Analyzing Investments in Thin-kerf Saws
نویسندگان
چکیده
The rising cost of hardwood sawlogs has increased sawmill managers’ interest in considering the installation of thin-kerf sawing machines in their sawmills. Replacement of circular headrigs by band headrigs and/or reducing resaw kerfs are the available options. Equipment replacement or modification to achieve thin-kerf sawing will require an investment. Sawmill managers making such an investment will desire to reduce risk by determining the probable investment outcome. Determining the probable outcome with some certainty can require a complex analysis. The staffs of many sawmill firms don't possess all the required information to perform such a complex analysis. One option for them is to turn to a consultant with the required skills. However, a preliminary analysis to determine the relative potential for the investment will help sawmill managers determine whether employing a consultant would be worthwhile.

Statistical analysis of kerf mark measurements in bone
Saw marks on bone have been routinely reported in dismemberment cases. When saw blade teeth contact bone and the bone is not completely sawed into two parts, bone fragments are removed forming a channel or kerf. Therefore, kerf width can approximate the thickness of the saw blade. The purpose of this study is to evaluate 100 saw kerf widths in bone produced by ten saw types to determine if a sa...
متن کاملPractical Alignment Tools and Techniques
Accurate sawing requires attention to proper alignment and maintenance. Alignment is critical to modern sawmills using thin kerf saws. In fact, the improvements in machine design were critical to the development of thin kerf sawing systems. About two-thirds of sawing problems are caused by misalignment, not saw preparation. Good alignment reduces down-time and machinery wear and should be part ...

Laser beam machining (LBM) is one of the most widely used thermal energy based non-contact type advance machining process. In recent years, researchers have explored a number of ways to improve the LBM process performance by analyzing different factors that affect the quality characteristics of LBM process such as kerf width, kerf taper, surface finish etc. It is revealed from the literature th...
متن کاملMass sensitivity of dual mode SAW delay lines on AlN=sapphire structure
Introduction: There have been growing demands in recent years for highly sensitive surface acoustic wave (SAW) sensors that are able to detect minute quantities, especially in the chemical and biological fields. AlN is a promising material to fulfil such a task because of its high SAW velocity and good piezoelectricity [1]. Compared to conventional bulk piezoelectric materials such as quartz an...
