检测形位公差
ZEISS INSPECT中的几何尺寸和公差计算
什么是形位公差？
形位公差可以确定和评估部件的几何偏差。它们描述了与部件标称状态的最大允许偏差。如超出形位公差范围，则不符合部件的功能、配合精度或形状要求。例如，公差可用于确定钻孔是否完全吻合、方向是否正确或现有的形状误差是否在允许范围内。形位公差用于设计、生产和质量控制等工艺链的所有步骤。
形位公差偏差的可能原因包括：
- 加工过程中的变形
- 工具的磨损
- 机器振动
- 加工过程中的温度波动
ZEISS INSPECT中的形位公差功能
形位公差用于规范设计，同时也帮助计量人员验证部件。高效评估的基本前提是光学测量技术生成的全场测量数据。ZEISS INSPECT包括多个形位公差功能，可通过基准系统、拟合元素和公差对尺寸、形状和位置进行综合分析。此外，ZEISS INSPECT的参数化设计还支持和促进了形位公差分析。对于测量和分析单个元素来说，这意味着每个元素只需构建一次，然后就可以用作参考。相应的的计算方法会自动进行设置。
