Problems solved by technology

[0004] ① In order to achieve better cutting performance of different tools, programmers need to modify the processing program repeatedly according to the cutting parameters provided by different tool manufacturers, which increases the workload of programmers, and the tool trial cutting cycle is long;
[0005] ②Using the final product delivered to the customer for tool trial cutting, for the factory, there is a great product quality risk;
[0006] ③In the production site of the factory, there is generally no force measuring equipment and tool wear testing equipment required for professional tool test cutting, and it is impossible to use the laboratory's "cutting force and tool flank wear" and other indicators to perform cutting of the tested cutting tool performance evaluation

Embodiment 1

[0045] This embodiment provides a method for rapid trial cutting and cutting parameters optimization of CNC milling tools, which is suitable for production sites, and includes the following steps:

[0046] Step 1. Design as figure 2 The shown inclined block is used as the processed standard trial cutting piece 2 of the cutting tool 1 to be tested, and the angle of the inclined plane is 10-15 degrees.

[0047] Step 2: Install the general-purpose vise on the machine table 3 and align it, and use the vise 4 to clamp the standard trial-cut piece to establish a processing coordinate system.

[0048] Step 3: call the standard trial cutting processing program, and modify the cutting parameter variables of the standard trial cutting processing program as required. The standard trial cutting process is shown in Table 1.

[0049] Among them, the standard trial cutting processing program is designed with a macro program, and the main axis speed Vc, tool diameter D, tool feed per tooth...

Embodiment 2

[0077] On the basis of embodiment 1, more specifically, according to the reference cutting parameters provided by the tool supplier and the processing experience of the enterprise, such as, the cutting line speed Vc of a certain tool (diameter d=10mm, number of teeth Z=5) processing superalloy material =60~80m / min, feed per tooth Fz=0.05~0.12mm / tooth, then the calculation method of the optimal feed per tooth Fz and cutting linear speed Vc of the tool is as follows:

[0078] Parameter selection for the first experiment: According to the principle of the golden section method "(big-small)*0.618+small", that is

[0079] Fz1=((0.12-0.05)*0.618)+0.05≈0.093;

[0080] Vc1=((80-60)*0.618)+60≈72.36

[0081] Parameter selection for the second experiment: According to the principle of the golden section method, "the next point is selected as: (big + small - previous point)", that is:

[0082] Fz2=0.12+0.05-0.093=0.077

[0083] Vc2=80+60-72.36=67.64

[0084] Parameter selection for th...

Abstract

The invention discloses a method for rapid trial cutting and cutting parameter optimization of a numerically controlled milling tool, which belongs to the technical field of mechanical processing. In this method, at the production site, a standard trial cutting piece is used for trial cutting for different brands of cutting tools to be tested. The processing performance under the condition; and the optimal experimental method of the golden section is adopted to quickly obtain the optimal cutting parameters of the cutting tool, thereby improving the efficiency of the tool trial cutting, shortening the tool trial cutting cycle, and eliminating the quality risk of the product trial cutting.

Description

technical field [0001] The invention relates to the field of metal cutting, in particular to a method for rapid trial cutting and cutting parameter optimization of a numerically controlled milling tool. Background technique [0002] In the metal cutting process, the tool completes the cutting work, and its cutting performance directly affects the processing cost, processing quality and efficiency. In order to meet the rapid development of CNC technology, the update of CNC tool technology is changing with each passing day. Each tool manufacturer has developed different tool materials, coatings and tool geometric parameters for different workpiece materials, and each has its own characteristics. However, the application of CNC tools is uneven. In enterprises with good application of CNC machining technology, certain CNC tool selection specifications and tool cutting parameter libraries have been formed for use by CNC programmers in the workshop; In enterprises with poor appli...
