The document discusses various gear manufacturing processes including extrusion, stamping, sintering, injection molding, cold drawing, and forging. Extrusion involves drawing material through a die to give it a constant cross-sectional shape, and can be used to make small gears from materials like aluminum and copper alloys. Stamping uses sheet metal and dies to form low-precision gears in large quantities for applications like toys and clocks. Sintering compacts metal powder in dies, then sinters the compact to form small gears while injection molding makes nonmetallic gears from plastics like nylon for uses where lubrication is not needed.

Cutting Strategies for Casting Die Manufacturing on CNC Milling MachineIOSR Journals
Manufacturing of dies has been presenting greater requirements of geometrical accuracy,
dimensional precision and surface quality as well as decrease in costs and manufacturing times. Although
proper cutting parameter values are utilized to obtain high geometrical accuracy and surface quality, there may
exist geometrical discrepancy between the designed and the manufactured surface profile of the die cavities. In
milling process; cutting speed, step over and feed are the main cutting parameters and these parameters affect
geometrical accuracy and surface quality of the casting die cavities. In this paper, effects of the cutting
parameters on geometrical error have been examined on a representative die cavity profile. To remove
undesired volume in the die cavities, available cutting strategies are investigated. Finish option for roughing
and finish option for finishing are optimized to reduce the Machining time of the cutting process thereby
decreasing the cost of cutting process. The cutting parameters considered are Cut Feed, Step Depth, Spindle
Speed for both roughing and finishing, scan type for roughing and lace type for finishing.3D model and
manufacturing process is done in parametric modeling software Pro/Engineer wildfire5.0.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Extrusion Process
Stamping Process
Sintering Process
Injection Molding Process
Cold Drawing Process
Forging Process
3. It is a manufacturing process where material is drawn through
a die, giving the material a new cross-sectional shape that is usually
constant throughout the lengths of the material. Dies with multiple
openings can extrude several strands simultaneously, as well as
create hollow cross-sections by using a pin (mandrel) in the die.
Extrusion
4. Extrusion process is used to form teeth on long rods, which are
then cut into usable lengths and machined for bores and keyways
etc. Nonferrous materials such as aluminum and copper alloys are
commonly extruded rather than steels. Results in good surface
finish with clean edges and pore free dense structure with higher
strength
Small sized gear can also be made by extrusion process. There is
saving in material & machining time.
This method can produce any shape of tooth & it is suitable for
high volume production. Gears produced by extrusion find
application in watches, clocks, type writers etc.
5. Sheet metal can be stamped with tooth shapes to form low
precision gears at low cost in high quantities. Surface finish
and accuracy are poor.
Stamping
Precision Stamping
The dies are made of higher precision with close tolerances.
The stamped gears will not have burrs.
Application
Toy gears, hand operated machine gears, slow speed
mechanism gears
Clock gears, watch gears etc.
Application
6. After stamping, the gears are shaved; they give best finish &
accuracy.
The materials which can be stamped are: low, medium & high
carbon steels, stainless steel.
This method is suitable for large volume production.
Stamped Gear
7. The metal powder is pressed in dies to convert into tooth shape,
after which the product is sintered. After sintering, the gear may
be coined to increase density & surface finish. This method is
usually used only for small gears.
Sintering Process
8. Blended Powder Compacted Rigid Tooling
( Powder compacted rigidly)
Pre-sinter
Repress or Coining Re-sinter Gear
Sintering Process
9. High quality gears can be made by powder metallurgy
method.
Gears made by powder metallurgy method find application in
toys, instruments, small motor drives etc.
Advantages
Accuracy similar to die cast gears
Material properties can be tailor made
Typically suited for small size gears
Economical for large lot size only
Secondary machining is not required
Applications
10. Injection Molding
Injection molding is used to make nonmetallic gears in
various thermoplastics such as nylon. These are low precision
gears in small sizes but have the advantages of low cost and
the ability to be run without lubricant at light loads.
Applications
Injection molded gears are used in cameras, projectors, wind
shield wipers, speedometer, lawn sprinklers, washing
machine
The materials for injection molding components are Nylon,
cellulose acetate, polystyrene, polyimide, phenolics.
Materials
11. Cold drawing forms teeth on steel rods by drawing them through
hardened dies. The cold working increases strength and reduces ductility.
The rods are then cut into usable lengths and machined for bores and
keyways, etc.
Cold Drawing
12. The steps in forging process are represented in fig and the
forged gears are shown in fig.
