17、TD*ISO 3572-ENGL 2000 L. 4853703 0844853 b37 IS0 3592:2000(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical comm
18、ittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the
19、International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member
20、 bodies for voting. Publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. IS0 shall not be held responsible fo
21、r identifying any or all such patent rights. International Standard IS0 3592 was prepared by Technical Committee ISOTTC 184, Industrial automation systems and integration, Subcommittee SC 1, Physical device control. This second edition cancels and replaces the first edition (IS0 3592:1978), which ha
22、s been technically revised. Annexes A and B form a normative part of this International Standard. O IS0 2000 - Ail rights reserved V STD-ISO 3592-ENGL 2000 .I 4853903 0844852 573 = IS0 3592:2000(E) Introduction The output of a general purpose numerical control processor is information used as input
23、to a post processor. This information is called CLDATA, which was originally derived from “cutter location data.” CLDATA provides a general language to pass manufacturing information from a numerical control processor to a post processor, where the general language is converted to the specific forma
24、t required by the particular numerical control equip- ment. Numerical control is applied to many types of machines, but the language defined in this International Standard has been developed primarily for numerically control- led machine tools - hence the words “tool” and “part” are used in the desc
25、ription of the language to indicate the working element and processed element respectively. Many of the vocabulary words are also derived from metal working terminology. The CLDATA reference language (RL) is stream oriented, containing special characters to delimit the elements of the RL. Annex A de
26、scribes the rules for representing the RL on record oriented media, and it is this representation that is used for the purpose of describing the RL in this International Standard. vi O IS0 2000 -All rights reserved INTERNATIONAL STANDARD IS0 3592:2000(E) Industrial automation systems - Numerical con
27、trol of machines - NC processor output - File structure and language format 1 scope This International Standard defines a file structure format and a language format for the representation of CLDATA on physical media. The CLDATA reference language (RL) is used for the machining of parts. It provides
28、 for the control of technologi- cal functions and movement at the numerical control ma- chine. Each processor using one of the numerical control pro- gramming languages shall be capable of producing CLDATA as defined in this International Standard. Each post processor shall be capable of using the C
29、LDATA defined in this International Standard as input. The RL has been developed primarily for numerically controlled machine tools. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard
30、. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below
31、. For undated references, the latest edition of the normative documents referred to applies. Members of IS0 and IEC maintain registers of currently valid International Standards.

33、rdinate system IS0 841 is the basis for defining the co-ordinate system of CLDATA. The co-ordinate system is a right-handed rectangular Cartesian system, related to a part mounted on a machine and aligned with the principal linear slideways of that machine. The positive direction of movement of a co
34、mpo- nent of a machine is that which causes an increasing positive dimension on the part. In the CLDATA, the reference axes of the co-ordinate system are x, y and z. Co-ordinates refer to a reference point on a tool (usually the center of the tip) relative to the part co-ordinate system. CLDATA can
35、define the following location and orientation components: x Dimension parallel to X y Dimension parallel to Y z Dimension parallel to Z i X axis component of the tool axis vector j Y axis component of the tool axis vector k Z axis component of the toot axis vector l X axis component of a secondary o
36、rientation vector rn Y axis component of a secondary orientation vector n Z axis component of a secondary orientation vector When specifying angles of planes, the positive direction is counterclockwise and the reference axis is as shown in table 1. The positive direction of angle is counterclockwise
37、 from the reference axis. Table 1 - Reference axes I Plane I Reference axis i Angles are expressed in degrees and decimal fractions of a degree. 4 General structure of CLDATA CLDATA consists of a sequence of one or more records, which together comprise a CLDATA file. 1) O IS0 2000 -All rights reserv
