The present invention relates to ships, and in particular relates to a method of modifying the structure of a ship. BACKGROUND TECHNOLOGY: 1. The hull structure needs to be modified during the construction of a ship, and it is common to divide a modification area in the hull and remove the original structure in the modification area

The application of CNC technology has made a qualitative change in the traditional manufacturing industry, especially in recent years. The development of microelectronics technology and computer technology has brought new vigour to CNC technology. CNC technology and CNC equipment is an important foundation for the industrial modernisation of each country.

First, in order to ensure that the thread of the guide, processing spindle rotation week, the feed of the tool must be equal to the thread of the guide, the feed is larger; in addition, the strength of the threaded tool is generally poor, so the threaded tooth type is often not once processed, the need for many times for cutting.

Steel structure welding deformation and control correction method, a good collection.

X, Z for the thread end point (point C) coordinates; U, W starting point coordinates to the end point coordinates of the incremental value; R for the cone thread end point radius and the starting point radius of the difference between the R value of positive and negative judgement and G90 the same way, cylindrical threads R = 0, can be omitted; F for the pitch value.

Industrial photogrammetry is one of the more popular non-contact, wide-area scene measurement techniques today, with relatively mature technology development and a wide range of applications.

Versatility: Turning and milling compound lathe can carry out turning, milling, drilling, tapping and other machining operations, which reduces the number of workpiece clamping and machining time. As an advanced processing equipment, mill-turning lathe is characterised by its versatility, high precision and high efficiency.

High carbon steel is often used in high end kitchen knives as it is hard wearing, meaning it stays sharper for longer. Steel is found in everything from aerospace to kitchenware. Such diverse applications require a versatile material - and steel fits the bill.
