Question

Manufacturing Technology

1. The effects of cutting fluids on biological considerations and the environment.

2. Find out method in face milling and end milling operation.
(i) procedure
(ii) application

3. Summarize the centerless grinding, cylindral grinding, surface grinding in 4 line.

4. What are the difference on the operation between sensitive drill press and radial drilling machine

Answer 1

Ans1 .
Four major concerns have been raised about the use
of metal working fluids.
1. particulates, tramp oils, and bacteria are known to reduce the quality of metalworking operations over time.
2. these contaminants eventually render the fluid ineffective for metalworking operations, creating significant acquisition and disposal costs that reduce profitability.
3. the disposal of Metal working fluid places a significant burden on the environment.
4. bacteria and the biocides used to control their growth in MWFs can be a sig nificant health hazard.

Ans2.

(i) . Face milling, in general, is defined as the process of cutting surfaces that are perpendicular to the cutter axis, or the faces of a part.

An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour. The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.

(ii). End mills are typically used in applications requiring profile milling, tracer milling, shape milling, face milling and plunging.

Face milling tools are used by themselves or in gang milling operations on manual horizontal or universal milling machines to machine large broad surfaces quickly
