行程 1.(路程) route or distance of travel; distance of run; length of travel; distance travelled; journey; flight 艱難的行程 hard journey; 漫長的行程 long route; 行程五千多公里 travel over 5,000 kilometres; 一小時的行程 an hour's march; 這將是一整天的行程。it will make a full day's march.2.[機械工程] stroke; throw; travel 活塞行程 piston travel; 滑枕行程 ram stroke3.[電學(xué)] range
Platen backhaul height can be set in a random manner , therefore reducing the spare travel 壓板回程高度可任意設(shè)定,減少了空行程。
Rising positions of the platen can be set randomly to reduce spare travel and improve working efficiency 壓板回程位置任意設(shè)定,減少空行程,提高工效。
So the parameters , such as the vacant stroke and the welding velocity , can be modified and monitored at real time 可對空行程、焊接速度等參數(shù)進(jìn)行實時修改并監(jiān)控。
Simple and accurate settings of cutting depth and free settings for back stroke of pressure plate to reduve the idle motion and improve working efficiency 裁力深度設(shè)定簡單、準(zhǔn)確、壓板回程可任意設(shè)定,減少空行程,提高工效。
Shortening the motion ( migration ) distance of the cutting tool , reducing ( idle motion ) the spatial traeling schedule is the key consideration of choosing the numerical control turning processing route 縮短刀具的移動距離,減少空行程是選擇數(shù)控車削加工路線應(yīng)重點考慮的。

Secondly , to counter contour curve for large sole of rubber overshoes , the way of linear circle arc spline of two dimensions curve fitting has been raised in this paper and autocad has meanwhile been applied in cad / cam integeration system of rubber overshoes mould , and also a whole set of software and hardware technique developed , and the selecting way for optimizing tool path worked out . this way may make nc machining free running minimun 其次,針對膠鞋大底的輪廓曲線,對圓弧樣條進(jìn)行了深入研究,提出了二維曲線擬合的線性化圓弧樣條方法;同時將autocad應(yīng)用于膠鞋模具cad / cam一體化系統(tǒng)中,成功地開發(fā)了一整套相應(yīng)的軟硬件應(yīng)用技術(shù),提出了刀具軌跡優(yōu)化的動態(tài)選擇法,以便使nc加工的空行程相對極小化。
In the course of working , , the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right . compared to the unilateral plow , it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey . to meet the requests above , we will use a remote cylinder with both a small cubage and double functions , approximately designing the plow to be columniform and symmetric . after the experiment for a period in the field , we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly 與單向犁相比,其優(yōu)點在于:耕地?zé)o開、閉壟,地表平整,降低了耕后整地的能量消耗,減少了地頭的空行程,因而大大提高班次生產(chǎn)率。為了滿足犁體梭式作業(yè)的要求,我們采用了一只小容積雙作用的液壓油缸;同時對犁壁曲面的形狀采用了近似圓柱形的對稱設(shè)計。但經(jīng)過一段時間的田間試驗,我們發(fā)現(xiàn):該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴(yán)重;主犁梁和油缸缸體的連接部分(即油缸底座)突然發(fā)生了斷裂,造成整個犁體無法正常工作。
