this study examines inventory management practices of flour milling manufacturing firms and their effects on operational performance. five flour milling manufacturing firms in lagos were used for this study. structured questionnaire was the major instrument for the collection of relevant primary data while descriptive statistics such as mean and standard deviation was deployed to analyzing the ...

Abstract: Plain Milling is one of the progressive enhancements of miniaturized technologies which have wide range of application in industries and other related areas. Plain milling cutters are widely used in roughing and finishing of parts. The milling cutter geometry and distribution of inserts on the cutter body vary significantly in industry depending on the application. This paper presents...

Mintek, specialists in mineral and metallurgical technology, have developed advanced optimisation control strategies in milling, flotation and smelting. The strategies address process specific problems namely downstream flow disturbances in flotation circuits from open milling circuits, fluctuating grade and recovery of flotation circuits and furnace fault conditions including power trips and e...

GQM+Strategies is an approach that aligns the business goals at each level of an organization to strategies to achieve overall business goals and assesses the achievement of such goals. Strategies are extracted from business goals based on rationales (contexts and assumptions). Using the proposed approach, which refines the GQM+Strategies model by extracting rationales based on the analysis of ...

Computer-Aided Manufacturing (CAM) occupies an increasingly important role in engineering with all it has to offer in terms of new possibilities and improving designer/manufacturer productivity. The present study addresses machining of free-form surfaces on a 3-axis NCmachine tool. There have recently been a large number of studies devoted to planning tool paths on free-form surfaceswith variou...

In this study the effects of machining parameters such as shearing speed, feed rate, tool diameter and machining depth on different milling strategies i.e. 3D offset, spiral, raster and radial to produce the convex surface made of epoxy/glass composites is investigated. The effects of mentioned strategies on output parameters such as surface roughness and milling removal rate is also studied. T...

Along with technological progress, manufacturing processes have been constantly innovated, hoping to reduce time, extend the useful life of tools and offer high quality finishes product, however, information on product is scarce. Machined in 7075 - T6 aluminum, which, due its mechanical properties, more used for manufacture molds dies than other materials. In this project, a high-performance ma...

In waterjet and laser milling, material is removed from a solid surface in a succession of layers to create a new shape, in a depth-controlled manner. The inverse problem consists of defining the control parameters, in particular, the two-dimensional beam path, to arrive at a prescribed freeform surface. Waterjet milling (WJM) and pulsed laser ablation (PLA) are studied in this paper, since a g...
