The Sawmill Improvement Program, better known as SIP, was launched in July of 1973 to help extend the Nation’s timber resources through more efficient sawmilling of logs. Administered by the U.S. Forest Service, the SIP increases a log’s breakdown efficiency and thereby helps sawmillers to recover more of their lumber. This means that more of the log resource becomes high-value lumber and less ...

the mean noise levels were measured in the different sections of six representative mills in the isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. the mean noise levels were on average 95 dba in the weaving sections and 88 d ba in the spinning sections. the audiometric findings showed a significant loss of gearing in the textile workers as compare...

failure in timber structures occurs mainly in crucial points such as joints areas. therefore, the idea of using composite sheets in timber joints has been intro-duced as a method in order to increase the strength and ductility behaviour of timber joints. this research aims to study the behaviour of bolted joints in poplar and pine woods, which are reinforced by two types of gfrp sheets. a singl...

The bark of logs from coniferous trees is mostly debarked in the stand or roadside. At terminal points, storages, and mills industrial debarking machines have been operated for timber, as well. In recent time chainsaw mounted apparatus (C-Debarker), axe, a new tool that brushcutter (B-Debarker) used peeling barks in-stand. Debarking process very time-consuming work phase within total unit wood ...

The implementation of condition monitoring tools can improve plant availability and lower downtime costs in general. A reliable adaptive control system prevent machine or undesired situations such as chatter vibration excessive tool wear, permitting the best utilization a tool's life. This study used dynamic force analysis to create an for Computer Numerical Control (CNC) milling adjust control...

In this study, the performances of end mills used widely in machining were investigated case their reuse by sharpening. For purpose, at CNC vertical center, slot milling processes carried out with HSS (used once) on AISI 1050 manufacturing steel having two different diameters and carbide (again D2 (2080) cold work tool diameters. Machining experiments made using four cutting speeds, feed depths...

 Introduction: Many items are needed for dressing including sterile dressing set, antiseptic and washing solutions, leucoplast tape, waste bin for infectious garbage, waste bin for noninfectious garbage, safe disposal trash for sharp cutting instruments, bedpan and sometimes drugs. All the items are laid out on a simple wheeled trolley. The multiplicity of items together with problems in placin...

The paper examines a new problem in the irregular packing literature that has existed in industry for decades; two-dimensional irregular (convex) bin packing with guillotine constraints. Due to the cutting process of certain materials, cuts are restricted to extend from one edge of the stock-sheet to another, called guillotine cutting. This constraint is common place in glass cutting and is an ...
