CNC five axis computer gong processing technology

It is a difficult point for five axis parts to process multi-dimensional surface parts. In addition to the application of multi axis machine tool, multi axis programming technology is the key. Reasonable setting of machining tool path is an important guarantee for the surface accuracy and dimensional accuracy of parts. Five axis parts processing taking human head image processing as an example, this paper discusses and analyzes the practical application of five axis cutting to multi-dimensional surface parts processing.

Five axis parts processing has the characteristics of high efficiency and high precision, the workpiece can complete complex processing with one clamping. It can adapt to the processing of modern molds such as auto parts and aircraft structural parts. There is a big difference between five axis machining center and pentahedron machining center. Many people don’t know the five axis machining, and mistakenly regard the pentahedron machining center as the five axis machining center. Five axis machining center has x, y, Z, a, C five axis, XYZ and AC axis form five axis linkage processing, good at space surface processing, special processing, hollow processing, drilling, oblique hole, oblique cutting and so on. Five axis parts processing and “pentahedron machining center” is similar to the three-axis machining center, but it can do five faces at the same time, but it can’t do special-shaped processing, oblique hole, cutting slope, etc.

A five axis machining type for mechanical parts relates to a five axis manipulator. Its main features are that the shoulder mechanism and the reducer shaft of the waist mechanism fixed on the fixed seat are fixedly installed to realize the radial swing of the shoulder mechanism and the reducer shaft of the fixed seat, the elbow mechanism and wrist mechanism for five axis mechanical parts processing realize the relative swing between the shoulder mechanism and the elbow mechanism, and the elbow mechanism and wrist mechanism respectively, and the five axis mechanical parts processing claw mechanism is installed on the bevel gear shaft of the wrist mechanism and passes through A pair of gears installed on the wrist mechanism reducer are meshed with the bevel gears of the claw mechanism.

Five axis machine parts processing type has simple structure, comprehensive functions, good reliability, stability and accuracy of the whole machine. It can perfectly replace the existing manipulator, and is suitable for welding, assembly, processing and other industrial systems. Five axis mechanical parts processing CS Series manipulator is suitable for 500 ~ 3000 tons of various types of horizontal injection molding machine products and nozzle extraction. The upper and lower arm type is variable section type; the up and down stroke is 800 ~ 3000mm, and the X, y, Z three axes are driven by AC servo motor. The installation can increase the production capacity (20 ~ 30%), reduce the defective rate of products, ensure the safety of operators, reduce labor, accurately control the production volume, and reduce waste.

The five axis mechanical parts processing is driven by drive components such as motor, reducer, pulley mechanism, sprocket mechanism, etc. it is characterized in that: the manipulator includes waist mechanism, shoulder mechanism, elbow mechanism, wrist mechanism and claw mechanism. The five axis mechanical parts processing shoulder mechanism and the reducer shaft of waist mechanism fixed on the fixed seat are fixed together The elbow mechanism and wrist mechanism are respectively installed in the shoulder mechanism and the reducer in the elbow mechanism to realize the relative swing between the shoulder mechanism and the elbow mechanism, and between the elbow mechanism and the wrist mechanism. The five axis mechanical parts processing claw mechanism is installed on the bevel gear shaft of the wrist mechanism, and is installed on the reducer of the wrist mechanism The engagement of a pair of bevel gears with the claw mechanism realizes the swing or rotation of the claw mechanism.

Five axis impeller machining supports four axis roughening, and some manual settings can be made in the control of the axis. Of course, in the process of generating the program, automatic avoidance can adjust these parameters. Channel finishing method is mainly used to finish the channel surface of five axis impeller. Various finishing strategies provide different optimization path distribution and tool inclination calculation methods for tasks. Similarly, the five axis impeller machining also supports the four axis mentioned above and the manual setting of tool tilting and other functions.

Five axis impeller machining point is to use the tool point contact method to process the blade surface with continuous and spiral circular action. In this method, a variety of machining modes and feeding strategies are provided to adapt to different tasks, such as the cavity mode of five axis impeller machining to reduce the vibration of adjacent blades. The strategy also supports the four axis and manual tool tilting functions mentioned above.

Five axis impeller machining is a kind of typical free-form surface parts. If the traditional cam machining strategy is adopted, different machining directions need to be tested repeatedly, and the paths of different directions need to be connected through human intervention, which will take a lot of time to adjust. Traditional machining methods are time-consuming and difficult to ensure accuracy. HyperMILL? Provides professional machining modules for both open and closed five axis impeller machining, so that even users with less experience in machining can program NC programs of this kind of parts which are difficult to complete by using conventional programming strategy in a short time through simple settings. This specialized module is commonly used in various fields of five axis impeller processing.
