MICROSTEREOLITHOGRAPHY

Anohter RP(rapid prototyping) approach, called microstereolithography, is based on stereolithography (STL), but the scale of the processing steps is reduced in size.Whereas the layer thickness in conventional stereolithography ranges between 75 qm and 500 qm, microstereolithography (MSTL) uses layer thicknesses between 10 to 20 qm typically , with even thinner layers possible.

PRODUCTION PLANNING

Production planning and control are the manufacturing support functions concerned with logistics problems in manufacturing.Production planning is concerned with planning what products are to be produced, in what quantities, and when.It also considers the resources requried to accomplish the plan.

SYNCHRONOUS SYSTEMS

In synchronous tranfer systems, work units are simultaneously moved between stations with a quick,discontinuous motion.these systems are also known by the name intermittent transfer,which characterizes the type of motion experienced by the work units.

Also called indexing, individual parts and components are supplied and assembled at a constant rate at fixed individul stations.The rate of movement is based on the station that takes the longest time to complete its portion of the assembly This system is used primarily for high-volume ,high speed assembly of small products.

MACHINING

Machinig is a manufacturing process in which a sharp cutting tool is used to cut away material to leave the desired part shape.
