Problems solved by technology

[0002] CNC system machining centers generally run traditional G codes. Most systems only provide interfaces written online, and manual input of running instruction codes is based on artificial calculations. The processing code generated by the third-party CAM needs to be post-processed. At that time, an engineer who is specialized in the third-party CAM is required to process it, and the cost is relatively high; a few systems will also provide fixed programming modules with a few shapes, but the processing needs Ever-changing, simply can not meet the market demand
In response to the needs of the market, a few systems provide several packaged common graphics, such as chamfer, trapezoid, isosceles triangle, waist round groove, round hole groove, square groove, etc. ...

Abstract

The invention discloses a G68.2-based CAM processing method for plane machining in a numerical control system. According to the method, a machining figure is input into the numerical control system inthe form of point data of line segments and arcs forming the machining figure; plane machining is carried out after G68.2-based CAM processing in the numerical control system. The method is high in flexibility and just has low requirements for an operator, and the operator just needs to have plane geometry knowledge. The method can be compatible with a 3+N multi-axis system, such as double-swing-head equipment, swing-head rotary table equipment, single-swing-head equipment and single-rotary-table equipment; rich selectivity is provided, and groove milling and edge milling can be switched andselected; and the figure of a plane can be adapted to plane machining of different angles according to the plane rotation of the G68.2.

Example Embodiment

[0059] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Reference Figure 1-11 , The embodiment provided by the present invention: now an actual processed part is used for illustration:
[0060] Step Sa1: Determine the initial parameters, the angle of the processing knife (determine the G68.2 plane), the processing depth, whether the processing method is offset, the cutting and milling method, etc., such as Figure 4;
[0061] Step Sa2, add points (data blocks), first determine a straight line consisting of two points, such as Figure 5;
[0062] Step Sa3, add a clockwise half-circle arc, such as Image 6;
[0063] Step Sa4. After adding the points, select the G type (G02 clockwise arc), a dialog box for setting the arc will pop up, providing two ways of three points and two points, we check the two point method, and then enter the value, enter After clicking Calculate, click OK again, such as Figure 7;
[0064] Step Sa5. Whenever a bit (data block) is updated, the real-time path feedback graph will be updated, and the corresponding graph will be drawn. According to the data, compare whether the graph is the graph you want to set. If not, modify the data, and continue to the next step if you are sure ,Such as Figure 8;
[0065] Step Sa6. Add two straight lines to form a closed figure, such as Picture 9;
[0066] Step Sa7. Then save and generate G code. The G code path of contour milling is as follows: Picture 10;
[0067] Step Sa8, change the cutting and milling mode to area milling and save again, the G code path of area milling, such as Picture 11.
[0068] Finally, it should be noted that the above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, it is still for those skilled in the art. The technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be equivalently replaced. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention shall be included in Within the protection scope of the present invention.
