Thus, the fixing of the cutting medium 4 is completed;

[0053] Place the cutting medium tooling 3 on the test bench 11, press the power-on key, and the unit value is defaulted to N. After the control panel 2 is powered on, press the zero-clearing key to clear the value on the display screen 21;

[0054] Next, move the tool support base 5 to a suitable position, abut the cutting part of the tool against the abutting part 53. The cutting part is perpendicular to the cutting medium 4, and the cutting part is aligned with the marking line 34 so that the cutting part is at the middle position of the cutting medium 4. Slowly press down the tool with a pressing speed less than 10 mm / s. As the tool gradually sinks, the downward pressure applied to the cutting medium 4 is transmitted to the cutting medium tooling 3, and the specific value is detected by the pressure sensor 23. When the cutting medium 4 breaks instantaneously, the control panel 2 will record the peak value of the sharpness. Thus, the tool detection step is completed.

[0055] If the cutting part touches the bottom of the cutting groove 31 at the instant when the cutting medium 4 breaks, the detected value of this time will be invalidated and re-detection is required.

[0056] The tool needs to detect three parts of the cutting part, namely the front, middle, and rear. The average value of the values obtained from the three is taken as the test result.

[0057] Through the above design scheme, the product can achieve the advantages of being portable, improving the detection efficiency, and being economical to use.
