查询词典 lathe

Until 1935 the lathe was intended to be driven by round "gut" leather bands, a distinct disadvantage when heavier cuts were needed; Drummond, for example, had abandoned the round belt in 1921 and changed to an inch-wide flat, an option denied to Exeter Engineering by the compact nature of their drive system.

直到1935年的车床是打算轮驱动的&肠&皮革带，一个明显的劣势时较重，需要削减；德拉蒙德，例如，已经放弃了轮带，在1921年改为1厘米宽的平面，一个选项否认到埃克塞特工程的性质，其紧凑的驱动系统。

The outstanding feature of the new cutting dynamometer contrary to other type of dynamometer sensor is that it is more similar to general lathe tool. It can be installed on knife rest, so it is same wit practice state of cutting. Sensitivity of dynamometer is more high, especially main cutting force can attain 7.4pC/N. The calibration results show that it has high static linearity, and its natural frequency is greater than 5 kilohertz, so the cutting dynamometer has fully reached the dynamometer standard stipulated by CIRP-STCC.Finally, in order to measure the cutting force, the orthogonal experiment method in which the three factors are the diameter of cutting, feed and spindle speed is performed.
