Processing & Inspection Machine List.pdf

^{A rack is a special gear with teeth distributed on a bar. Racks are
also divided into spur racks and helical racks, which are used in
pairs with spur and helical spur gears respectively; the tooth
profile of the rack is straight rather than involute (flat for the
tooth surface) , which is equivalent to an infinite cylindrical
gear with an indexing circle radius. A rack is a bar-shaped part
matched with a gear. It is equal to a segment of the circumference
of a gear with an infinite diameter. There are many teeth evenly
distributed on one side, which mesh with gears and turn rotation
into movement, or movement into rotation. The rack is a long bar
with teeth on one side, which can be considered as a segment on a
gear with an infinite diameter.}

^{The rack has the following characteristics:}

^{(1) Since the rack tooth profile is a straight line, each point on
the tooth profile has the same pressure angle, which is equal to
the inclination angle of the tooth profile. This angle is called
the tooth profile angle, and the standard value is 20°.}
^{(2) Any straight line parallel to the addendum line has the same
pitch and module.}
^{(3) The straight line parallel to the tooth top line and the tooth
thickness equal to the tooth slot width is called the index line
(center line), which is the reference line for calculating the rack
size.}

FAQ:

^{Q1: What are the types of EDM process?
A: Electric discharge machining can be divided into three common
types, Die sinking EDM, Wire EDM and hole drilling EDM.
Die sinking EDM.
Wire EDM.
Hole drilling EDM.}

^{Q2: What does EDM stand for in machining?
A: Electrical discharge machining (EDM), also known as spark
machining, spark eroding, die sinking, wire burning or wire
erosion, is a metal fabrication process whereby a desired shape is
obtained by using electrical discharges.}

^{Q3: Which material is used for EDM process?
A: Electrodes that are generally used in EDM process are copper,
graphite, copper tungsten, silver tungsten, tungsten carbide,
brass.}

^{Q4: What is application of EDM?
A: The EDM process is most widely used by the mold-making, tool,
and die industries, but is becoming a common method of making
prototype and production parts, especially in the aerospace,
automobile and electronics industries in which production
quantities are relatively low.}

^{Q5: What are the advantages of EDM?
A: Creates complex shapes that would otherwise be difficult to
produce with conventional cutting tools. Cuts extremely hard,
challenging and exotic materials to very close tolerances for high
precision mechanical components.}

^{Q6: What is the difference between EDM and wire EDM?
A: Conventional EDM cannot produce narrower angles or more complex
patterns, while wire-cut EDM can be performed. A more precise
cutting process allows for more complex cuts. The wire EDM machine
is capable of cutting a metal thickness of about 0.004 inches.}
