Abstract: The invention provides an in-site measurement method. The in-site measurement method comprises the following steps that S1, a sensor module (12) is mounted on a spindle of a machining tool of a machine tool; and S2, the spindle is driven, the sensor module (12) and a workpiece relatively move in a non-contact manner, the sensor module (12) scans the to-be-measured surface of the workpiece in the relative motion process of the sensor module (12) and the workpiece, therefore, the position information of the to-be-measured surface of the workpiece relative to the sensor module (12) is acquired, and then the size information of the to-be-measured surface of the workpiece is calculated and acquired based on the movement information of relative movement of the sensor module (12) and the workpiece and the position information, acquired by the sensor module (12), of the to-be-measured surface of the workpiece relative to the sensor module (12). According to the in-site measurement method, a geometric movement shaft of the machine tool is utilized for driving a sensor for scanning, wide-dynamic-range surface measurement can be achieved, and the beneficial effects of the high resolution and the large measuring span are achieved.
本发明提出了一种在位测量方法,包括以下步骤:S1、将传感器模块(12)安装在机床的加工工具的主轴上;S2、通过驱动所述主轴,使传感器模块(12)和工件无接触地相对运动;并在传感器模块(12)和工件相对运动的过程中,使传感器模块(12)扫描工件的待测量的表面,从而获取工件待测量表面的相对于传感器模块(12)的位置信息;然后基于传感器模块(12)与工件相对运动的运动信息和传感器模块(12)所获取的工件待测量表面的相对于传感器模块(12)的位置信息,计算获得工件的待测量表面的尺寸信息。本发明的在位测量方法利用机床的几何运动轴带动传感器进行扫描,可实现大动态范围表面测量,具有高分辨率和大测量量程的特点。
