In the actual manufacturing with NC machine, in order to check whether the parts design and the cutting route are right or not, generally it is tested by examing how the tool and work plane will move with the input NC programme and without an actual part. Once the movement does not match the prescribed process, there must be a change to the design graphics and the NC programme, and then test again, until the tested one matches the requirements. This inevitably leads to the waste of manpower and time, so it is necessary to make a computer simulation to realize the fastness and preciseness of the movement and path of the machine.

哈尔滨工程大学硕士学位论文实际数控生产中，为了验证图纸的设计及其工艺路线是否正确，在正式加工前，经常让机床在输入编制好的NC程序后空载运行，以观察刀具及工作台是否能按预期的要求运动，一旦不合乎要求，则须反复对程序和图纸进行修改，这势必造成人力、物力的浪费，因此有必要对刀具和工作台的运动过程及其轨迹进行仿真，以便及时、准确地进行正式加工。

The method solves the problems better through adopting the following technical proposal that: the method takes the solid super acid consisting of the VIB group elements or the VIB group elements and the IVB group elements in the periodic table of elements and loaded on a symbiosis molecular sieve as catalyst, and naphtha with the component being C4-C10 as a raw material so as to carry out catalytic cracking reaction at a temperature of between 550 and 700 DEG C, under a pressure of between 0.01 and 0.5 MPa, at a reaction weight space velocity of between 0.1 and 4 hours and with the weight ratio between water and naphtha of between 0.5:1 and 4:1, thereby generating ethylene and propylene.
