In 25 digital control processing subroutines listing at table 1, a lot of digital control processing subroutines can only be processed the very short time.Therefore necessary Attended mode, often process a digital control processing subroutine, just need to call in next digital control processing subroutine by the manual input of guidance panel instruction, if cutter or accessory head difference that next digital control processing subroutine is used, that also needs manual input instruction, change accessory head, change cutter, survey cutter and grow and compensate, then could carry out and newly call in digital control processing subroutine and process.
For example, shown in table 1, first digital control processing subroutine is SMNLC63, and the cutter of its use is φ 63R8, and processing content is the thick material of taking, and processing duration is 11 points 56 seconds (11:56).Shown in table 1, second digital control processing subroutine is SMZC32, and the cutter of its use is S φ 32, and processing content is roughing again, and processing duration is 35 seconds (0:35).Be understandable that, in order to reduce follow-up work, advantageously, in the time that digital control processing subroutine is provided, provide the sequence number (showing the sequencing of processing) of each digital control processing subroutine, the accessory head adopting and the cutter of employing simultaneously.
Described routine processes step mainly comprises following three steps: steps A, step B and step C.
Steps A is subroutine call step, comprises following content: a master routine is provided, calls in order described multiple digital control processing subroutine in described master routine.The system that concrete call instruction can adopt according to concrete numerically-controlled machine is determined.As, the instruction of calling first digital control processing subroutine SMNLC63 is CALL SMNLC63; The instruction of calling second digital control processing subroutine SMZC32 is CALL SMZC32.The like.The master routine obtaining is thus as follows:
CALL SMNLC63 (calling the 1st digital control processing subroutine)
CALL SMZC32 (calling the 2nd digital control processing subroutine)
……
CALL SMHHJQ4 (calling the 25th, i.e. last digital control processing subroutine)
In order to increase intuitive and to reduce mistake, each digital control processing subroutine can also be named according to processing sequence.For example,, by first digital control processing subroutine SMNLC63 called after 0001(or 1,01,001,00001; Or the appropriate ways such as P1, P01, P001, P0001, P00001 even); By the instruction called after 0002(or 2,02,002,00002 of second digital control processing subroutine SMZC32; Or the appropriate ways such as P2, P02, P002, P0002, P00002 even).The like.The master routine obtaining is thus as follows:
CALL 0001 (calling the 1st digital control processing subroutine)
CALL 0002 (calling the 2nd digital control processing subroutine)
……
CALL 0025 (calling the 25th, i.e. last digital control processing subroutine)
Step B changes accessory head subroutine procedure for calling, comprise following content: judge whether two adjacent digital control processing subroutines use different accessory heads, if, calling between the instruction of adjacent described two digital control processing subroutines, inserting and call the instruction of changing accessory head subroutine.
Suppose that first digital control processing subroutine SMNLC63 and second digital control processing subroutine SMZC32 use maybe can be used same accessory head.In the case, call without insertion the instruction of changing accessory head subroutine.Next, can judge that whether second subroutine be identical with the 3rd accessory head that subroutine is used, the like.

Also it is to be noted, judge whether first digital control processing subroutine SMNLC63 and second digital control processing subroutine SMZC32 use same accessory head, can after calling all 25 digital control processing subroutines, carry out, also can carry out calling after second digital control processing subroutine.That is to say, step B can intersect and carry out with steps A above.
Step C changes cutter subroutine procedure for calling, comprise following content: judge whether two adjacent digital control processing subroutines use different cutters, if so, calling between the instruction of adjacent described two digital control processing subroutines, inserting and call the instruction of changing cutter subroutine.
For example, from table 1, first digital control processing subroutine SMNLC63 and second digital control processing subroutine SMZC32 use different cutters, call thereby need to insert the instruction of changing cutter subroutine between the instruction of master routine " CALL0001 " and " CALL0002 ", for example, insert " CALL tool changing S φ 32 ".The master routine obtaining is thus as follows:
CALL 0001 (calling the 1st digital control processing subroutine) CALL tool changing S φ 32 (call and change cutter subroutine)
CALL 0002 (calling the 1st digital control processing subroutine)
……
CALL 0025 (calling the 25th, i.e. last digital control processing subroutine)
The like, after all digital control processing subroutines are processed, can obtain a master routine, all digital control processing subroutines are connected into a program by this master routine.Thereby, multiple digital control processing subroutines can be linked together and automatically carry out, thereby greatly improve the automaticity of digital control processing, improve working (machining) efficiency.For example, can realize in whole NC Machining Process that unmanned or a people are on duty keeps an eye on many lathes.
