Highspeed, high finish machining technology can raise the efficiency greatly, improve the quality and grade of products, shorten production cycle and improve the market petition ability. For NC processing, either manual or automatic programming, the programming before going through the process analysis of the parts processing, processing scheme worked, choose a suitable tool, determine the amount of cutting, some process problems (such as a knife point, processing route etc) also need to do some processing. And control the accuracy of the method in the process, to produce qualified products. According to the characteristics of CNC, the specific parts, analyzes the process scheme, the scheme determination of tooling, cutting tools and cutting parameters selection, determine the processing order and processing line, NC programming. Through the process of making the whole process, fully embodies the CNC equipment to ensure the machining accuracy, processing efficiency, the advantages of the simplified procedures. Keywords: process analysis, process scheme, the feed line, control size. 畢業(yè)設(shè)計(jì)（論文）報(bào)告紙 IV ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 目 錄 第 1 章 概述 ............................................................................................................................ 1 數(shù)控機(jī)床的發(fā)展 .......................................................................................................... 1 數(shù)控機(jī)床分類及數(shù)控加工的特點(diǎn) ................................................................................. 2 第 2 章 零件的介紹 .................................................................................................................. 5 零件圖 ........................................................................................................................ 5 零件的技結(jié)構(gòu)分析 ...................................................................................................... 6 零件的加工過(guò)程 .......................................................................................................... 6 第 3 章 零件工藝分析 .............................................................................................................. 8 零件圖的分析 ............................................................................................................. 8 零件工藝過(guò)程分析 ...................................................................................................... 8 切削用量的確定 ........................................................................................................ 12 工藝路線的制定與工序的劃分 ................................................................................... 12 走刀路線的確定 ........................................................................................................ 14 工藝卡片的制作 ....................................................................................................... 17 第 4 章 數(shù)控編程 ................................................................................................................... 20 數(shù)控系統(tǒng)介紹 ............................................................................................................ 20 數(shù)控程序 .................................................................................................................. 21 第 5 章 加工過(guò)程 ................................................................................................................... 24 機(jī)床的開機(jī) ............................................................................................................... 24 零件 的裝夾對(duì)刀 ......................................................................................................... 24 零件加工程序的輸入 ................................................................................................. 24 零件加工結(jié)果 .................................................................................
