@alanhowitzer the machines that make the gears are CNC (computer numeric control) machines in other words programmable machines, they are or were made by hand at one point which made them expensive and so werent very common then as more CNC machines were made they too could make parts for CNC machines and other mechanical applications So what started as a purely human task requiring immense amounts of time and money is now mainly a machine based job but it costs a lot!

Secondary machining, like you said, is used a lot for when a powdered metal part has a mating surface to another part or needs holes drilled, threaded, or extreme tolerances. However, majority of pm parts, including gears, are finished once they are sintered. I've run a few secondary jobs through my shop in the past. I've had the great misfortune of being stuck in the tool and die end of this industry for 20 years, lol. It has paid some bills I guess, but I hate it with a passion.

dtlssm The first gears were made with ink, compass, scribe and file. You would use the compass to scribe a circle in the ink. Cut most of the excess off, leaving a little so it’s easier to make marks on the perimeter of the circle scribe. Then you would set the angle of the compass to a smaller size, estimating based on the size of teeth you expect. Then you would walk the compass around the perimeter, scribing as you go. If the compass was set too big, then reduce the angle and try again (redo the ink so only the new scribe marks shine). Rinse and repeat until you’re satisfied that the markings are accurate enough. Then sand/file the rest of the excess off. Now you have a circular slab with markings around the circumference. At this point, you file each tooth to your satisfaction. This is a lot of work to do, and it is very difficult to get consistent teeth. That’s why you would use a shaper, like Sarvesh says above. A shaper is just a machine with a table and vice, and it has a reciprocating arm which you mount cutters on. Your are able to move the vice up and down so that you only cut a little at a time. This way, you can at least get consistent teeth, but only straight, no helical gears. Similarly, a mill can be used to cut the teeth using a vertical rotary table. Now because the original procedure of marking out the teeth being so tedious, and with limited precision (you can do pretty good, but in automotive and similar applications, really high precision is needed if you want quiet smooth meshing), people made indexers, which can be used to rotate a very specific amount. The critical part of these is an indexing plate, which you can either buy, or make using that original marking procedure. Usually a thread is used that makes the table turn once every 40 turns of the handle, or some similar number, so the precision of the original marking method is increased by that amount. Helical gears can be made by coupling the travel of the mill table (with, you guessed it, a bunch of gears) to the rotary table, so that it rotates an amount proportional to the travel of the table. This also means that the pitch of the cutter needs to be set appropriately. TL;DR People with a LOT of elbow grease and determination
@14959787076 жыл бұрын
dtlssm The way that they show here is the way that factories make gears. Machinists do things quite differently usually. This is because a factory needs to make thousands of the same exact part, while a machinist generally needs to make completely custom parts. So a factory can afford to spend 10 thousand dollars on a gear cutting machine that can only cut a certain type of gear, while a machinist will do things a slower and less efficient way, because they cannot afford a ten thousand dollar machine for every new order they take. A gear hobber on its own is a quite expensive piece of equipment, and it can only be used to cut a specific gear. So machinists pretty much never use them. If you’re a real DIY kind of person, you could make a basic disk shaped gear cutter (only cuts one groove at a time) without much difficulty, but professional machinists would usually just buy a set of this type of gear cutters, because you can use such a set to cut most of the gears you might need to.

They make them on a different machine, duh. But I'm not sure what makes the gears in *that* machine. ;-) I did once see a fascinating documentary, one small part of which was a little old mad-scientist-type man who was making gears with very specific numbers of teeth from sheet brass, using only tin snips, a pair of dividers, a file and a magnifier. He was incredibly skillful and wonderful to watch. I think he said it took about 15mins to make a gear that could go in a clock.

Because the number of teeth on the gear and the angle at which they might have a "helical cut" is different every time. You'd have to have a sand casting and pattern for each one. It's quicker to just cut them using tools and a lathe.

@31Orcas11 жыл бұрын
Yes, it would be quicker, but it would be close to impossible to get it to the right shape. Air bubbles, thermal expansion, and surface tension naturally work together to make sure that filling a mold results in a sloppy, inaccurate lump of metal (in comparison to milling as seen here) instead of a precise mechanical component, unfortunately.

Corn doesn't have high levels of calcium. Eagles, seagulls, etc. don't eat corn, but they lay calcium shelled eggs. The birds that peck at the roadside are getting stones for the gizzard but may also be getting magnesium, etc. to 'transmute' into calcium. Bone eating vultures get lots of calcium. Anyway, not all birds depend on man for food. Tricalcium phosphate is the best dietary form of calcium. I guess it doesn't matter.
