IntroductionThe use of computers to model complicatedsets of data into a sensible form is a concept thatdates back to at least 1 960 .This idea evolved into“scientific visualization”a broad term encompass-ing the use of various techniques for the represen-tation of scientific data in a more easily under-standable format,such as3D plotting.Advancedcomputer graphics,in conjunction with auditoryand haptic feedback channels including tactile dis-play methods,are common tools for achieving suchco… 相似文献

“一面两孔”组合定位是夹具设计中最和的定位方式之一,其定位误差由移动定位误差和转角误差组成。笔者经过多年的理论研究和实践探索,根据误差产生的原因和两咱定位误差在加工中所占比例的大小,总结出涨心式圆柱销与菱形销组合定位,圆柱销与模拟式菱形销组合定位、主式圆柱销与模拟菱形销组合定位三各定位方式,有效地提高了“一面两孔”组合定位的精度、特别是有模拟式菱形销的组合定位,在提高定位精度的同时,还可以降低工件 相似文献
