Current state and development possibilities of wood chip supply chains in Austria
Nacrtak The importance of forest wood chips as fuel for energy production will increase relative to sawmill by-products. The additional production is not a question of potential (harvesting residues, wood from thinning, coppice stands and short rotation forests) but more so a question of economic feasibility. The analyses of different chip production systems resulted in the identification of tw...
متن کاملA Key to the Utilization of the Total Tree
to resaws. As the chipping headrig operator adjusts the cutterheads for a really ~lose shave, the rounded surface of the log is chipped away, leaving a log-length square timber. The whiskers are the chips. Instead of ntaking sawdust as conventional sawing techniques would, the chipping headrig makes chips, a valuable commodity to anyone who happens to own a paper mill. The chipping headrig kiss...
متن کاملSmoothing a rock by chipping.
We investigate an idealized model for the size reduction and smoothing of a polygonal rock due to repeated chipping at corners. Each chip is sufficiently small so that only a single corner and a fraction of its two adjacent sides are cut from the object in a single chipping event. After many chips have been cut away, the resulting shape of the rock is generally anisotropic, with facet lengths a...
متن کاملEvaluation of Chipping Productivity with Five Different Mobile Chippers at Different Forest Sites by a Stochastic Model
It is important to evaluate chipping productivity that often differed according to the timing of observations and varied unexpectedly. A variation in production was the major concern of stakeholders for sustainable forest operation to establish regularly attainable production schedules on many operational levels. The aim of this study was to estimate the variance of chipping productivity by usi...
متن کاملAn Experimental Investigation on Surface Roughness and Edge Chipping in Micro Ultrasonic Machining
Surface quality including surface roughness and edge chipping is a key process measure in micro ultrasonic machining (Micro-USM) as an efficient process for micromachining of hard and brittle materials. Process parameters such as ultrasonic vibration amplitude, static load, type of tool material, type and size of abrasive particles and slurry concentration can influence the surface quality. How...
