章節(jié)摘錄

　　For machines that have the ability to perform operations with several tools， there are fourkinds of program format： program start-up format， tool ending format， tool start-up format， andprogram ending format. The programmer will begin every program with program start-up format.At the completion of program start-up format， the tool will be ready to begin cutting. At this point，the programmer will program the cutting operations with the first tool. When finished cutting， theprogrammer will follow the format to end the tool （tool ending format）. Then tool start-up format tobegin the second tool. The programmer will then toggle among cutting information， tool endingformat and tool start-up format until the finished cutting with the last tool. At this point， theprogrammer will follow the format to end the program.　　For an example ofthe four kinds of program format， refer to the program given during ourdiscussion of tool length compensation in Unit 6. This program uses two tools and follows the strictformat we are now discussing. Lets determine what commands are related to each kind of format.　　The first four commands （beginning with the program number） make up the program start-upformat. At the completion of line N015， the tool is ready to begin machining. Lines N020 and N025make up the cutting commands for the first tool. （In line N020， the feedrate should be consideredpart of program start-up format.） Lines N030 and N035 form the tool ending format. Lines N040through N055 are tool startup format. （In line N060， the feedrate should be considered part of toolstartup format.） Lines N060 and N065 are the cutting commands for the second tool. And linesN070 and N075 are program ending format.　　By breaking up the program in this manner， you should be able to see just how much of theprogram is nothing more than program format that can be copied from one program to another6. Ofcourse， certain word values like spindle speeds， feedrates， axis positions， and tool station and offsetnumbers will change based on the program you are currently writing. But the basic structure can becopied， keeping you from leaving out important information. Note that there are only fourcommands that do any cutting in this program. The bulk of the program is just format.　　How you come up with program format information for your machine　　The best way is to take an example program that is currently running successfully and break itup in the manner shown above. When doing this， analyze just what each tool is doing to determinethe various types of format7. Ensure that each tool contains all information needed to runindependently.
