操作人员开始 cnc零件加工 时要把进给速度调到很小，单节执行，快速定位、落刀、进刀时须集中精神，手应放在停止键上有问题立即停止，注意观察刀具运动方向以确保安全进刀，然

Technical Brief: This patent proposes an automatic loading and unloading mechanism for the problems of low efficiency and big safety risks of manual loading and unloading in traditional bar processing. Through the hydraulic drive lifting body with pneumatic horizontal moving device, to achieve synchronous lifting and transverse displacement of the block

钢结构在我国的制造和建筑的行业当中已经普遍施行，它的工程质量直接影响了我国经济的发展，而钢结构在加工的过程当中焊接过渡、结构变形、焊接点不稳定等等各类的问题都是存在的

CNC turning and milling is an advanced machining technology and is currently one of the most widely used processes in the field of mechanical engineering. In our traditional machining methods, each step and process is carried out using a specific machine tool.

In the field of machining, shaft parts are the core basic parts of all kinds of machinery and equipment, mainly bear the role of supporting transmission parts, transferring motion and torque, and its processing quality directly determines the operating accuracy and service life of the equipment. From smooth shafts to shaped shafts, from rough turning to fine grinding.

Machining parts surface texture defects detection of the method of research.doc, machining parts surface texture defects detection of the method of research Abstract: With the improvement of China's industrial development level, the degree of modernisation of industrial production is increasingly high.

Technical Brief: This patent proposes an automatic turning device for the problem of low efficiency and high safety risk caused by traditional plate turning relying on manual or travelling vehicle operation. The 180°turning of the workpiece is realised by the rotating structure of the clamping part and the longitudinal beam, together with the design of the limit device and concave table.

Case study: A shipyard discovered linear defects during ultrasonic testing (UT) of a test piece following welding. Analysis revealed that the defects were caused by excessive welding speed, resulting in lack of fusion. After adjusting the speed, the weld was re-performed and passed the assessment. Scope: A single WPS may be supported by multiple PQRs.
