Step by Step Machining Process to Make Spurgear. Gear manufacturing refers to the making of gears. Gears can be manufactured by a variety of processes, including casting, forging, extrusion, powder metallurgy, and blanking. As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear. The initial operations that produce a semifinishing part ready for gear machining as referred to as blanking operations; the starting product in gear machining is called a gear blank.
In form milling, the cutter called a form cutter travels axially along the length of the gear tooth at the appropriate depth to produce the gear tooth. After each tooth is cut, the cutter is withdrawn, the gear blank is rotated, and the cutter proceeds to cut another tooth. The process continues until all teeth are cut.
Broaching can also be used to produce gear teeth and is particularly applicable to internal teeth. The process is rapid and produces fine surface finish with high dimensional accuracy. However, because broaches are expensive and a separate broach is required for each size of gear,this method is suitable mainly for high-quality production.
In gear form cutting, the cutting edge of the cutting tool has a shape identical with the shape of the space between the gear teeth. Two machining operations, milling and broaching can be employed to form cut gear teeth.

Vraiment merci beaucoup pour tout!!!.
Very cool process. Not gonna lie though, I was sweating bullets watching him adjust the runout in the chuck *while* the machine was moving. Nothing mangles an arm quite like a large machine with insane torque. 😥
👍
Climb cutting instead of conventional cutting will increase your tool life and give you a better surface finish.
Thanks for information
beau travail merci !!
Sir Explain gear index calculation
Hey there! Ready to learn about gear index calculation? Let's make it simple and fun!
Bom dia, bom trabalho.
Você poderia me informar de qual país está postando este vídeo?
Que bien!!! una talladora Tos y realizó los dientes o tallado de un eje para un torno de la misma marca Tos Trencin (Checoslovaco) lo conozco bien. Muy buena marca.😉
¡Qué emocionante! Es genial saber que tienes experiencia con una talladora Tos y que has realizado el tallado de un eje para un torno de la misma marca. Tos Trencin es conocida por su calidad y durabilidad, por lo que no es sorprendente que tengas una buena opinión de ella. ¡La precisión y la calidad de las herramientas son fundamentales en la industria de la fabricación! 😊
Este o muncă tehnică 👍🙋♂️
Thanks
Why did you mount change gears on the differential compound if you cut a spur gear on the FO6...👀👀
Its a requirement of Hobbing machine setting... Though we all know differential gear are for helix angle but still we have to adjust change gear in differential section by maintaining "0" degree
Nice video, shows that old machines can still make good parts!!
It looks like thin cooling oil, not heavy cutting oil. Maybe an attention point.
Thanks for comment
How does one determin the angle the hobb axis must be on to produce an involute gear is it the pitch angle across the OD of the hobb, or an cmplimentary angle at 90 to that?
To produce an involute gear using a hobbing process, you need to determine the angle of the hob axis correctly. The angle you need to consider is called the "hob pressure angle" or "hob angle." It is not the pitch angle across the outside diameter (OD) of the hob, nor is it the complementary angle at 90 degrees to the pitch angle.
The hob pressure angle is the angle between the hob's teeth and a line perpendicular to the gear's axis at the point of contact. It is a critical parameter in gear hobbing because it affects the shape of the gear tooth profile and influences the gear's performance.
Here are the steps to determine the hob pressure angle:
1. Understand the Gear Specifications: Determine the required specifications for the involute gear you are producing. This includes the module or diametral pitch, the number of teeth, the pressure angle, and any other relevant parameters.
2. Choose the Pressure Angle: The pressure angle is specified in gear design and can range from typically 14.5 degrees to 30 degrees, with 20 degrees being a common standard. Select the pressure angle according to your gear design requirements.
3. Set the Hob Angle: The hob angle is typically equal to the pressure angle. In other words, the hob's teeth are angled at the same degree as the specified pressure angle. This ensures that the hob generates gear teeth with the correct involute profile.
4. Align the Hob: When setting up the hobbing machine, make sure the hob axis is aligned with the gear's axis and that the hob angle matches the specified pressure angle.
5. Hob the Gear: With the hob properly aligned and set to the correct angle, you can proceed with the hobbing process to cut the gear teeth.
In summary, the hob angle, also known as the hob pressure angle, should match the specified pressure angle for the gear you are producing. It is not the pitch angle across the OD of the hob or its complementary angle at 90 degrees to the pitch angle. Aligning the hob at the correct pressure angle ensures that the hob generates gear teeth with the desired involute profile.
@@WorkMachineEquipmentTechnology awesome thanks for the lengthy reply
sounds like its time for lunch 8:12

What kind of surface finish is that?
it is so fucking bad
🤔
nice video.i have a plan to buy a gear hobbing machine but the problem we dont know how to compute the change gear train..is there any formula on how to compute?
You contact Any mechanical engineer in your area...
Every Hobbing machine has its own calucated value in form of certain digit.. you may find it on the respective catalogue of the machine for Indexing and for differential..
@@RajRaj-dl5xm Right
climb cut if you want a better finish. that looks like crap. if youre gear grinding of course dont worry but youre not using a protuberance hob. and your rake on the cutters is crazy too. youve got heaps of rake. it changes the actual pressure angle that its cutting.
I appreciate your feedback and suggestions regarding the machining process. Climb cutting can indeed result in a better finish, as it reduces the chances of chip buildup and can provide smoother cutting action. However, it's important to note that climb cutting can be more aggressive and may require careful consideration of factors such as machine stability, tooling condition, and workpiece material.
Regarding gear grinding, if that is the process you're referring to, the approach can differ from conventional milling or hobbing methods. Gear grinding typically involves the use of specialized grinding wheels and machinery to achieve precise tooth profiles and surface finishes.
Regarding the protuberance hob and rake on the cutters, it's essential to select the appropriate tooling based on the specific requirements of the job. Different cutting tools and geometries are designed for various applications and materials. The rake angle plays a role in determining the cutting forces, chip evacuation, and surface finish. It is necessary to consider the design and specifications of the gear being cut to select the most suitable cutting tools.
Ultimately, machining processes can be complex, and various factors come into play when determining the best approach. It's crucial to consider factors such as the type of gear, material, machine capabilities, tooling, and desired outcome when selecting the most appropriate cutting strategy.

Sir wat is lead of pfouter rh2 lead formula
I would like to talk to you about permission to use some of your videos for a gear design class I am creating. I would like to use a video on hobbing, shaping and broaching. I know you have several on hobbing. Do you have any shaping videos? Do you have any broaching videos? How may I obtain permission to use them? Thanks
Where are you show my Video?
@@WorkMachineEquipmentTechnology it will be part of a web-based gear design class. The class is being created in collaboration with Universal Technical Systems, makers of IGS, a gear design software. The video will still reside on UA-cam , and I will provide a link to the video to allow students to understand how gears are manufactured. The link will reside on the UTC Learning Center web site. No changes to the video are intended or required.
