fly cutter

A fly cutter is composed of a body into which one or two tool bits are inserted.

Most fly cutters simply have a cylindrical center body that holds one tool bit.

Fly bars are perhaps a bit more dangerous to use than endmills and regular fly cutters because of their larger swing.

Fly cutters are a type of milling cutter in which one or two tool bits are mounted.

Regular fly cutters (one tool bit, swept diameter usually less than 100 mm) are widely sold in machinists' tooling catalogs.

He also provides a citation on how the introduction of vertical mills brought about wider use of the endmill and fly cutter types.

The applied photoresist is then milled down to the precise height by a fly cutter prior to pattern transfer by X-ray exposure.

Tools using inserts include milling cutters (endmills, fly cutters), tool bits, and saw blades.

Fly Cutter (Jumping cutter)

Fly cutters are analogous to face mills in that their purpose is face milling and their individual cutters are replaceable.

Other tools such as drill chucks, fly cutters, indexable insert cutters, etc. may have an R-8 taper shank built into or added to the tool.

Fly cutters are an application of tool bits where the bits are part of a rotary unit (whereas most other tool bit use is linear).

Further, the cutting of the PMMA sheet by the fly cutter requires specific operating conditions and tools to avoid introducing any stress and crazing of the photoresist.

Fly cutters with two tool bits have no "official" name but are often called double fly cutters, double-end fly cutters, or fly bars.

Face mills are more ideal in various respects (e.g., rigidity, indexability of inserts without disturbing effective cutter diameter or tool length offset, depth-of-cut capability), but tend to be expensive, whereas fly cutters are very inexpensive.

Cutting with a hole saw is analogous to some machining operations, called trepanning in the trade, that swing a cutter analogous to a fly cutter in order to achieve a similar result of annular kerf and intact core.
