The
three methods
are; (1) visual inspection, (2) parts classification and coding, and (3) production flow analysis.
What are the methods of grouping parts into part families?
- by inspection,
- classification and coding, and.
- production flow analysis (PFA).
What are the parts of family?
Members of the immediate family may include
spouses, parents, grandparents, brothers, sisters, sons, and daughters
. Members of the extended family may include aunts, uncles, cousins, nephews, nieces, and siblings-in-law.
What is the need of grouping parts in part families?
Parts grouping in FMSs has advantages such as:
simplification of planning and scheduling, simplification of parts and tools flow
, reduction of setup costs, reduction of production costs, etc.
What do you mean by term part family explain methods of grouping part into families?
●
An approach to manufacturing in which similar parts are identified and grouped together in
.
order to take advantage of their similarities in design and production
.
What is a part family in CAD CAM?
Part Family is
nothing but a similar kind of properties like size, geometry etc
.. this is also considered the process of manufacturing if there is a similar sequence in producing a product or similar steps are used in it. then they all are made into a member of there part family.
What are the two types of parts similarities?
Two categories of part similarities can be distinguished:
(1) design attributes
, which arc concerned with part characteristics such as geometry, size, and material; and (2) manufacturing attributes, which consider the sequence of processing steps required to make a part.
What is Opitz classification system?
An Opitz code is
composed of 14 digits divided by three categories
. … Opitz code provides a basic framework for under- standing the classification and coding process. Further- more, it can be applied to machined parts, non-machined parts and purchased parts as it considers both design and manufacturing information.
Which is type of GT code?
A Group Technology(GT) code is
an alphanumeric string
which represents critical information about the product in a concise manner. Comparing the GT codes of two products is a quick and efficient method for estimating product similarity in selected attributes.
How the machine cells are classified?
An
18-digit
classification and coding method is developed. The first phase of the methodology enables the decision maker to assign priority to the attributes in order to group parts into part families. In the second phase, machines are grouped into manufacturing cells based on relevant operational costs.
Which layout is mostly used for batch type of production?
Process layout
What are the applications of group technology?
Group Technology (GT) as a manufacturing philosophy plays a major role in
design standardization, manufacturing cell layouts, process planning, purchasing, and manufacturing technology systems design
. One of the most effective ways to use GT is to facilitate significant reductions in design time and effort.
What is CAPP in Cam?
Computer-aided process planning
(CAPP) is the use of computer technology to aid in the process planning of a part or product, in manufacturing. CAPP is the link between CAD and CAM in that it provides for the planning of the process to be used in producing a designed part.
What is Dclass system?
DCLASS (
Design and Classification Information System
) was developed at Brigham Young University. The part code portion of this system was developed because no commercial vendor was willing to provide such a system for educational and research purposes.
What is the full form of Dclass system?
DCLASS (
Design and Classification Information System
) was developed at Brigham Young University. The part code portion of this system was developed because no commercial vendor was willing to provide such a system for educational and research purposes.
