Then, a composition detecting step is performed to detect the composition ratio of the deposit layer, wherein the deposit layer is on the surface of the workpiece. Next, a wear particle diameter detecting step is performed to detect at least one wear particle diameter of at least one of the abrasive chips generated during processing of the workpiece. Then, it is judged whether the at least one wear particle diameter wear particle diameter is within a preset wear particle size range to provide a first judgment result. Next, it is judged whether the composition ratio is within the preset composition ratio range to provide a second judgment result. Then, the surface quality of the workpiece is determined based on the first determination result and the second determination result.

According to another embodiment of the present invention, in this processing method, a processing machine and a workpiece are first provided. Then, a preset wear particle size range and a preset composition ratio range are provided. Then, a machining process is performed to machine the workpiece using the processing machine. In this processing, a composition detecting step is first performed to detect the composition ratio of the deposit layer, wherein the deposit layer is on the surface of the workpiece. Then, an abrasion particle diameter detecting step is performed to detect at least one abrasion particle diameter of at least one of the abrasive chips generated during processing of the workpiece. Next, it is determined whether the at least one wear particle diameter is within a preset wear particle size range to provide a first determination result. Next, it is judged whether the composition ratio is within the preset composition ratio range to provide a second judgment result.

Referring to FIG. 1 and FIG. 2 together, FIG. 1 is a schematic flow chart showing a method 100 for detecting a surface quality of a workpiece according to an embodiment of the present invention, and FIG. 2 is a view showing a processing machine 200 according to an embodiment of the present invention. Schematic diagram of the structure. In the present embodiment, the processing machine table 200 is a rolling mill for rolling the workpiece W, and the workpiece W may be an aluminum plate. However, embodiments of the invention are not limited thereto. In other embodiments of the present invention, the processing machine 200 may be a press, and the workpiece W may be made of other metals such as steel or copper.

In the workpiece surface quality detecting method 100, a preset condition providing step 110 is first performed to provide a preset wear particle size range and a preset composition ratio range. In the present embodiment, when the processing machine 200 rolls the workpiece W, a deposit layer (also referred to as a film) is formed on the surface of the workpiece 210 (ie, the roll) of the processing machine 200, and the preset is formed. The composition ratio range is used to define a combination of qualified deposit layer components. In addition, when the processing machine 200 rolls the workpiece W, the contact surface of the workpiece W and the workpiece 210 generates wear debris, and the predetermined wear particle size range and the defined abrasive particle size are defined.

For example, in the laboratory, a Bowden test is performed on the aluminum plate samples to obtain a working fluid friction coefficient (RT) under various rolling conditions, as shown in FIG. Then, according to the results of the package test, the preset wear particle size range and the preset composition ratio range are defined. Taking the third figure as an example, the test result of the code SC is optimal, so the wear particle size range and the sediment layer composition group in this rolling condition can be used as the preset wear particle size range and the preset composition. The scale range is shown in Figure 4. Since the test result of the code is SC is optimal, the composition ratio is set to 1 to facilitate comparison with other test results.

In the present embodiment, the preset composition ratio range is defined by plus or minus 15% of the composition ratio of the code SC, but the embodiment of the present invention is not limited thereto.

After the preset condition providing step 110, the composition detecting step 120 and the abrasion particle size detecting step 130 are next performed to monitor the surface quality of the workpiece for the in-line processing.

The composition detecting step 120 detects the composition ratio of the deposit layer. In the present embodiment, the composition detecting step 120 detects the ratio of the working element to oxygen. For example, when the material of the workpiece is aluminum, the composition detecting step 120 detects the aluminum/oxygen ratio of the deposit layer. When the material of the workpiece is iron, the composition detecting step 120 detects the iron/oxygen ratio of the deposit layer. Additionally, the composition detection step 120 can be performed using filter paper to provide immediate analysis results.

The wear particle diameter detecting step 130 detects the size (also referred to as particle diameter) of the wear debris generated when the workpiece 210 is processed. During the processing, the friction between the workpiece 210 and the workpiece w generates wear debris, and the present invention The embodiment utilizes this wear debris as an assessment of the surface quality of the workpiece 210. In a general processing process, the showerhead 220 sprays machining fluid onto the workpiece 210 and the workpiece W to lubricate and cool the surfaces of the workpiece 210 and the workpiece W. A part of the machining liquid carries away the abrasive chips and flows into the container 230 below the processing member 210, and the abrasion particle diameter detecting step 130 of the present embodiment analyzes the abrasion debris contained in the machining liquid in the container 230 to obtain these.

In the determining step 140, it is determined whether the abrasion particle diameter detected by the abrasion particle diameter detecting step 130 is within a preset abrasion particle size range to provide a first determination result, and in the determining step 150, determining the composition The aluminum/oxygen ratio detected by the detecting step 120 is within a preset composition ratio range to provide a second determination result.

Next, a quality determining step 160 is performed to determine the surface quality of the workpiece 210 based on the first determination result and the second determination result. For example, when both the first determination result and the second determination result are YES, it means that the surface quality of the workpiece 210 is excellent. For another example, when one of the first judgment result and the second judgment result is NO, it indicates that the surface quality of the workpiece 210 is not good.

It can be seen from the above description that the surface quality detecting method 100 of the workpiece according to the embodiment of the present invention uses the particle size of the wear debris and the composition of the surface deposit of the workpiece to judge the surface quality of the workpiece, so that the surface quality is judged. Knowing the technology is more accurate.

Then, a processing machine control step 570 is performed to control the processing machine 100 in accordance with the surface quality of the workpiece 210. For example, when the first determination result is NO, it means that the wear particle diameter is too large, and the surface quality of the workpiece 210 is not good. At this time, the processing machine control step 570 controls the processing machine 100 to change the proportion of the lubricating fluid to control the wear particle size within a predetermined particle size range. For another example, when the second determination result is negative, it indicates that the oxide is excessive, and the surface quality of the workpiece 210 is not good. At this time, the processing machine control step 570 controls the processing machine 100 to change the proportion of the cooling liquid to control the ratio of the working element/oxygen to be within the preset composition ratio range.

As can be seen from the above description, the processing method 500 of the embodiment of the present invention controls the processing machine 100 by the workpiece surface quality detecting method 100 to avoid affecting the quality of the finished product due to insufficient lubrication or insufficient cooling.
