Hobbing Meaning: Definition, Examples, and Translations
⚙️
hobbing
[ˈhɑb.ɪŋ ]
Definition
manufacturing process
Hobbing is a machining process for creating gears, splines, and other parts with a specific profile. This process involves cutting material using a rotating hob, which is a specialized cutting tool shaped like a gear. Hobbing is known for its efficiency and precision, making it a preferred method for mass production of gears. The process allows for high-speed production and can handle a variety of materials, from soft plastics to hard metals.
Synonyms
gear cutting, machining, profiling.

Interesting Facts
Technology
- Hobbing is now a standard technique in producing gears and splines for various machinery.
- Modern hobbing machines are computer-controlled, allowing for precision and complex shapes to be created more efficiently.
- The process can produce both external and internal gear teeth with varying sizes and specifications.
Manufacturing Processes
- It's one of several methods used in machining, alongside milling, turning, and grinding, to fabricate parts.
- The technique is favored for its speed and ability to produce large quantities of gear parts in a single operation.
- Hobbing generally uses a cylindrical tool, which rotates as it engages with the workpiece to carve out gear shapes.
History of Engineering
- With the advent of hobbing, production timelines for gears decreased significantly, accelerating the progress of mechanical engineering.
- Pioneers in the late 1800s recognized the need for efficient gear production, leading to innovations in hobbing machines.
- This method contributed greatly to the development of the automobile and manufacturing industries, effectively changing transportation.
Types of Hobbing
- There are different types of hobbing machines, including automatic and manual setup based on the production requirements.
- Hobbing can be categorized into continuous and interrupted, targeting different production needs and efficiencies.
- Specialized tools called 'hobs' vary in shape and design, allowing for the production of unique gear profiles.
Origin of 'hobbing'
Main points about word origin
- The term 'hobbing' originated from the word 'hob,' which refers to a tool used in the process of shaping metal.
- Historically, 'hob' traces back to Old English, indicating a machine or device that aids in work.
- The practice of hobbing began around the 19th century alongside the industrial revolution, improving manufacturing processes.
The term 'hobbing' originates from the early 19th century, derived from the term 'hob', referring to the specific cutting tool used in the process. The use of hobs in machinery became more widespread with the industrial revolution as the demand for precision-engineered components increased. Initially, hobbing was a manual process, but advancements in technology have since allowed for automation and increased efficiency. By the late 1800s and early 1900s, hobbing machines were being developed and patented, leading to more refined techniques that we use today. Over the years, hobbing has evolved significantly, incorporating sophisticated computer numerical control (CNC) technology to enhance precision and reduce production times.
