Three Automation Types
A. Fixed Motorisation
A system in which the sequence of processing (or assembly) businesses is set by the tools configuration. The operations in the sequence are usually simple. lt is the incorporation and skill of many this sort of operations into one piece of equipment that makes the system complicated.
Suited to high production amounts
High primary investment to get custom-engineered equipment
High creation rates
Relatively inflexible in accommodating product variety
The economic justification for set automation is found in products with very high demand rates and volumes. The high initial cost of the device can be spread over a very many units, hence making the machine cost attractive compared to substitute methods of development. Examples of fixed automation include mechanized set up lines (starting around 1913 - the merchandise moved along mechanized conveyors, but the work stations along the collection were physically operated) and machining transfer lines (beginning around 1924).
B. Pre-reglable Automation
The production equipment is built with the capability to modify the pattern of operations through reprogramming to accommodate distinct product constructions. The procedure sequence is controlled with a program, which is a set of guidelines coded in order that the system can see and translate them. New programs may be prepared and entered into the device to produce new releases.
High expense in programmable equipment
Lower production prices than fixed automation
Overall flexibility to deal with variants and changes in product setup Most suitable to get batch development
Physical installation and component program must be changed between jobs (batches)
Automated development systems which can be programmable are being used in low and medium-volume production. The parts or perhaps products are normally made in batches. To produce every new batch of a distinct product, the program must be reprogrammed with the pair of machine guidance that correspond to the new merchandise. The physical setup in the machine should also be transformed over: Tools must be packed, fixtures has to be attached to the device table, plus the required machine settings should be entered. This kind of changeover treatment takes time. Therefore, the typical pattern for a provided product has a period during which the create and reprogramming takes place, followed by a period in which the batch can be produced. Samples of programmable automation include numerically controlled equipment tools (first prototype exhibited in 1952) and commercial robots (initial applications about 1961), although the technology offers its origins in the Jacquard loom (1801).
C. Versatile Automation
The machine is capable of fixing over from a single job to the next with small lost time between jobs. Flexible automation is an extension of programmable motorisation. The concept of adaptable automation is rolling out only over the last 15 or 20 years, plus the principles remain evolving. A versatile automated system is one that has the ability to of producing various products (or parts) with virtually no time misplaced for changeovers from one merchandise to the next. There is not any production time lost while reprogramming the machine and modifying the physical setup (tooling, fixtures, equipment settings). Therefore, the system will produce various combinations and activities of products, instead of requiring that they can be made in separate batches.
High investment for custom-engineered system
Ongoing production of variable integrates of products
Channel production costs
Flexibility to manage soft merchandise variety
The primary features that distinguish flexible automation from programmable motorisation are: (1) the capacity to modify part applications with no shed production time, and (2) the capability to improve over the physical setup, again with no shed production time. These...
