GUESS WHO JUST GOT ACCEPTED INTO TRADE SCHOOL!!!!!

[trillscienceofficer]

they still make and sell CNC machine controllers with black-and-white cathode tube screens... hundreds of thousand of them in fact in 2024. apparently because continuity and retrocompatibility with machines from the 1970s is the priority in designing those. and my first thought of course was, I'm going to exploit this fact so much for my star trek fic

[univac1219]

1962 Mainframe with Bluetooth

This old computer is comprised of four big boxes, three of which are ever actually used.

The UNIVAC 1219. This is the brains of the system. It controls the operations of every other device. This is what I'm referring to when I'm not gesturing to the UNIVAC 1219 as a whole.

The UNIVAC 1540. This is the DDR, or Digital Data Recorder. It holds, writes, and reads the magnetic tape operators load into the machine.

The Digital to Analog Converter. The UNIVAC 1219 was the first digital computer on most U.S. Navy ships, most of which had analog weapons systems. This hulking mass of steel translated the digital signals from the computer to the analog signals of the weapon systems and vice versa in regards to the radar.

The UNIVAC 1532. The I/O console managed the...you guessed it, input and output of the UNIVAC 1219. You can load and punch paper tape for programs more bite-sized than would be used for magnetic tape.

In addition, we have two teletype machines. You can think of them like typewriters that don't receive human input (except the one that can if we want), but instead output what the computer tells it to.  We have a Teletype Corporation teletype that is optimized for character compatability and a Kleinschmidt teletype that is optimized for speed. Both rely on the I/O console to send and receive data.

The real ingenuity begins with the floppy drive. Duane, who's career revolved around this system, developed a way for a floppy drive to imitate the I/O console. The computer thinks it is reading and writing to a paper tape, when it is in fact reading and writing to a 5.25in floppy inside an ancient CNC machine floppy drive.

And this, dear reader, is where the magic happens. This framework was originally built for interfacing with the 1219 via BIN files over Serial port and was easily changed to support BIN files over floppy. Duane has been working on an off adapting our purple converter box with a raspi to let the 1219 read and write BIN files over Bluetooth.

Make no mistake, you cannot simply SSH into this machine as tons of setup and channel changes must be performed to ready it to receive and send data. That being said, I don't see any other UNIVAC mainframes with Bluetooth [or any other running UNIVAC 1219s at all :(], so I will take what I can get.

Can someone tell me how to Tumblr properly?

[transfemme-shelterdog]

I'm a trans guy who's currently working in a trade school, specifically taking a digital printing technology program (so like silkscreening, pre-press, embroidery, lazer cutting, label making, etc.) and when I see CNC I just automatically think about CNC (Computer numerical control) machine. It's basically a giant machine to cut stuff like wood, aluminum, film, foam, stuff like that.

Fun fact: I actually took a course in CNC programming in high school.

Funny anecdote but imagine being in University in a degree where you have to take psych classes at the height of "CBT" memes. Our professor would always talk about "Cognitive Behavioral Therapy" and my and my friends would have to not laugh because all we could think about was cock and ball torture.

idk what id do w/ myself in a professional or customer service setting . learn cnc machining you can scroll grindr on the clock while the program runs

[electropneumatic]

I'm very good at "professionalism" I was trained from a young age. If I get an interview, I'm getting the job. I sit upright in my chair and wear a collared shirt and my employer thinks, "wow! She has a lot of passion for this role!" Buddy, you don't know the start of it. You don't even know my gender.

I'm OSHA certified. I got my 24-hour GD&T training. They can see this. What they don't see is me waxing poetical about surface finish or some shit on this website. When I was in 6th grade, I was exposed to Autodesk Inventor and it changed me fundamentally as a person. Whenever I look at any consumer good (of which there are a lot) I have to consider how it was made. And where the materials came from and how it got here and really the whole ass process. It's fascinating to me in a way that can be described as "intense". I love looking at large machines and thinking about them and taking pictures of them. There are so many steps and machines and people involved to create anything around you. I think if any person truly understood everything that happened in a single factory they would go insane with the knowledge. But by god am I trying. My uncle works specifically on the printers that print dates onto food. There are hundreds or even thousands of hyperspecific jobs like that everywhere. My employer looks away and I'm creating an unholy abomination of R and HTML, and I'm downloading more libraries so I can change the default CSS colors. I don't know anything about programming but with the power of stack overflow and sheer determination I'm making it happen. Is it very useful? No. But I'm learning a lot and more importantly I don't give a fuck. I'm learning about PLCs. I'm learing about CNC machines. I'm fucking with my laptop. I'm deleting SQL databases. I'm finding electromechanical pinball machines on facebook marketplace. I'm writing G-code by hand. I'm a freight train with no brakes. I'm moving and I'm moving fast. And buddy, you better hope I'm moving in the right direction. I must be, because all of my former employers give me stellar reviews when used as a reference. I'm winning at "career" and also in life.

