machining
Three-axis CNC machining
The 3-axis machining is performed by straight lines to the axes X, Y, and Z.
Machining features: the cutting tool orientation remains constant during movement along the entire cutting path.
The 3-axis machining center has the advantages of high precision and high efficiency. It is commonly used to machine general parts, but it is more troublesome when machining complex workpieces, which may cause the workpiece to fail. Therefore, multi-axis simultaneous machining is the first choice when machining more complex workpieces.
Three-axis CNC machining
Five-axis CNC machining
Five-axis machining is the use of CNC to move parts or cutting tools on five different axes simultaneously, which can process very complex parts.
The remarkable feature of the five-axis linkage CNC machine tool is that it can complete the surface machining, and no special fixture is needed during machining, which greatly reduces the number of clamping and improves the machining accuracy, quality and efficiency. The five-axis machining center has unparalleled advantages in the processing of complex workpieces.
Five-axis CNC machining
CNC milling
CNC milling machine processing is based on the technical requirements of the shape, accuracy, size and surface roughness of the workpiece to determine the processing technology and processing parameters. Program the machining program into the controller and send the command to the servo. CNC milling machines can process parts with particularly complex contours or difficult to control dimensions, such as mold parts and housing parts. It has the advantages of strong adaptability, high processing precision, stable processing quality and high efficiency.
CNC turning
CNC turning is one of the most used machining methods in CNC machining. During CNC turning, the workpiece makes a rotary motion, and the tool moves in a straight line or a curve. While the tool tip moves relative to the workpiece, a certain workpiece material is removed to form a corresponding workpiece surface.
Applications of CNC Machining
Electronic Products
The full metal casing of 3C products is basically processed by CNC machine tools CNC. CNC has become a must-have for 3C enclosure manufacturers due to its high efficiency, high precision and stable processing quality.
Automobile
CNC machining plays an important role in the automotive industry. It can be said that most automotive parts are processed by CNC machining.
The advantages of CNC machining in automobile manufacturing include multi-axis linkage to obtain the tortuous machining of prototype machining; high precision and good product consistency; high degree of automation, resulting in low labor intensity; CNC also ensures simplicity and high efficiency.

Applications: Metal casings, hardware, metal panels, environmental protection equipment parts, non-standard micro-miniature components, copper/aluminum alloy spare parts, medical equipment parts, instrumentation parts, precision machinery parts, communication and communication parts, electronic products High standards and high quality products in the industry of spare parts and auto parts.
Medical Instruments
Case: Aluminum alloy medical robot model production
Size: 30mm*1m
Accuracy: 0.01mm
Advantages: durability and precision
Mold Processing
With the rising labor costs, the preparation of mold templates in the past has been gradually replaced by CNC. Compared with the previous manual preparation, its advantages are: CNC machining holes and hole position relative position accuracy is higher, and work efficiency is extremely Great improvement. In addition, CNC machining processes are required for the machining of curved surfaces, profiled parts, and plastic mold forming cavities in metal molds.
Mold Processing
Smart Home
Case: Smart Service Robot
Production materials : ABS, acrylic, sheet metal, PMMA, 45 steel, magnet, aluminum alloy
Size: 1.6m
Accuracy: 0.01mm
Advantages: high precision, fast speed and high processing efficiency
Advantages of CNC Machining
High degree of automation and high production efficiency. Except for the manual clamping of the blank, all other processing can be done automatically by the CNC machine.
High production efficiency. CNC machine tools can shorten production preparation time and increase the ratio of machining time. Increase productivity by reducing machining time with optimum cutting parameters and optimal path.
It has strong adaptability to the processing object. When changing the machining object, Except to changing the tool and solving the blank clamping method, it only needs to be reprogrammed, and no complicated adjustment is required, which shortens the production preparation cycle.
High processing precision and stable quality. Machining dimensional accuracy is between 0.005 and 0.01 mm, independent of the complexity of the part. Most of the operations are done automatically by the machine, eliminating human error and increasing the consistency of batch part sizes.
A wide range of optional processing materials. The materials processed by CNC are relatively wide, including plastics and hardware.

Julian Franklin taught the kids all about Simple Machines in an exciting program with lots of audience participation!
This year, we are creating a Time Machine at Pataphysical Studios, with a world-class team of of artists, makers, engineers and multimedia innovators.
This interactive art exhibit invites you to travel through time and meet characters from the past, present and future. We hope to intrigue, enchant and engage visitors in a playful experience that combines interactive art, multimedia theater and technology.
These first designs illustrate the experience we are creating. We will invite our guests to go through a short interactive ritual during their visit: walk around the exhibit, step into a magic portal, pick a time to visit, travel to that time, meet its characters and return back to the present.
This is the most complex art project we have ever created together. We are now working in teams to design and build different parts of the Time Machine, making interactive art with lights, sound and motion powered by Arduino and Raspberry Pi -- as well as producing short videos of the different times you will travel to.
We're all excited about our next collective art project and can’t wait to see what it will look like in a year!

I was going through some old boxes in the basement and was excited to find this. It is a portable (and very manual) adding machine that would have been used before caculators were available/affordable. Based on an Internet search, it appears this is from 1955. I think my great aunt gave it to me when I was a kid to play with.

my moms brought this over in a garbage bag for me :D
someone gave it to her and she already has 2 cabinet ones.
The new Old Town Armory & Heirlooms shop on the mall has a World War II Engima machine. The ability of the UK to break these cipher machines' code was hugely important in winning World War II. One recently sold for $200,000. This one is going up for auction soon. Check out www.facebook.com/oldetownearmory for more...

Experimental Sonic Machines is Peter K Rollings from Lincoln. He makes most his equipment from scrap materials & some are solar powered. ESM started in 2010 with abstract sounds at open mics, & has developed greatly since, now with music machines playing basslines & rhythms. In his shows he metamorphoses into beings seeming to be from other worlds & times, & the music is all original.

Image Description:
Frank Aston “Post Card Views”
Photographer Frank Aston was hired in 1906 to photograph Cal Poly. It was likely that he was the sole photographer hired by the school administration to generate the majority of the photographs used by Cal Poly in its annual circular or bulletins, and the in the student publication, the Polytechnic Journal. In the 1909 Polytechnic Journal, Aston advertised “Poly photos” for sale, which he sold in his studio at 5 cents each.
