Video工具機檢測和驗收測試測量系統
工具機性能，例如是否符合公差、表面形狀等，基本上取決於機床運動元件的動態和靜態精度。因此，對精密機床，必須測量和補償運動偏差。機床檢測指南和標準（ISO 230-2，ISO 230-3和ISO 230-4和VDI/DGQ Directive 3441）規定了動態和靜態偏差的測量方法。工具機常規檢測和驗收測試基本上只限於機床無負載時的幾何結構，對數控機床只限於測量定位的精度。由於加工結果取決於輪廓路徑和高加速度時的動態偏差，因此需要檢測加工零件尺寸精度以確定機床的動態性能。現在，海德漢的KGM 和VM 182測量系統可以直接測量動態和靜態偏差情況。這種直接檢測方法較只測量加工結果的優點是它能區別機床本身的影響和能區分不同影響因素。
Conventional inspection and acceptance testing of machine tools has been limited essentially to static measurement of the geometrical machine structure without load and on controlled machines to measuring positioning accuracy. Since the results of machining depend increasingly on dynamic deviations from the nominal contour and on high accelaration in the machine tool, the finished parts are also inspected for dimensional accuracy in order to draw conclusions about the dynamic behavior of the machine. The HEIDENHAIN measuring systems KGM and VM 182 can now be used to directly measure both dynamic and static components of deviation. The advantage of this direct inspection method over inspecting only the results of the machining lies in its separation of technological influences from machine influences, and in its capability of distinguishing individual factors of influence.
Dynamic measurements - especially at high traversing speeds -provides information on contouring behavior that permit conclusions about both the condition of the machine tool as well as the parameter settings of the control loop consisting of the CNC control, drives, and position feedback systems.
Static measurements - such as the measurement of position deviations in the linear axes using a comparator system - permit conclusions exclusively about the geometric accuracy of the machine.
Machine tool builders use the results of machine accuracy inspection for the purpose of making design improvements to increase accuracy. Such measurements also help them to optimize the commissioning parameters of the control loop wherever they influence the accuracy of a CNC machine.
Machine tool users can use these measuring systems for acceptance testing and regular inspection of their machine tools.
