How to analyze the offset of the origin of the CNC machine program The professional CNC machining manufacturer teaches you how to analyze the offset of the origin of the CNC machine program. In the programming process, in order to avoid the size conversion, the workpiece coordinate system can be translated. The workpiece coordinate system (programming coordinate system) origin is translated to the workpiece reference, called the offset of the program origin. In general, CNC machine tools can set up six (C54 - C59) workpiece coordinate systems. The values ​​of the coordinate origin of these coordinate systems in the machine coordinate system can be input by manual data input, stored in the CNC machine memory, and still exist when the CNC machine is restarted.
Once one of C54~C59 is specified, the origin of the workpiece coordinate system is the current program origin. The absolute coordinates of the workpiece in the subsequent block are relative to the origin of the program. For example, the following program: Welcome to the company's official website http:/ /
N01 C54 COO C90 X30 Y40, N02 C59N03 COO X30 Y30, when executing N01 sentence, the system will select the G54 coordinate system as the current workpiece coordinate system, and then execute the coo to move to the ^ point in the coordinate. When executing the N02 sentence, the system will select the C59 coordinate system as the current workpiece coordinate system. When the N03 sentence is executed, the tool will move to point B in the C59 coordinate system just specified, as shown in Figure 2-18. The C92 command requires a coordinate value to specify the current workpiece coordinate value. Therefore, a separate block designation is required. Although there is a position command value in this block, it does not produce a cow movement. In addition, before using the G92 command, the CNC machine must be guaranteed to be at the machining start point, which is called the tool setting point.
When the workpiece coordinate system is established using G54~C59, the command can be specified separately or in the same segment as other programs. It should be noted that when the C54~G59 is used to create the coordinate system, if there is a position command in the program, motion will be generated. Before using this command, you should first input the coordinate origin of the coordinate system by MDI, and then use the corresponding C54~C59 in the program to establish the zero coordinate system, and use the CNC machine positioning command to move the white position to the T position. Start point.
Flexible rubber soft joint is also called Rubber Joint, rubber flexible joint, soft joint, shock absorber, pipeline shock absorber, shock absorber throat, etc. It is a kind of high elasticity, high air tightness, medium resistance and weather resistance. The pipe joint is a hollow rubber product that acts as a flexible connection between metal pipes
The rubber soft joint products take advantage of the advantages of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. High pressure, high temperature mold vulcanization. It has high internal density, can withstand high pressure, and has good elastic deformation effect. Shock absorption, noise reduction, lightweight, non-toxic.
According to the shape, it is divided into: concentric and same diameter, concentric reducer, eccentric reducer.
According to the structure, it is divided into: single sphere, double sphere, elbow sphere.
According to the connection form, it is divided into: flange connection, threaded connection, threaded pipe flange connection.
Flange for connecting rubber joint: DIN BS ANSI JIS standard
Working pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa
Working temperature: -40 degrees to 80 degrees (also can process high temperature resistant rubber soft joints)
Material of main parts
Ball body: natural rubber, neoprene, butyl rubber, nitrile rubber, fluorine rubber, EPDM
Inner and outer lining: natural rubber, neoprene, butyl rubber, nitrile rubber, fluororubber, EPDM, PTFE
Main Frame: Nylon Cord Flange: Cast, Forged Carbon Steel (Q235), Stainless Steel (201, 304, 316, 321), Plastic (PVC, PPC)
The flexible rubber soft joint solves the problem of different diameters when connecting metal pipes, and also has the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It is used in connection with pumps and Valves, pipelines with large vibration, and pipelines with frequent changes in cold and heat.
Rubber soft joint products have high pressure resistance, good elasticity (axial and lateral angular displacement), noise reduction, light weight, shock absorption, easy installation, flexible use, easy replacement and maintenance, and have acid resistance, alkali resistance, oil resistance, etc. Features.
Can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other pipeline systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -15℃~120℃. The special type is used to transport the above-mentioned medium or oil, concentrated acid and alkali, and solid materials above -30℃~250℃.
Applicable media: sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
When using or storing the flexible rubber joint, avoid high temperature, ozone, oil and acid-base environment. A sunshade frame should be built for pipes used outdoors or facing the sun and wind, and it is strictly forbidden to expose to the sun, rain, and wind erosion. The surface of the joint is strictly prohibited to be painted and wrapped with thermal insulation materials. Due to the aging problem of rubber products, it should be checked and replaced in time.
