This paper presents a research conducted in order to identify the cutting parameters effect on turning cutting forces and on the resulted machined surface quality for a CoCrWNi alloy. This alloy is a biomaterial used in medical applications for implants manufacturing. The main objective of the research is the development of prediction models for the turning cutting forces and the Ra roughness parameter for dry longitudinal turning with TiAlN PVD coated inserts. In order to achieve this objective, thirteen processing experiments were carried out, during which the cutting forces and roughness parameters were registered. The research results consist of the prediction models for cutting forces and Ra roughness parameter.
The process of the product design consists in a plan for the product, its components and subassemblies. To obtain the physical entity building a manufacturing plan is needed. The activity of developing such a manufacturing plan is name process planning. Process planning is the relation between design and manufacturing. Process planning consists in defining the sequence of the steps that should be taken to make the product. Process planning is referring to the engineering and technological issues of how to make it.
The paper presents a method for analysing the variance of manufacturing cost and price components using a scenario method. The analysis model is based on the usual relations for calculus of the total manufacturing cost and final price of the product, by integrating relationships that take into account complex dependencies between different components of a product cost and selling price.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
