测量效率是三座标测量机的一项经济指标,而三座标测量机的特点之一正在于运用新的测量技术,在保证一定精度的前提下,对难于测量或测量效率很低的大型或形状复杂的工件进行高效率测量。初期的测量机,其测量结果实现数字显示,但数据记录和运算处理的过程,仍占整个测量时间的30—50%。自小型电子计算机用于测量机以来,测量过程又向自动化跨出了一步。带计算机的三座标测量机不仅能对从简单的误差计算直到复杂的诸如误差统计分析的数据快速运算处理,并把处理结果输给显示部分,由电传打字机打印记录,同时又可以根据测量数据制备和修正数控机床使用的穿孔带,既提高测量效率,又扩大了测量机的用途。表7—1为一般座标测量机与带小型电子计算机的效率对比。
Measuring efficiency is an economic indicator of CMM, and one of the characteristics of CMM is the use of new measurement techniques, to ensure a certain degree of accuracy under the premise of difficult to measure or measure very low efficiency of large Or complex shape of the workpiece for high efficiency measurements. The initial measuring machine, the measurement results to achieve digital display, but the data recording and computing process, still account for 30-50% of the entire measurement time. Since small electronic computers have been used in measuring machines, the measurement process has taken a further step toward automation. The three-coordinate measuring machine with a computer can not only process data from simple error calculation up to complex statistical analysis such as error statistics, but also output the processing results to the display section, print the record by teletypewriter, and at the same time, Data Preparation and Correction The perforated tape used on CNC machines not only increases the measurement efficiency but also expands the use of the measuring machine. Table 7-1 compares the efficiency of a general CMM with a small computer.
