Full title and description

St ISO 6582-1983 — Shipbuilding — Numerical control of machines — ESSI format. This International Standard defines the ESSI block and data-word format used to exchange numerical-control (NC) programs and geometric data between NC drawing machines and flame-cutting/NC machines in the shipbuilding industry, promoting uniform programming techniques and interchangeability of programs.

Abstract

Serves as a guide for the coordination of system design to minimize program variety, promote uniformity of programming techniques and foster interchangeability of programs between NC drawing machines and flame-cutting machines used in shipbuilding. The ESSI format may be used with punched cards, punched tapes, magnetic tapes or other data media; use of standardized data codes is recommended.

General information

• Status: Withdrawn (International Standard withdrawn from ISO catalogue).
• Publication date: April 1983 (ISO edition 1, 1983-04).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 35.240.60 (IT applications in transport); 47.020.70 (Navigation and control equipment / shipbuilding control).
• Edition / version: Edition 1 (1983).
• Number of pages: 9 (ISO catalogue listing).

Scope

The standard specifies the ESSI block and word formats used to represent geometric primitives (lines, circular arcs, parabolic arcs) and machine auxiliary functions for NC applications in shipbuilding. It is intended as a coordination guide to reduce incompatible program formats and to facilitate data interchange between different manufacturers’ NC drawing and flame-cutting machines. The format covers block delimiters, end-of-block characters, axis and dimension word formats, initialization blocks and conventions for machine-function words.

Key topics and requirements

• Definition of ESSI block structure and maximum characters per block (variable block formats and fixed rules for initialization blocks).
• Specification of dimension words and their meaning: two words for straight lines; five words for circular arcs (DX, DY, XC, YC, TC); six words for parabolic arcs, etc.
• Addressing rules for axes and non-dimension words (machine functions / auxiliary functions), including digit limits and signed/unsigned conventions.
• End-of-block and record-delimiter conventions (LF, CR or both) and recommendations for initialization characters to support automatic code detection.
• Recommendations for use with various physical media (punched cards, tapes, magnetic media) and encouragement to adopt standardized data codes for interchange.

Typical use and users

Primary users were shipyards, naval architects, NC/CAD-CAM programmers, machine-tool manufacturers (NC drawing and flame-cutting machines), and systems integrators working on data interchange for plate cutting and hull-form generation. The format was used where consistent, portable NC program exchange was required across different equipment and suppliers; some national bodies adopted or referenced ISO 6582 when implementing their own NC data interchange rules.

Related standards

Related and complementary standards include ISO 6983 (Numerical control of machines — program format and remarks for tape format / CNC program standards), various shipbuilding shiplines and data-organization standards (e.g., ISO 7461, ISO 7838) and national adoptions/adaptations such as GB/T 22217 (China) which has adopted ISO 6582:1983 text as an identical national standard. These documents address broader CNC program formats, shiplines data and other data-exchange conventions.

FAQ

Q: What is this standard?

A: ISO 6582:1983 is an International Standard titled "Shipbuilding — Numerical control of machines — ESSI format" that defines a block and data-word format (ESSI) for exchanging NC program data used in shipbuilding.

Q: What does it cover?

A: It covers the ESSI block structure, dimension-word conventions for geometric elements (lines, circular and parabolic arcs), addressing and machine-function words, end-of-block delimiters and guidance for using the format with punched cards, tapes or magnetic media to promote interchangeability between NC drawing and flame-cutting machines.

Q: Who typically uses it?

A: Historically, shipyards, NC/CAD-CAM programmers, machine-tool and controller manufacturers, and systems integrators concerned with program portability and data exchange in shipbuilding and plate-cutting operations. National standards bodies and some industry suppliers referenced or adopted the format for local use.

Q: Is it current or superseded?

A: ISO 6582:1983 is listed as Withdrawn in the ISO catalogue (withdrawal confirmed in ISO lifecycle records). It does not appear to have an active ISO replacement under the same number; other CNC/program-format standards (for example ISO 6983 and various national adoptions) cover related needs and have been used in parallel or instead. Catalogues and national bodies show the standard withdrawn from sale.

Q: Is it part of a series?

A: It sits in the family of ISO documents addressing numerical control, shipbuilding data formats and shiplines conventions; related ISO items include ISO 6983 (general NC program format) and other shipbuilding information-processing standards (e.g., ISO 7461, ISO 7838). Some national standards bodies issued identical/adopted versions under their national catalogues.

Q: What are the key keywords?

A: ESSI format, NC, numerical control, shipbuilding, data interchange, tape/punched-code formats, block format, dimension words, flame-cutting, NC drawing machines.
