Description

Method for Producing Cutting Drawing of Stainless Steel Section Type and for Abstracting BOM at the Time of Designing Vessels}

The present invention relates to the automatic generation of manual section cutting drawings and automatic material bill of material (BOM) extraction in the design of ships during ship manufacturing. In particular, the information to be shown in the drawings is automatically generated using ship modeling data and data. The present invention relates to the automatic generation of section steel cut drawings and the automatic material BOM extraction during ship design, which automatically extracts the material BOM with the nested results and drawings.

The manufacturing process of a ship goes through a number of different processes, depending on the field of work and the content. One of them is design cut drawing for members such as round bar, half round bar, beam member with flat, curved or knuckle shape. The worker decides the shape, length, material, etc. of the member by hand and draws the necessary information by hand through the key in and drawing work in the specific drawing form. The method was drawn manually and the shapes were drawn and displayed. That is, in the prior art, drawings were made using a manual work method.

The design of ship is divided into many fields from basic design to production design drawing. In general, when the production design drawing stage required for the production stage is completed, modeling is completed and various drawings are created using modeling information and parts information is created. . During this design process, the design parts that are not yet supported by IT-based technology or CAD system technology are designed using manual design methods. Each member of the structure of the ship is made through the assembly process after the cutting operation, the type and shape of the members constituting the structure of the ship is divided into a number of types, and the drawing method and the cutting, processing methods are different.

In addition, various kinds of raw materials including steel sheets are used for various raw materials used to make ship structures. Shape steel materials such as round bar (HRB), round bar (HRB), beam, etc., which are covered in the present invention, are processed according to use and shape. Create and construct the member. In general, R.B, H.R.B, Beam and the like may be accompanied by a bending work depending on the use, at this time, the drawing process for cutting and part information steel ordering information creation step of the work process. The designer prepares drawings of the RB, HRB, Beam, etc., and designs, draws a specific drawing form, and uses the computer to designate the information to be shown in the drawings such as the shape, length, and dimensions of various members. It is shown in the form and it is currently being written by hand.

In addition, although the bill of materials (BOM) and steel ordered bill of materials (BOM) information are used by computer hardware and software systems, the text table is used to create a list table. As a result, the cause of increased ship design M / H (Man / Hour) input and quality deterioration due to designer error is always included, and there is a problem such as occurrence of raw material loss caused by design error.

That is, in the related art, the designer manually calculates and draws the drawing using only a computer design drawing program, and then goes through a design process such as selecting a drawing form → drawing a member shape → designing various types of information for drawing city → creating steel ordering information.

Therefore, as the design process depends on manual work, design M / H increases, and depending on the designer's judgment and manual ability, many errors occur unlike the initial modeled design contents, causing design quality deterioration. As a result of the rework caused by the occurrence of additional raw materials, there was a problem that the loss caused by the rework.

No prior art document
