The Detection and Analysis of Straightness Errors on Pillar and Guide Rail of Alien Stone Turning-Milling Compound Machining Center

Abstract

The alien stone turning-milling compound machining center is a new generation gap multifunctional compound machining center. It is used to process rotating part of alien stone products and three-dimensional sculpture products. The pillar and guiding rail are the key parts of the machining center. The straightness error of the pillar and guide rail seriously impacts the linear motion precision of beam parts. Comparison the straightness of guiding rail with pillar or without pillar, it shows that the results meet the standard of GB/T16462-1996. So it ensures the accuracy of the linear motion precision of beam parts. It lays a solid foundation for achieving the design function and machining precision.

Dynamic Testing and Fault Diagnosis of CNC Based on the Method of Cepstrum Identification

“…From the spectrum curve of main three directions we can also learn that, in addition to vibration amplitude increases one or two times, the largest peak point near to 2670 Hz and 4060 Hz, and the other frequency amplitude is small. The type is very similar with regeneration chatter features, when cutting chatter occurs, the vibration of main spindle -cutting tool system will be embodied in a frequency point [11]. Judging from this, the cutting process under this cutting parameter belongs to chatter cutting, but flutter body is not necessarily the main shaft.…”

Research on the Wear Characteristics of PDC Diamond Cutting Tools for Natural Granite

“…Tool wear vary depending on the size of grit wear surface of the tool, the quality of the workpiece surface and the cutting force. With increase of the grinding material in addition to volume, gradually increased tool wear, the literature [6] suggests that the tool wear can be divided into three wear period on the relationship between grinding material in addition to volume and tool wear.…”

“…Assumes that a single chip cross-section is triangular and the entire chip does not distort. dmax can be indicated by formula [6] .…”

Design and Analysis of a Sawing-Milling Compound Machining Center for Special-Shaped Stone Products

“…Stone's physical composition is very complex, and is apt to collapse while processing. So common diamond blades are not applied, and the sintered diamond tools, electroplating tools and brazing tools are usually used [2][3]. Fig.…”
