Difficulties in 5-axis machining

The method and machine tool of five-axis machining, as early as the 60s of the 20th century, the foreign aviation industry has begun to adopt it in order to process some large pieces with continuous smooth and complex free-form surfaces, but it has not been widely used in more industries, and it has only developed rapidly in the past 10 years. The main reason is that there are many difficulties in five-axis machining, such as: 1. Programming is complex and difficult. Because five-axis machining is different from three-axis, in addition to three linear movements, there are two rotational movements involved, and the spatial trajectory of the resulting motion is very complex and abstract, which is generally difficult to imagine and understand. For example, in order to process the required spatial free-form surface, it is often necessary to go through multiple coordinate transformations and complex spatial geometric operations, and at the same time, it is necessary to consider the coordination of the movement of each axis, avoid interference, collision, and interpolation motion should be timely and appropriate, etc., so as to ensure the required machining accuracy and surface quality, and the programming difficulty is even greater. Second, the requirements for CNC

The development trend of five-axis machine tools

The first is the linear motor drive technology. After more than ten years of development, linear motor technology has been very mature. The problem of susceptibility to interference and large heat production has been solved, and the positioning technology of linear motor not only stops quickly in high-speed movement, but also some machine tool manufacturers use damping technology to solve it. The advantages of linear motors are linear drive, no transmission chain, no wear, and no backlash, so they can achieve the best positioning accuracy. Linear motors have high dynamics and can accelerate more than 2 g. The linear motor drive also has the characteristics of high reliability and maintenance-free. The second is the use of dual-drive technology. For the wider workbench or gantry type, if the intermediate drive is adopted, the driving force can not be guaranteed to be in the center, which is easy to cause tilting, so that the dynamic performance is poor. With dual drivers, dual encoders, and one driver module, the dynamic performance is perfect. One drive command, two drives work at the same time, the grating ruler to detect whether the two points are balanced, if not, through different commands to achieve balance. Of

The influence of temperature on the machining accuracy of the machine tool

Thermal deformation is one of the reasons that affect the machining accuracy, the machine tool is affected by the change of the ambient temperature of the workshop, the heating of the motor and the friction of mechanical movement, the heat of cutting and the cooling medium, resulting in the uneven temperature rise of each part of the machine tool, resulting in the change of the shape accuracy and machining accuracy of the machine tool. For example, if a 70mm×1650mm screw is machined on a CNC milling machine with ordinary precision, the cumulative error of the milled workpiece from 7:30 a.m. to 9:00 a.m. can vary by up to 85m compared with the workpiece processed from 2:00 p.m. to 3:30 p.m. At constant temperature, the error can be reduced to 40m. For another example, a precision double-end grinding machine for double-end grinding of 0.6~3.5mm thick thin steel sheet workpieces, processing 200mm×25mm×1.08mm steel sheet workpieces can achieve mm dimensional accuracy, and the bending degree is less than 5m in the full length. However, after continuous automatic grinding for 1 hour, the size change range increased to 12m, and the coolant temperature increased from 17°C at start-up to 45°C. Due to the influence

Advantages of 5-axis linkage machines

The so-called five-axis machining here refers to the fact that there are at least five coordinate axes (three linear coordinates and two rotary coordinates) on a machine tool, and the simultaneous coordinated movement can be processed under the control of the computer numerical control (CNC) system. Compared with the general three-axis linkage CNC machining, such five-axis linkage CNC machining has the following advantages: 1. It can process continuous and smooth free-form surfaces that cannot be processed by general three-axis CNC machine tools or are difficult to be processed in one clamping. For example, the blades of aero engines and steam turbines, the screw thrusters used in ships, and many shells and molds with special curved surfaces and complex cavities and hole positions, such as ordinary three-axis CNC machine tools, because the attitude angle of the tool relative to the workpiece cannot be changed in the processing process, when machining some complex freeform surfaces, there may be interference or underprocessing (that is, it cannot be processed). When processing with a five-axis linkage machine tool, the attitude angle of the tool/workpiece can be adjusted at any time during the machining process, the interference of the tool workpiece can be avoided and all

Rationalization of milling cutter selection

1. Reasonable choice of milling tool applications with different tooth counts Sparse-tooth milling cutters are unequal-pitch milling cutters. Because of the wide chip-bearing groove, they are suitable for milling long-chip metals such as stainless steel and aluminum alloy; and because the milling cutter has a small number of teeth milling metal at the same time, the cutting force generated is small, which is suitable for low-power spindle machine tools or workpieces with weak workpiece clamping. Dense-tooth milling cutters are milling cutters with moderate number of teeth and have a wide range of versatility. They are usually recommended as the first choice.When the milling cutting force is required to be small, the method of reducing the number of blades is usually adopted, but the adjacent positions must be removed evenly. Special dense tooth milling cutters are used in machine tools with sufficient spindle power. When the workpiece is clamped enough, the high-efficiency metal removal rate of large cutting depth and large tool walking can be obtained.It is also suitable for milling metals such as gray cast iron that require low chip capacity. 2. Reasonable choice of tool diameter The choice of milling cutter diameter is usually based on the width of
