The operation and programming skills of 5-axis CNC machining are closely related, and if the user adds special functions to the machine, the programming and operation will be more complex. Only repeated practice, programming and operation personnel can master the necessary knowledge and skills. Experienced programming, the lack of operators, is a major resistance to the popularity of five-axis CNC technology.
Many domestic manufacturers from abroad to buy five-axis CNC machine tools, due to technical training and services are not in place, five-axis CNC machine tools inherent functions are difficult to achieve, the machine utilization rate is very low, many occasions is not as good as the use of three-axis machine tools.
Five-axis machine tool motion is the synthesis of five coordinate axis motion. The addition of rotary coordinates, not only increased the burden of interpolation, and the small error in the rotary coordinates will significantly reduce the machining accuracy. Therefore, the controller is required to have a higher accuracy of operation.
Five-axis machine tool motion characteristics require servo drive system has very good dynamic characteristics and a large range of speed regulation.
Five-axis NC NC program verification is particularly important
To improve the efficiency of machining, the urgent need to eliminate the traditional “trial cut method” verification method . In the five-axis CNC machining, NC program verification work has also become very important.
Because of the high cost of workpieces usually machined with 5-axis CNC machines, collisions are a common problem in 5-axis CNC machining: tools cutting into the workpiece; tools hitting the workpiece at very high speeds.
The tool collides with machine tools, fixtures and other equipment within the machining range; moving parts on the machine collide with fixed parts or workpieces. In 5-axis CNC, collisions are difficult to predict, and the calibration procedure must be a comprehensive analysis of the machine tool kinematics and control system.
