数控加工工艺中英文对照
（1）加工中心机床是机床中自动化程度较高、工序较为集中的机床之一，应用传统的夹具使加工中心的优越性很难发挥。
Machining center is one type of machine tools having high automation and preforming more operations.But it is difficult to bring the advantage of machining center into play with traditional fixture.
（2）工艺路线决定每个产品的有效工序。
The routings determine the operation sequence to do for each manufacture.
（3）刀具进给率是工件每转一周，刀具进入工件的速率。合适进给量的选择取决于许多因素，如要求的表面粗糙度、切削深度和所采用的刀具几何参数。
Tool feed is the rate at which the tool advances into the work per revolution of the work.The selection of a suitable feed depends upon many factors，such as the required surface finish，the depth of cut，and the geometry of the tool used.
（4）当零件有较大的平面可以作定位基准时，先将其加工出来，再以面定位孔加工，这样可以保证定位准确、稳定。
When the parts have bigger plane can make positioning base，its processing out first，then to face positioning hole processing，so that we can ensure accurate and stable.
