Modular cost model for Tolerance allocation, Process selection and Inspection planning

Fostering in-process inspection during process planning using tolerance charting

Integrated development of machining and inspection plans is essential in dynamic manufacturing environments, especially when right first time manufacturing is required. In this work, a methodology, based on a new and extended use of tolerance charting, that allows incorporation of in-process inspection operations to improve process plans is presented. The methodology proposes the transfer of th...

An integrated production-marketing planning model With Cubic production cost function and imperfect production process

The basic assumption in the traditional inventory model is that all outputs are perfect items. However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...

Automated Inspection Process Planning: Algorithmic Inspection Feature Recognition, and Inspection Case Representation for CBR

General metrological inspection planning is among the least explored CAPP domains. This paper explores certain basic issues involved in inspection planning using case-based reasoning in an environment of a Generic CAPP Support System. Firstly, algorithmic methods for characterizing and extracting inspection features are proposed and discussed. A sequential knowledge based filtering method is de...
