Whether in automobiles, industrial machinery, or consumer products, gears play a central role in transferring power and motion efficiently. Gear machining ensures that these components are crafted with precision, allowing for smooth operation and long-lasting performance.

What is Gear Machining? Gear machining refers to the process of cutting and shaping metal or other materials to create gears with specific dimensions, teeth profiles, and tolerances. This process involves several techniques, including hobbing, milling, broaching, and grinding, each suited for producing different types of gears such as spur, helical, bevel, and worm gears. The choice of method depends on the gear's size, material, and intended application.

Key Methods of Gear Machining:

Hobbing: This is one of the most common methods for gear cutting. A hob (a cylindrical cutting tool) rotates and cuts the teeth into the gear blank, producing accurate, evenly spaced gear teeth. It's widely used for producing spur and helical gears.

Gear Grinding: For high-precision gears, grinding is used to achieve tight tolerances and smooth finishes. This method is typically employed for gears that require high levels of accuracy, such as in aerospace or automotive applications.

Broaching: This method is often used for cutting internal gear teeth. A broach tool is pushed or pulled through the material to create precise internal shapes.

Importance of Precision in Gear Machining: Precision in gear machining is essential for ensuring smooth transmission of power and reducing friction between moving parts. Poorly machined gears can lead to noise, excessive wear, and system failure, making it crucial to adhere to strict tolerances during the manufacturing process.

Conclusion: Gear machining is a critical aspect of modern manufacturing, ensuring that gears function efficiently and reliably in various mechanical systems. With advanced machining techniques like hobbing, grinding, and broaching, manufacturers can produce high-precision gears that meet the demands of today's technology-driven industries.

Laser Engraving Through Leading-edge Machines

Inscription done by using Laser beam can be categorised into 3 major categories. Although the three categories sound similar, they are different in their procedures and methods and are altogether based on the level of actions that are reflected on the engraving materials. The first method is the laser marking; here the laser beam used to carry out the marking, just fades away a part of the material surface leaving a comparatively lighter area than its surroundings so that the information is clearly visible. But however this method can be used on selective materials where the markings must be up on to the surface only.

The second method is the laser engraving. In this method the information that has to be displayed is deeply engraved, by removing a calculated outer surface of the engraving material to certain depth. This ensures that the engraving is quite permanent and solid. Then the third method is laser etching. In this method a certain amount of the engraving material is carefully removed by subjecting it to a certain amount of heat, in form of a fine pointed tip, so that the engraving material surface is removed precisely with a fine finish. So in a way engraving is marking or writing on the surface of the material, with various degrees of impact.

Being a method where in the the intensity of the laser beam used will be quite lower, a negligible amount of heat is generated thereby ruling out any rise in temperature of the surface. Even in this spite where it can be used on delicate surfaces that may otherwise get spoiled by the temperature, it is less commonly implemented. The other method that is the laser engraver is the involvement of quite a good amount of heat, which is used to almost evaporate the amount of engraving material surface. Since this method uses high levels of heat, it cannot be used on materials that are less resistant to higher temperatures. But however it is an ideal methodology for parts that are subject to wear and tear. Certain engraving material, tend to change their surface properties along with increase in temperature, this method can be employed in cases where the fear of temperature related is nil.

Industries like Signvec, who deal with Engraving materials and products, offer laser based technological machinery such as laser cutter, engravers like rotary engravers and engraving machines, and the CNC engraving machine, is the one which employs the computer based laser cutting and engraving.

Sticker Cutter Research

I was looking into getting a sticker cutting machine, and I decided to start by looking into cricut which is a well known brand. I had a look at what models they had than their feature etc, but what I was most concerned about was their software. Printer companies like to lock you into a defacto subscription to support hardware you don't really own, and as I was to discover, cricut are operating in a similar way.

The cricut software is online-only*. To cut your own designs you need to use their software to upload your art to their server. There's no way to cut a new design without a logged-in cricut account and an internet connection. At one point in 2021 they flirted with limiting free accounts to 20 uploads/month but backed down after huge community backlash, as far as I can tell.

