The overall approach for the analysis of casting defects is illustrated below (Refer fig. 2). It is separated in two stages namely diagnosis and remedies. The approach starts with the detection of defects in casting components, followed by identification of their attributes and classification. The second stage involves determining the possible

Jul 03, 2018 · Step 1 – Identify the Defect Foundry personnel have a tendency to identify a defect based on cause like slag defect or sand inclusions. While this is an acceptable method, after the diagnosis is done, the International Atlas of Casting Defects recommends that unknown defects be classified based on appearance rather than cause.

Sushil kumar et al (2011) analyse casting defects and concluded that, the quality can be improved by Six Sigma i.e. (DMAIC) approach of parameters at the lowest possible cost. It is also possible to identify the optimum levels of signal factors at which, the noise factors effect on the response parameters is less.

Casting – Lost Wax Process The lost wax casting process is widely used as it offers asymmetrical casting with very fine details to be manufactured relatively inexpensively. The process involves producing a metal casting using a refractory mould made from a wax replica pattern. The steps involved in the process or the lost wax casting are:

Zero Defects (or ZD) was a management-led program to eliminate defects in industrial production that enjoyed brief popularity in American industry from 1964 to the early 1970s. Quality expert Philip Crosby later incorporated it into his "Absolutes of Quality Management" and it enjoyed a renaissance in the American automobile industry—as a performance goal more than as a program—in the 1990s.

The system used for classifying defects is based on a physical description of the defect under consideration; it is intended to permit an identification be made either by direct observation of the defective casting or from a precise description of the defect, involving only the criteria of shape, appearance, location and dimensions.

There are numerous opportunities for things to go wrong in a casting operation, resulting in quality defects in the cast product. In this section we compile a list of the common defects that occur in casting and we indicate the inspection procedures to detect them
knowledge about casting defect, their causes, and defect remedies one has to be analyze casting defects. Casting defect analysis is the process of finding root causes of occurrence of defects in the rejection of casting and taking necessary step to reduce the defects and to improve the casting yield.

So it is preferably necessary to reduce it as much as possible by appropriate analysis of the defects which includes the root cause analysis so that actual reasons behind occurring the defects can be found out to make the corrective action. In this work six sigma technique was used to identify and analyse casting defect.
