2. Bridgeport (machine tool brand) - Wikipedia

   en.wikipedia.org/wiki/Bridgeport_(machine_tool...

   Currently R8 and Erickson #30 Quick Change tool holders are available. Machine slides are of the dovetail type, and rotary bearings are mostly of the roller and ball types. Through 1970, Bridgeport turret milling machines were made under licence by Adcock-Shipley, a UK manufacturer of horizontal and vertical milling machines founded during WW1.

3. Collet - Wikipedia

   en.wikipedia.org/wiki/Collet

   R8 collets were developed by Bridgeport Machines, Inc. for use in milling machines. Unusually, R8 collets fit into the machine taper itself (i.e. there is no separate chuck) and tools with integral R8 taper can also be directly fitted. R8 was developed to allow rapid tool changes and requires an exact match between collet and tool shank diameter.

4. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

5. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers : milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures.

6. Kearney and Trecker - Wikipedia

   en.wikipedia.org/wiki/Kearney_and_Trecker

   In 1965 the company was a leading automated tool maker, and had annual sales of more than 47 million dollars. They manufactured more than 100 different boring and milling machines. They merged with the Rockwell-Standard corporation in 1965. [6] By 1955 the company had grown to become one of the largest machine tool suppliers in the world.

7. Multiaxis machining - Wikipedia

   en.wikipedia.org/wiki/Multiaxis_machining

   CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.
