1、Designation:D667208Standard Practice forFormatting Cutting Data to Drive Numerically ControlledFabric Cutting Machines1This standard is issued under the fixed designation D6672;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year
2、 of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice specifies a data format for numerically-controlled cutting machines for fabric.1.2 This standard uses a s
3、ubset of the defined instruction setdefined inANSI/EIA-274-D in addition to the codes defined bythis practice.1.3 This practice does not support curve interpolation ordefinitions.All curves are represented by discrete vectors(stroked)and are dependent on the resolution of the CADsoftware.1.4 This pr
4、actice requires that all coordinates are absolute,not relative.1.5 This practice only supports positive coordinates that aremeasured from a single X-Y origin point with coordinates(0,0).The origin point is specified as the lower left corner ofthe cut file.1.6 This practice intends to transfer a stat
5、ic image with noprovision for editing.1.7 This practice imposes no limits on the width or length ofthe cut data.Physical limitations imposed by the hardware andtheir effects on the output are the responsibility of the hardwaremanufacturer.1.8 This practice does not support bite commands or anymethod
6、s that insert multiple origin points or floating coordinatesystems.1.9 This practice does not support notch tools.1.10 This practice does not support pattern matching.1.11 This practice limits the cut file to contain a single blockof data demarked by a compatible header and terminator.Multiple block
7、s of data in a single file are not allowed.1.12 Any commands found in the cut file that are notdefined by this standard shall be ignored.1.13 The intended application of this practice is limited tothe class of output devices found in the sewn product industriesthat produce apparel,textiles,upholster
8、y,and others that usesoft or semi-rigid materials.1.14 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of reg
