What is Opitz coding system?

Optiz is a coding system that used to identify the products Dimensions, Accuracy, Material, Original shape of raw material etc. To identifying the complete information related to product from raw material to manufacturing it includes many steps like design, cutting, finishing etc. …

Which are types of codes in Opitz system?

An Opitz code is composed of 14 digits divided by three categories. The first category, 1st to 5th digit, is called “form code” dedicated for design attributes includ- ing gemetrical and topological information (Fig 2). The second category from 6th to 10th digit is supplementary code used for manufacturing attributes.

How Group technology will be implemented in a system?

One vehicle for implementing GT is classification and coding (CC), a methodology which organizes similar entities into groups (classification) and then assigns a symbolic code to these entities (coding) in order to facilitate information retrieval. CC is typically viewed as a computer-based technology .

Which code is used in group technology?

The plan for processing each component is coded into OP codes (operation codes). Each OP code represents a set of machining operations. Thus the complete plan of a part is represented by means of a sequence of OP codes.

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 basis for forming groups in group technology?

Group technology is based on a general principle that many problems are similar and by grouping similar problems, a single solution can be found to a set of problems, thus saving time and effort. …

What is Group Technology discuss in details?

Group technology is an approach in which similar parts are identified and grouped together in order to take advantage of the similarities in design and production. Similarities among parts permit them to be classified into part families. The advantage of GT can be divided into three groups: Engineering.

What are the pros and cons of group technology?

Short throughput times because machines are closed together. Better quality because groups complete parts and the machines are closed together under one foreman. Lower material handling costs because machines are closed together under one foreman. Better accountability because of machines complete parts.

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 are the benefits of Group Technology?

Advantages of Group Technology: (i) Better lead times result in fast response and more reliable delivery. (ii) Material handling is reduced considerably. (iii) Robots can be easily used for material handling. (iv) Better space utilisation.

What is the objective of Group Technology?

Group technology is drawing increasing interest from manufacturers because of its many applications for boosting productivity. GT is an approach to manufacturing that seeks to maximize production efficiencies by grouping similar and recurring problems or tasks.

What is the role of GT in CAD CAM?

GT helps to simplify process planning and thus forms as a bridge between CAD and CAM in the form of CAPP. GT is a manufacturing technique in which part having similarity according to size, shape, or nearly equal tomanufacturing process are grouped together to increase productivity and reduce lead time……..
