Rough machining that particularly is applicable to the male contact with the hollow standard

In accordance the spare parts and guides that and the thinking of check adjust the removing suppling the largesttest degree control of cutting tool
EDSUnigraphics still consists of greats quantity else the respects meritorous service capacitys , and did not enumerate one by one here
STRATA's process means is analysed
STRATA is a digital control programming system development environment , and it is establishing ACIS's geometry model building terrace on
It supplys two kinds of programming development environments in the interest of consumer , in immediate future NC's command language interface and the NC's operation C++ storehouse . It may back three to mill , and turning and string cut NC and process , and may back wire frame , camber and the entity geometry model building . Such NC's cutting tool locus formation means is baseding on the physical model . STRATA is baseded on , and what supplys the process means in entity NC's cutting tool locus formation type storehouse consists of :
ProfileToolpath: Rough sketch process
AreaClearToolpath: The area on plane processes
SolidProfileToolpath: The entity rough sketch is processed
SolidAreaClearToolpath: The area on entity plane processes
SolidFaceToolPath: The entity face processes
SolidSliceToolPath: The entity severs process on plane
LanguagebasedToolpath: Baseding on , language cutting tool locus generates
Else CAD/CAM software , in case Euclid the person who awaits the NC's meritorous service capacity is each has his strong point , yet such fundamental substance is almost alike , the not natural difference .
2.4 main problem of systematic sword track formation means of active duty CAM
In accordance tradition CAD/CAM's system and CNC's system work means , CAM's system is with directly either the indirect means gains the produce geometry data model through CAD's system ( by means of neutral papers ) . CAM's system is with spot , string , surface in the three dimensions geometrics model and either the entity is the drive target , the cutting tool locus is processed in the formation , and afterwards the shape with the cutting tool locating file viaes the handle is placed , with the NC's code shape supplys to CNC's machine tool , the some respects problems under being living in entire CAD/CAM and the CNC's system operation process to be :
CAM systematically can only gain produce low tier of geometry message through CAD's system , and can not seize voluntarily meritorous service capacity and the semantic information of produce geometry shape information and produce higher level .
Hence manufacturing engineering master that entire CAM's process have to be living is very experience haves a hand in secondly , and completees mutually by means of the figure .
In case : Manufacturing engineering master .
The entire system automation degree is leted drop
Being living in the CAM's system generation cutting tool locus , equal also merely embodying low straturm geometry message ( right line and arc geometry locating information ) , along with the a little process control information ( as moving forward ) to rate , main shaft rotation speed and trading sword and so on .
Hence , can not obtain the process technology parameter that haves something to do with against generateing the cutting tool locus yet
The produce data between CAM's system every module are not unitied , and the independence is opposite to each other to every module . 数控加工技术英文文献和中文翻译(5):http://www.youerw.com/fanyi/lunwen_78433.html
