数控滚齿机行程精度测量数据

1.问题背景：我国最新研发的DekayYS系列数控滚齿机，在世界处于领先地位，其各运动轴均由独立交流伺服电机驱动，采用展成法原理，通过数控系统电子齿轮箱（EGB）功能，实现分度和差动补偿运动，可实现圆柱直齿轮、斜齿轮、小锥度齿、鼓形齿、花键、蜗轮、链轮等齿部的加工。国内行业协会对于数控滚齿机的行程精度要求较高，且外贸企业所针对的海外客户及行业协会只允许将测量达标的数控滚齿机加工的模具列入进口清单，因此模具博览城需要测量数控滚齿机的行程精度。该测项目涉及到空间三坐标行程，传统测量器具难以满足要求，因此需要使用专业的测量数据进行计算。 2.解决方式：使用三坐标测量机测得模具产品的XYZ三轴精确空间坐标，并通过相应的算法转化成为该机床的空间行程偏差系数，与规定的空间行程偏差系数标定值进行比较，可判定其行程精度是否达标。1.随机在模具博览城相关企业生产线上抽取由被测数控滚齿机加工的模具作为样品，记录机床的XYZ三轴行程，并用三坐标测量机测得样品模具的XYZ三轴精确坐标。 2.运用空间向量法计算该检测空间偏差换算系数，具体算法：将样品模具的XYZ三轴精确坐标分别与机床的XYZ三轴行程，通过如下公式进行计算：空间偏差比σ=√[（X1-X2）平方+（Y1-Y2）平方+（Z1-Z2）平方]÷√（X2平方+Y2平方+Z2平方），其中X1、Y1、Z1分别为样品模具的XYZ三轴精确坐标，X2、Y2、Z2分别为机床的XYZ三轴行程，结果精确到小数点后第四位。 3.计算该数控滚齿机的空间偏差系数，具体算法：偏差系数ζ=k×σ×100%，其中k为换算系数。 4.将空间行程偏差系数ζ与规定的空间行程偏差系数标定值进行比较，必须在标定值范围内，才可通过检测。1. Problem Background: China's newly developed DekayYS series CNC gear hobbing machines are at the leading level worldwide. All motion axes are driven by independent AC servo motors, adopting the generating method. Through the Electronic Gearbox (EGB) function of the CNC system, indexing and differential compensation motions are realized, enabling the machining of cylindrical spur gears, helical gears, small tapered gears, crowned gears, splines, worm gears, sprockets and other tooth-shaped parts. Domestic industry associations have high requirements for the stroke accuracy of CNC gear hobbing machines, and overseas customers and industry associations targeted by foreign trade enterprises only allow molds processed by qualified CNC gear hobbing machines to be included in the import list. Therefore, the Mold Expo City needs to measure the stroke accuracy of CNC gear hobbing machines. This measurement project involves spatial three-coordinate strokes, which traditional measuring tools can hardly meet the requirements, so professional measured data is required for calculation. 2. Solution: Use a Coordinate Measuring Machine (CMM) to obtain the precise spatial coordinates of the X, Y, Z axes of the mold products, and convert them into the spatial stroke deviation coefficient of the machine tool through corresponding algorithms. By comparing with the specified calibration value of the spatial stroke deviation coefficient, it can be judged whether the stroke accuracy meets the standard. 1. Randomly sample molds processed by the tested CNC gear hobbing machine from the production lines of enterprises related to the Mold Expo City as test specimens, record the X, Y, Z axis strokes of the machine tool, and use the CMM to measure the precise X, Y, Z axis coordinates of the specimen molds. 2. Calculate the spatial deviation conversion coefficient using the spatial vector method. The specific algorithm is as follows: Calculate using the precise X, Y, Z axis coordinates of the specimen mold and the X, Y, Z axis strokes of the machine tool with the following formula: Spatial deviation ratio σ = √[(X₁ - X₂)² + (Y₁ - Y₂)² + (Z₁ - Z₂)²] / √(X₂² + Y₂² + Z₂²), where X₁, Y₁, Z₁ are the precise X, Y, Z axis coordinates of the specimen mold respectively, and X₂, Y₂, Z₂ are the X, Y, Z axis strokes of the machine tool respectively. The result shall be accurate to four decimal places. 3. Calculate the spatial deviation coefficient of the CNC gear hobbing machine. 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. Only when it is within the range of the calibration value can the test be passed.
