Work Cell – Realization of a Lean Process •A work cell's effectiveness is not separable from related elements: - The product(s) - Workers must be able to manufacture and assemble the product to meet customer demand [DFA, DFM] - A breadth of products often must be accommodated by a single
Face milling is the most common milling operation and can be performed using a wide range of different tools. Cutters with a 45º entering angle are most frequently used, but round insert cutters, square shoulder cutters and side and face mills are also used for certain conditions. Be sure to choose the right cutter for the operation for ...
Definition Of Milling : Milling is a process performed with a machine in which the cutters rotate to remove the material from the work piece present in the direction of the angle with the tool axis. With the help of the milling machines one can perform many operations and functions starting from small objects to …
• Cutting tools may be classified according to the number of major cutting edges (points) involved as follows: – Single point: e.g., turning tools, shaping, planning and slotting tools and – boring tools – Double (two) point: e.g., drills – Multipoint (more than two): e.g., milling cutters, broaching tools, hobs, – …

Cutting as a mechanical process is the removal of material resulting through use of force, typically shear and compressive. Although "cutting" is certainly a cutting process, grinding, milling, and drilling are also cutting processes as they result in material removal through the application of appropriate forces.

A Different Approach to Presentation Design. We subscribe to the less is more school of thought. Evey slide we design for you needs to earn it's place in your presentation. When we put your content together, we will go through it with a fine tooth comb and ruthlessly remove any elements that do not need to be there.
The purpose of this booklet is to set out the basic design for an industrial gearbox. It should help students not familiar with gearboxes, lay out a reliable working design. And it is intended for the reader to use his own experience in selecting formulae, stress values etc., for gearbox components.

Jig Design Guidelines Make all component clamping devices as quick acting as possible. Design the jig fool-proof by the use of foul pins and similar devices, that is arrange it so that the component, tools or bushes cannot be inserted except in the correct way. Make some locating points adjustable when the component is a rough casting and may