CNC development history and processing principles

CNC machine tools are also called Computerized Numerical Control (CNC for short). They are mechatronics products that use digital information to control machine tools. They record the relative position between the tool and the workpiece, the start and stop of the machine tool, the spindle speed change, the workpiece loosening and clamping, the tool selection, the start and stop of the cooling pump and other operations and sequence actions on the control medium with digital codes, and then send the digital information to the CNC device or computer, which will decode and calculate, issue instructions to control the machine tool servo system or other actuators, so that the machine tool can process the required workpiece.

‌1. The evolution of CNC technology: from mechanical gears to digital codes

The Beginning of Mechanical Control (late 19th century - 1940s)

The prototype of CNC technology can be traced back to the invention of mechanical automatic machine tools in the 19th century. In 1887, the cam-controlled lathe invented by American engineer Herman realized "programmed" processing for the first time by rotating cams to drive tool movement. Although this mechanical programming method is inefficient, it provides a key idea for subsequent CNC technology. During World War II, the surge in demand for military equipment accelerated the innovation of processing technology, but the processing capacity of traditional machine tools for complex parts had reached a bottleneck.

The electronic revolution (1950s-1970s)

After World War II, manufacturing industries mostly relied on manual operations. After workers understood the drawings, they manually operated machine tools to process parts. This way of producing products was costly, inefficient, and the quality was not guaranteed. In 1952, John Parsons' team at the Massachusetts Institute of Technology (MIT) developed the world's first CNC milling machine, which input instructions through punched paper tape, marking the official birth of CNC technology. The core breakthrough of this stage was "digital signals replacing mechanical transmission" - servo motors replaced gears and connecting rods, and code instructions replaced manual adjustments. In the 1960s, the popularity of integrated circuits reduced the size and cost of CNC systems. Japanese companies such as Fanuc launched commercial CNC equipment, and the automotive and aviation industries took the lead in introducing CNC production lines. 

Integration of computer technology (1980s-2000s)

With the maturity of microprocessor and graphical interface technology, CNC entered the PC control era. In 1982, Siemens of Germany launched the first microprocessor-based CNC system Sinumerik 800, whose programming efficiency was 100 times higher than that of paper tape. The integration of CAD (computer-aided design) and CAM (computer-aided manufacturing) software allows engineers to directly convert 3D models into machining codes, and the machining accuracy of complex surfaces reaches the micron level. During this period, equipment such as five-axis linkage machining centers came into being, promoting the rapid development of mold manufacturing and medical device industries.

Intelligence and networking (21st century to present)

The Internet of Things and artificial intelligence technologies have given CNC machine tools new vitality. Modern CNC systems use sensors to monitor parameters such as cutting force and temperature in real time, and use machine learning to optimize processing paths. For example, the iSMART Factory solution of Japan's Mazak Company achieves intelligent scheduling of hundreds of machine tools through cloud collaboration. In 2023, the global CNC machine tool market size has exceeded US$80 billion, and China has become the largest manufacturing country with a production share of 31%.

2. CNC machining principles: How code drives steel

The essence of CNC technology is to convert the physical machining process into a control closed loop of digital signals. Its operation logic can be divided into three stages:

Geometric Modeling and Programming

After building a 3D model using CAD software such as UG and SolidWorks, CAM software “deconstructs” the model: automatically calculating parameters such as tool path, feed rate, spindle speed, and generating G code (such as G01 X100 Y200 F500 for linear interpolation to coordinates (100,200) and feed rate 500mm/min). Modern software can even simulate the material removal process and predict machining errors.

Numerical control system analysis and implementation

The "brain" of CNC machine tools - the numerical control system (such as Fanuc 30i, Siemens 840D) converts G codes into electrical pulse signals. Taking a three-axis milling machine as an example, the servo motors of the X/Y/Z axes receive pulse commands and convert rotary motion into linear displacement through ball screws, with a positioning accuracy of up to ±0.002mm. The closed-loop control system uses a grating ruler to feedback position errors in real time, forming a dynamic correction mechanism.

Multi-physics collaborative control

During the machining process, the machine tool needs to coordinate multiple parameters synchronously: the spindle motor drives the tool to rotate at a high speed of 20,000 rpm, the cooling system sprays atomized cutting fluid to reduce the temperature, and the tool changing robot completes the tool change within 0.5 seconds. For example, when machining titanium alloy blades, the system needs to dynamically adjust the cutting depth according to the hardness of the material to avoid tool chipping.

‌3. The future of CNC technology: cross-dimensional breakthroughs and industrial transformation

Currently, CNC technology is facing three major trends:

‌Combined‌: Turning and milling machine tools can complete turning, milling, grinding and other processes on one device, reducing clamping time by 90%;

Additive-subtractive integration: Germany's DMG MORI's LASERTEC series machine tools combine 3D printing and CNC finishing to directly manufacture aerospace engine combustion chambers;

‌Digital Twin‌: By using a virtual machine tool to simulate the actual machining process, China's Shenyang Machine Tool's i5 system has increased debugging efficiency by 70%.

From the meshing of mechanical gears to the flow of digital signals, CNC technology has rewritten the underlying logic of the manufacturing industry in 70 years. It is not only an upgrade of machine tools, but also a leap in the ability of humans to transform abstract thinking into physical entities. In the new track of intelligent manufacturing, CNC technology will continue to break through the limits of materials, precision and efficiency, and write a new chapter for industrial civilization.