The incident spawned several community efforts to write open-source firmware for cricut hardware. Some efforts were successful for specific models/serial numbers, but require cracking open the case and hooking in to the debug contacts to flash the chip; not exactly widely accessible. Another project sought to create a python cricut server you can run locally, and then divert the app's calls to the server to your local one.

I restarted my search, this time beginning with looking for extant open-source software for driving cutters, and found this project, which looks a little awkward to use, but functional. They list a bunch of cutter hardwares and whether they're compatible or not. Of those, I recognised the sihouette brand name from other artists talking about them.

I downloaded the silhouette software to try like I did w the cricut software, and immediately it was notable that it didn't try to connect to the internet at all. It's a bit clunky, in that way printer and scanner software tends to be, but I honestly greatly preferred using it to cricut's sluggish electron app⁺. Their software has a few paid tiers above the free one, adding stuff like sgv import/export/and reading cut settings from a barcode on the input material. They're one-off payments, and seem reasonable to me.

This is not so much a review, as sharing some of the research I've done. I haven't yet used either a cricut or a silhouette, and I haven't researched other brands either. But I wanted to talk about this research because to me, cricut's aggressively online nature is a red flag. Software that must connect to a server to run is software that runs only at the whim of the server owner (and only as long as it's profitable to keep the server up). And if that software is the only thing that will make your several hundred dollars worth of plastic and (cheap, according to a teardown I read) servos run, then you have no guarantee you'll be able to run it in the future.

Do you use a desktop cnc cutter? What has your experience been like with the hardware and software? Do you have any experience from home printers with good print quality and user-refillable ink cartridges?

* Cricut's app tried to connect to more than 14 different addresses, including facebook, youtube, google analytics, datadoghq.com, and launchdarkly.com. Launch Darkly are a service provider that help software companies do a whole bunch of things I'm coming to despise, for example, they offer infrastructure for serving different features to different demographics and comparing results to control groups. You know how at various times you've gotten wildly different numbers of ads than your friends on instagram? They were using techniques like this to work out how many ads they could show without affecting their pickup/engagement rates. Scummy stuff.

⁺ Electron apps are web-pages pretending to be applications. They use heaps of ram, tend to have very poor performance, and encourage frustrating UI design that doesn't follow OS conventions. Discord's app is a notable example of an Electron app

[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.

I didn't go to class because It's a holiday here in my country, the first pic is a picture of a machine I used this week, It is a CNC machine, made to create molds and cut materials.

Today I studied Adjectives and Adverbs in Russian, and I feel like I'm slowly improving.

[practicalsolutions]

I was tagged by @sleightlyoffhand to list 5 topics I can talk on for an hour without preparing any material. You asked for it.

3D printing. This one was too easy. I could talk specifics of FDM machines and materials, or vaguely about other types. These range from SLS to DLP, to more niche high price models I'll never see irl except once. Like anything from Stratasys. Who I used to hecking idolize for having one of the first patents for 3D printing, other than the guy who came up with SLA.

CNC machines. This is probably an extension of 3D printing, as most FDM machines work pretty similar to most CNC mills, engravers etc. The code is the same (gcode). It can be easily written for simple processes like cutting, facing, and drilling. But, just as a slicer program converts 3D models to gcode, there are programs out there for turning 3D information into CNC gcode. It's just a subtractive process instead of an additive one.

The consequences of technology. Especially AI. It may be the best and worst thing to happen to humanity. I could rant about all the wonderful and horrible things that could arise, but it is probably better for both of us if I don't.

Minecraft. Maybe I quit lately, but I could still talk about the history from beta onwards. At least up until whatever update added the chat moderation. I really like pistons (old update) and I really like the bees (is that still considered new?). I love automatic farms, but they are more fun when you have a team that can use them. Don't get me started on redstone, or it will turn into a ramble about electronics and logic gates.

Crash Bandicoot. This place is not a place of honor. No highly esteemed deed is commemorated here. Nothing of value is here. What is here was dangerous and repulsive to us.

