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.

In the design of machining process regulations, the development of process routes is the core skeleton of the entire process design, which directly determines whether the parts processing accuracy can meet the standards, high and low production efficiency, manufacturing costs are controllable. Many new craftsmen often make mistakes

The main reason why novice welders can't match the current and voltage is that they don't know the relationship between the two, and they don't know what role they play. Current is to control the weld depth (current can also be understood as the wire feed speed, the greater the current, under the condition of constant voltage).

FANUC system CNC milling machine / machining centre programming and operation 1.1.1 Classification of CNC machine tools 1.1 Overview of CNC milling machine / machining centre 1.1.1 Classification of CNC machine tools CNC machine tools are machine tools that are controlled using CNC technology. Classified according to their processing purposes

G76 instruction and G92 are the same as turning threads, the difference is that G92 is a simple cycle, G76 is a composite cycle, G76 only need to specify the cycle of thread processing location and the last cut thread end coordinates can be. This instruction can be used to turn isometric straight threads and taper threads.

First of all, to just come in the friend to introduce the introduction of argon arc welding, two bonded welding, plasma welding, laser welding, the working principle of each and its advantages. Convenient to learn or to enter the processing industry bosses to choose. Argon arc welding argon arc welding arc using high-pressure breakdown of the arc starting method

2026 Huizhou high-precision aluminium alloy shell CNC machining manufacturers Top3 recommended with drones, optical equipment, medical equipment and other industries to high-precision, lightweight upgrade, aluminium alloy shell CNC machining demand continues to rise

01 Overview of assembled steel structure nodes China has promoted the development of assembled buildings in recent years, and the assembled connection nodes of square steel tube columns and beams have gradually become a research hotspot because of their high efficiency and environmental advantages. Assembled steel structure is different from traditional building structure, it is prefabricated in the factory.

Mechanical engineers are the core force driving the development of modern industry, but if you want to go from entry to mastery in this field, practical experience alone is far from enough. Today, I have selected for you 10 mechanical engineers must read the classic books

This book focuses on how to control welding deformation. The contents include the law of welding deformation and the calculation of welding bending deformation of beams and columns, the calculation of pre-arching of the web plate of box girders of welded plate structures, the method of reducing welding deformation
