Off-Line Quality (new & better) (Quality Control)

Taguchi’s off-line quality control methods for product and process improvement have generated considerable industrial and academic interest. They emphasise designing quality ‘’into’’ products and processes, so that they are insensitive to sources of variability or noise, rather than achieving quality after the fact by on-line inspection. Parameter design, an important step in off-line quality control, is the search for levels of engineering parameters that lead to a product or process robust to the noise factors. These engineering parameters, such as nominal dimensions, are often called control factors, because they can easily be changed or controlled (unlike noise factors, which are typically expensive to control).

Off-line Quality (previous)

Off-line quality control activities conducted at the product and process design stages in the product development cycle.

On-Line Quality (new & better)  (Quality Control)

On line quality  control  may  refer  to  different  purposes:  the  first  one  is  to  follow  the  quality  of the final  product  according  to  time in order to  built  a  data  basis,  the  second  one  is  to  control  accurately each  process itself in  order  to  optimize  it and to made  the  equipment  self-running.

On-line Quality (previous)

 On-line quality control activities conducted at the manufacturing stage to keep the process in statistical control and to reduce manufacturing imperfections in the product.

Tool Allocation(new)  (Manufacturing Scheduling)

In flexible manufacturing system, tool allocation strategy which involves tool planning in the system and scheduling of parts and tools can strongly affect the system efficiency. Considering the basic flows in FMS, a part-centric tool allocation strategy and a tool-centric tool allocation strategy are purposed. Generally, the part-centric allocation strategy involves few tool movements and the tool-centric allocation strategy involves few part movements.

Tool Allocation (previous & better)

 The operational capabilities of an advanced CNC machine are determined and/or constrained to a great degree by the set of cutting-tools assigned to the machine. Maximizing the operational flexibility of a machining center would be easy is each machine had a tool magazine of infinite (or very large) size. This would enable each machine to be loaded with all the different types of tools available in the tool crib. However, this option is not economically viable, since it would require a very high investment in cutting tools. In addition, the average utilization of cutting-tools in the system would be poor. In practice, therefore, cutting-tool magazines at machines are of limited size, typically having capacity of 20 to 60 tools.
