How to make five-axis CNC machining simple and convenient

Four simplified steps

The new concept of advanced machining functions is based on the view that any five-axis machining function (no matter how complicated) can be defined in a few simple steps. The mold manufacturer has adopted a tried and tested method to set up the mold production program:

(1) The area to be processed and the processing sequence. This step is based on the complexity of the shape of the part, and is often the easiest to inspire the inspiration of a skilled mechanic.

(2) What shape should the tool trajectory in the machining area have? Should the tool cut in the order of front and back or up and down according to the parametric lines of the surface, and use the surface boundary as a guide?

(3) How to guide the tool axis to match the tool path? This is very important for the quality of the surface finish and whether to use a short hard tool in a small space. The mold maker needs to fully control the tool, including the fore and aft inclination when the tool is tilted. In addition, it is necessary to consider the angular limit caused by the rotation of the worktable or tool post of many machine tools. For example, there are limits to the degree of rotation of milling/turning machine tools.

(4) How to convert the cutting path of the tool? How to control the displacement of the tool due to reset or displacement and the displacement that the tool must produce between the machining areas at the starting point of the tool path? The displacement produced by the conversion process is very critical in mold production. It can eliminate the traces of the witness line and the tool (which can be removed by manual polishing afterwards).

New ideas

Following the idea of ​​a machinist when deciding to perform five-axis machining on complex parts is a better way to develop CAM software. Why decompose five-axis machining functions instead of developing a familiar and easy-to-understand single programming process for programmers?

This advanced technology will eliminate the contradiction between powerful functions and ease of use. By simplifying the multi-axis machining method into a unique function, users can quickly make full use of all the functions of the product. With this new function of CAM, five-axis machining can be maximized flexibility and compactness.
