3、.Different species and products,however,vary greatly in theirbehavior under cutting tools,so that some systematic method is needed for determining theirsuitability for uses where the character of the machined surface is of prime importance.Such usesinclude cabinetwork,millwork,and other applications
4、 where favorable machining properties areessential to good finish.For such products as common boards,on the other hand,good machiningproperties are secondary,although still an asset.The machining test procedures presented in these test methods cover such common operations asplaning,routing/shaping,t
5、urning,boring,mortising,and sanding.They are the result of many yearsof extensive research and development and include practical methods for qualitatively evaluating andinterpreting the results.Because of their satisfactory use with a wide range of materials,it is believedthat the methods are equall
6、y applicable to all species of hardwoods and softwoods,and to wood-basepanel materials,such as plywood,particleboard,fiberboard,and hardboard.1.Scope1.1 These test methods cover procedures for planing,routing/shaping,turning,mortising,boring,and sanding,all ofwhich are common wood-working operations
7、 used in themanufacture of wood products.These tests apply,in differentdegrees,to two general classes of materials:1.1.1 Wood in the form of lumber,and1.1.2 Wood-base panel materials such as plywood andwood-base fiber and particle panels.1.2 Because of the importance of planing,some of thevariables
8、that affect the results of this operation are exploredwith a view to determining optimum conditions.In most of theother tests,however,it is necessary to limit the work to one setof fairly typical commercial conditions in which all thedifferent woods are treated alike.1.3 Several factors enter into a
9、ny complete appraisal of themachining properties of a given wood or wood-base panel.Quality of finished surface is recommended as the basis forevaluation of machining properties.Rate of dulling of cuttingtools and power consumed in cutting are also importantconsiderations but are beyond the scope of
10、 these test methods.1.4 Although the methods presented include the results ofprogressive developments in the evaluation of machiningproperties,further improvements are anticipated.For example,by present procedures,quality of the finished surface isevaluated by visual inspection,but as new mechanical
11、 orphysical techniques become available that will afford improvedprecision of evaluation,they should be employed.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand a
