Problems solved by technology

[0004] The five-axis machining center can complete multi-angle machining, and can process any point that needs to be processed. However, the rotation methods of the five-axis axes on the market are different, such as rotation around the X and Y axes, rotation around the X and Z axes, or Y, Z axis rotation, using different rotating axis equipment to determine the spatial point must have different calculation methods
[0005] At this stage, the calculation of space points is mostly constructed in the brain first, and then assists the relevant software to calculate the space points. Because the rotation axes of 5-axis machine tools are different, the methods of determining the processing points are different, and there is no systematic calculation method. , resulting in a long time-consuming point determination and a high error rate in point calculation

Embodiment Construction

[0020] The following examples illustrate the point calculation method of complex spatial hole system programming in further detail. The specific steps are as follows:

[0021] Step 1. Use software and right-hand rule to establish a simplified three-dimensional model, the software has the function of coordinate system translation and rotation;

[0022] Step 2: According to the type of machine tool, including single disc and double disc, analyze and determine the 4th and 5th axis;

[0023] Step 3: Project the space axis to the 5th plane, analyze the angle between the projection line and the common axis; the plane parallel to the 5th axis is the 5th axis projection plane, referred to as the 5th plane; the plane parallel to the 4th axis is the first 4-axis projection plane, referred to as plane 4; the intersection line of plane 4 and plane 5 is the common axis;

[0024] Step 4. Determine whether the angle is positive or negative according to the right-hand screw rule to obtain the 5th axi...

Description

Technical field [0001] The invention belongs to the field of numerical control programming, and is a systematic calculation method for processing various five-axis equipment to spatial point positions. Specifically, it is a point calculation method for complex spatial hole programming. Background technique [0002] There are multi-angle oil passage holes, bushing holes, and pin holes for casing parts. Some of the holes require high position. In addition to custom-made special tooling for processing, it is necessary to use five-axis equipment for multiple rotation angles for processing. [0003] Part design drawings mostly come with three-dimensional digital models, which can be directly determined. However, some parts only include design drawings without three-dimensional digital models. The design drawing only gives the dimensions of the section position, section angle, height distance and other dimensions for the processed hole position. The need for processing is to find the po...
