Part program is the machine program that is written on medium losing a person, also can be to be what the computer prepares to lose a person, via machine program getting after processing. 32) machine program (MachineProgram) in processing control system automatically, the ordinal instruction part that writes by automata language and format. These dictate the record is on proper medium losing a person, can realize direct operation completely. 33) the program ends (EndofProgram) the auxiliary function that points out workpiece machines an end 34) data ends (EndofData) after all commands of block are carried out, make main shaft function and other function (cool for example function) the auxiliary function that all is deleted. 35) the program pauses (ProgromStop) after all commands of block are carried out, delete main shaft function and other function, stop ever since the auxiliary function of data processing. 36) prepare a function (PreparatoryFunctton) the command that makes machine tool or control system establish treatment function pattern. 37) auxiliary function (MiscellaneouSFunction) a kind of command of the switch function that controls machine tool or system. 38) cutting tool function (ToolFunetion) the format with corresponding basis is normative, identify or move person cutting tool. 39) feed function (FeedFunction) the command that defines standard of feed speed technology. 40) function of main shaft speed (SpindleSpeedFunction) the command that defines standard of technology of main shaft speed. 41) feed maintains (FeedHold) carry out in machine program period ask, interrupt the function of feed temporarily. 42) cutting tool contrail (ToolPath) the contrail that stipulates the dot has walked along on cutting cutting tool. 43) slanted at 0 o'clock buy (ZeroOffset) a kind of feature of numerical control system. It is concessional the origin that numerical control surveys a system is in appoint limits inside opposite at machine tool zero float, dan Jiyong is long in was being put in numerical control system at 0 o'clock. 44) cutting tool slants buy (ToolOffset) in a machine program all or designate a portion, the photograph counterpoint that brings to bear on to go up at machine tool reference axis moves. The displacement direction of this axis by slant buy is worth losing will decide.
45) cutting tool length slants buy (ToolLengthOffset) slant in what direction of cutting tool length predicts advance 46) cutting tool radius slants buy (ToolRadlusOffseO) cutting tool slants in the cutting tool of two coordinate direction buy. 47) cutting tool radius is compensated (CutterCompensation) the displacement that perpendicular Yu Dao provides orbit, the difference that uses the cutting tool radius that amends actual cutting tool radius and process designing 48) speed of feed of cutting tool contrail (ToolPathFeedrate) the datum mark on cutting tool moves at workpiece relatively along cutting tool contrail the speed when, its unit is used normally minutely or the mobile capacity that every turn will express. 49) fixed loop (FixedCycle, cannedCycle) beforehand the command of a few operations of set, according to these operations the command makes sleeve of machine tool coordinate moves, advocate sleeve works, complete fixed treatment action thereby.
