Research on tool condition monitor instrument during milling special spiral rod;

Tool wear model is presented by firstly extracting power signal eigenvalue through tool wear analysis of special spiral rod milling,and then establishing the mapping between the signal eignevalue and the tool wear value.

In the process of milling special spiral rod,a comparative analysis of all kinds of signals that indicate the state of tool wearing has been made.

This paper analysises problems of the adaptive control of special spiral rod processing,brings forward an adaptive control system taking mental removal rate (MRR) as input,the vibration strength as output,establishes a method to caculate the MRR in processing and identifies the system and obtains the reference model based on the collection and disposal of vibration signal.

Analysis of the contact-track of multi-axis envelope milling abnormal spiral-rod

Study on multi-axis non-instaneous envelope milling abnormal spiral-rod

A mixing performance analysis on the different screw configuration in the process of twin screw codirectional extrusion;

The filling ratios in the main reactive zones were estimated by clam barrel for different screw configurations.

The mixing performance of different screw configurations of a co-rotating twin screw extruder and the grafting reactive extrusion of PE-LD-g-MAH were investigated.

The effect of main screw parameters (length/ diameter ratio, helix angle, channel depth and compression ratio)of cold feed rubber extruder on extrusion temperature were investigated by orthogonal regression method on the basis of the statistical analysis of experimental results.
