The most emerging needs of the modern metal cutting operation are to increase the material removal rate with better surface finish and high machining accuracy. These objectives can be achieved by reducing cutting temperature in the cutting zone. In metal cutting process, high cutting temperature and its detrimental effects are generally reduced by proper selection of process parameters, proper ...

Immersive virtual environments (IVEs) allow individuals to see, hear, and feel digital stimuli as if they were in the physical world. Two studies tested the power of embodied experiences within IVEs by comparing the effects of cutting a virtual tree against reading a print description or watching a video depiction of the tree-cutting process to encourage paper conservation. Experiment 1 found t...

In this paper, we investigate the use of Gomory's mixed integer cuts within a branch-and-cut framework. It has been argued in the literature that \a marriage of classical cutting planes and tree search is out of the question as far as the solution of large-scale combinatorial optimization problems is concerned" 16] because the cuts generated at one node of the search tree need not be valid at o...

iron wood (parrotia persica) tree as a forest species has many applications in urban green landscape. however, its reproduction and seedling production have not been studied in iran. thus, knowing the type of cutting and hormone treatments to increase the rooting of cuttings can be very effective. accordingly, annual and perennial cuttings were prepared in january and june, respectively. cuttin...

ARTICLE INFO Tool wear and tool life are the principle areas are focus in any machining activity, the production rate, surface finish of the machined component and the service life of machine are directly related to the defects in the tool. Vibration signals and expert system like decision tree algorithm can be used to prevent the damage on cutting tools and work pieces when the defect in the t...

Competition for land use between forestry and reindeer husbandry has been debated in northern Finland, particularly due to the possible adverse effects of on availability forage resources reindeer. In an attempt achieve a better reconciliation these uses, as well promote multiple forest use, we studied 37 stand-, plot-, tree-level variables pendulous lichens (Alectoria sp., Bryoria sp. Usnea sp...

This work proposes a process planning for machining of a Floor which is the most prominent elemental machining feature in a 21⁄2D pocket. Traditionally, the process planning of 21⁄2D pocket machining is posed as stand-alone problem involving either tool selection, tool path generation or machining parameter selection, resulting in sub-optimal plans. For this reason, the tool path generation and...

Abstract The Cutting Methods Study at the Ford Forest in Upper Peninsula of Michigan, USA, was established 1956 and has been maintained continuously on a 10-year cycle. consist three diameter limits (DL; 13, 30, 41 cm), single-tree selection to residual basal area (STS; 11, 16, 21 m2ha−1), light improvement (LI) focused improving tree grade. Long-term results show that cm DL produced greatest m...

The capacity of rainforests to recover from logging disturbance is difficult to model due to the compounding interactions between long-term disturbance effects, natural dynamics, site characteristics and tree species regeneration strategies. The aim of this study was to develop a quantitative model using over three decades of data from stands subjected to various levels of disturbance ranging f...
