Forging, especially drop forging, is better than machining for several reasons. Firstly, forging produces parts with superior strength and durability compared to machined parts, as the process aligns the grain structure of the metal, resulting in increased strength. Additionally, forging can produce parts with complex shapes and intricate details that would be difficult or impossible to achieve through machining. Furthermore, forging is a more efficient process in terms of material usage, as it produces less waste compared to machining. Overall, forging, and drop forging in particular, offers numerous advantages in terms of part strength, complexity, and material efficiency compared to machining. **

Free forging involves shaping metal by applying compressive forces using hammers or presses without the use of any specific dies or tools. This method allows for more flexibility in shaping the metal but may result in less precise dimensions. On the other hand, die forging involves shaping metal using dies or molds to achieve specific shapes and dimensions. This method provides more control over the final product's dimensions and surface finish, making it suitable for mass production of parts with consistent quality. **

The Kitchen Aid Artisan mixer may squeak due to a few reasons. One common cause is that the gears inside the mixer may need to be lubricated. Another reason could be that the attachments are not properly secured, causing friction and noise. Additionally, if the mixer is being used at a high speed for an extended period of time, it may also start to squeak. Regular maintenance and proper usage can help prevent the squeaking noise. **
