assessments are then integrated into a sustainable manufacturing assessment framework‚ along with a modified weighting method based on pairwise comparison and an outranking decision making method. The approach is illustrated for a representative machining work cell producing stainless steel knives. Economic‚ environmental‚ and social impact results are compared for three production scenarios by applying the sustainable manufacturing assessment framework. Sensitivity analysis is conducted to study

An experiment was conducted to evaluate the biodegradability and the toxicity of vegetable oils in comparison with the reference mineral-based oils. In the research paper produce by Tamada et al. (2012)‚ carried out an investigation on the biodegradability of vegetable oils and the impact of toxicity of vegetable oils to the environment. The experiment was first started off‚ by establishing the concentration of oil to be biodegraded in the soil for the toxicity test. The concentration of oils that

Non-Tradional Machining What is the principal cause of tool wear in ECM? There is no tool wear to speak of in ECM as the tool is protected cathodically during the process. There may be some chemical reaction between the tool and the electrolyte when the power is off‚ depending upon the materials involved. What is the nature of the surface obtained by electro discharge machining? The surface is heated by the sparks to either melt or even vaporize metal. The melted metal is washed away

A grinding machine‚ often shortened to grinder‚ is any of various power tools or machine tools used for grinding‚ which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel’s surface cuts a small chip from the workpiece via shear deformation. Grinding is used to finish workpieces that must show high surface quality (e.g.‚ low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is on the order

The two lines are both mechanically complex‚ and require machining‚ assembly and inspection. Stanley receives raw materials to be used in the production of these two items‚ and uses a First-In‚ First-Out inventory system. They are currently using a traditional costing method for the two products‚ which applies

It uses a job-costing system with two direct-cost categories (direct materials and direct labor) and one indirect-cost pool (assembly support). Direct labor-hours is the allocation base for assembly support costs. In December 2010‚ Amesbury budgets 2011 assembly-support costs to be $8‚300‚000 and 2011 direct labor-hours to be 166‚000.

Rochester Manufacturing Corporation (RMC) is considering moving some of its production from traditionally numerically control machines to a flexible machining system (FMS). Its numerical control machines have Machine utilization‚ as near as it can be determine‚ and are about 10%. The machine tool sales persons and a consulting firm want to put the machines together in a FMS. They believe that a $3‚000‚000.00 expenditure on machinery and the transfer machines will handle about 30% of RMC s work. There

1.0 BACKGROUND OF THE COMPANY This report is basically consists of the details of the company that we managed to visit‚ AJ Food Industries. It’s focusing on the product costing which is how the company compute its unit costs in determining the proper amount of overhead cost. We proposed the company to use Activity-Based Costing which is multiple bases in considering the overhead cost. Its an advantage for the company that involved with complex manufacturing process. In this study‚ we take mayonnaise
