1. Problem to be Solved: The stroke accuracy of molds directly determines the standard quality of the manufactured products. As the mold industry pursues internationalization and standardization, more precise measurement of mold stroke accuracy has become an urgent requirement. 2. Solution: Adopt a coordinate measuring machine (CMM) and apply the industry's most advanced spatial coordinate method to calculate the mold stroke accuracy. 3. Data Analysis Value: The spatial coordinate method enables more accurate measurement data for mold stroke accuracy, which helps to enhance the domestic mold industry's discourse power in formulating industry standards. 1. Randomly select molds produced by the tested horizontal machining center (HMC) from the production lines of enterprises related to the Mold Expo City as samples, record the XYZ three-axis stroke of the machine tool, and measure the precise XYZ three-axis coordinates of the sample molds using a coordinate measuring machine (CMM). 2. Calculate the spatial deviation conversion coefficient of the test via the spatial vector method. The specific algorithm is: Use the precise XYZ three-axis coordinates of the sample molds and the XYZ three-axis stroke of the machine tool to calculate the spatial deviation ratio σ through the following formula: σ = √[(X1-X2)² + (Y1-Y2)² + (Z1-Z2)²] ÷ √(X2² + Y2² + Z2²), where X1, Y1, Z1 represent the precise XYZ three-axis coordinates of the sample molds, and X2, Y2, Z2 represent the XYZ three-axis stroke of the machine tool. The result shall be accurate to the 4th decimal place. 3. Calculate the spatial deviation coefficient ζ of the horizontal machining center. The specific algorithm is: Deviation coefficient ζ = k × σ × 100%, where k is the conversion coefficient. 4. Compare the spatial stroke deviation coefficient ζ with the specified calibration value of the spatial stroke deviation coefficient. The test can only be passed if ζ falls within the range of the calibration value.