Pipe Bending Masterclass: The Science and Craft Behind Perfect Bends

Pipe bending is a critical process in various industries where precise pipe configurations are required for functionality, aesthetic purposes, or optimal fluid flow. One of the most precise fabrication methods used for this purpose is mandrel pipe bending, which is designed to avoid distortion, wrinkling, or collapse of the pipes. The process ensures that pipes are bent smoothly, maintaining their structural integrity and allowing for high-quality outputs. Let's explore the intricacies of mandrel pipe bending, including the types of mandrels used, the machinery involved, and why this method is preferred over other bending techniques, particularly in industries such as automotive and aerospace.

Understanding Mandrel Pipe Bending Mandrel pipe bending is a specialized technique where a mandrel, which is a rod or support, is inserted into the pipe during the bending process. The role of the mandrel is to maintain the interior shape of the pipe as it bends, preventing it from wrinkling, collapsing, or otherwise distorting. This is crucial when working with thinner pipes or when a pipe needs to be bent to a tight radius.

When pipes are bent without the support of a mandrel, they are susceptible to deformation, which can compromise their integrity and reduce their efficiency. This method, therefore, has become essential in ensuring precision and quality for industries where smooth fluid dynamics and consistent pipe dimensions are key.

Types of Mandrels Used in Pipe Bending Different types of mandrels are used in mandrel pipe bending, each serving a particular purpose based on the pipe's properties and the desired bend radius. The most commonly used types include plug mandrels, ball mandrels, form mandrels, and sand mandrels.

The plug mandrel is the simplest type, providing basic support for less challenging bends. It is often used when the pipe material is not prone to significant deformation. On the other hand, the ball mandrel, also known as the flexible mandrel, consists of multiple interconnected balls that offer greater flexibility. This type is ideal for bending pipes that require intricate curves, as the interconnected balls move with the pipe, allowing for smooth bends without compromising its shape.

Form mandrels, also called solid rods, provide robust support throughout the length of the bend. These mandrels are typically used when very precise bends are required, offering continuous support that minimizes the risk of deformation. Sand mandrels, while less common, involve filling the pipe with sand before bending. This method is suitable for specific applications where internal support is necessary, but other mandrel types are not viable.

The choice of mandrel depends on factors such as the material of the pipe, its thickness, and the required bend radius. Using the appropriate mandrel ensures the pipe maintains its roundness, preventing issues like ovality or buckling that could affect the pipe's performance.

Machinery Used in Mandrel Pipe Bending Mandrel pipe bending requires specialized machinery designed to accommodate the mandrel and apply the necessary force to bend the pipe accurately. CNC pipe benders, rotary draw benders, and hydraulic benders are the primary types of machines used in this process.

CNC (Computer Numerical Control) pipe benders are popular for mandrel bending due to their high precision and repeatability. These machines are capable of producing consistent bends, making them ideal for projects that require intricate bends or high volumes. By using a CNC machine, manufacturers can achieve tight tolerances and ensure that every bend is identical to the specifications.

Rotary draw benders use a fixed radius die to bend the pipe around a predetermined form. The mandrel is inserted into the pipe to provide internal support during the bending process, ensuring the bend is smooth and consistent. This method is commonly used in industries like automotive, where precise bends are critical to the performance of components like exhaust systems.

In some cases, hydraulic benders may be used in combination with a mandrel for heavy-duty applications. These machines provide the power required to bend thick or large-diameter pipes while ensuring accuracy. The use of advanced machinery in mandrel pipe bending helps minimize waste and produce high-quality output.

Why Choose Mandrel Pipe Bending? Mandrel pipe bending is preferred over other bending methods for several important reasons. First and foremost, this technique prevents deformation of the pipe, such as wrinkling or collapsing, which is particularly crucial when working with thin-walled pipes or achieving tight radii. When pipes are bent without sufficient internal support, they are more likely to suffer from these issues, compromising their structural integrity. The mandrel effectively eliminates this problem by providing internal reinforcement during the bend.

Another significant advantage of mandrel pipe bending is its high precision. Industries like automotive and aerospace require consistent and accurate bends to ensure components fit perfectly and function as intended. In these industries, even minor inaccuracies can lead to significant issues in performance and safety. Mandrel bending ensures that pipes meet the exact specifications required, reducing the risk of malfunction or failure.
