本文之目的為設計一部鋸片自動加工機，使之具有可程式化、多層鋸片自動加工、自動檢測與補正等功能，以滿足工業界對鋸片產品的高附加價值需求。
目前工業界所生產的鋸片成品，其齒形將因使用時機及用途不同而有多種設計方式。本鋸片自動加工機乃針對用於金屬切削之鋸片而設計，此類鋸片之齒形採交錯式，故需依其齒形特徵建立一套齒形自動加工流程。由於此型鋸片亦具有高銳利度、高硬度與高精度的特性，為達成此需求乃採用磨輪研磨方式加工齒形，磨料為硬度極高之氮化硼(CBN，Cubic Boron Nitride)。同時為提高加工品質及磨輪的使用率，將利用影像處理方法，監測工件被加工時之鋸齒形狀與磨輪的損耗程度，以達到線上自動檢測與補正之目的。在產能方面，為提高產量乃設計一次可加工多片工件（既多層鋸片加工），故在機構設計上將異於一般的單片加工，而採連桿、滑塊與彈簧相互制動方式，使每片工件的被切削位置不因製具的轉動而偏移。
本加工機若研發成功，不但能提高產能打（與單片加工機比較，約可提高五倍之產量）更能降低人力之需求與製造成本。同時也能提高鋸片的加工精密度、銳利度與硬度等附加價值，並具有可程式化功能以生產出各式規格產品，以符合少量多樣需求。

The purpose of this thesis is to design an automatic saw-making machine which has the functions of automatic multiple parts saw-making, automatic detection and automatic compensation to satisfy the customer's necessities about high quality of saw production.
At present, the finished products of saw in industry, there are more different teeth shapes were designed to support the different purpose. In this automatic saw-making machine, the design method is focused on the saw that used on metal cutting. As the type of this saw, those teeth shapes are "alternating", we should follow the necessity of the teeth shapes to set up an automatic saw-making process. In order to succeed this saw's characteristics of the high sharpness, hardness and accuracy, we adopt the saw-making method of wheel grinding and use higher hardness material of CBN (Cubic Boron Nitride) for wheel. At same time, in order to reach the purpose of auto-detected and compensated on line, we utilize the theorem of image processing to monitor the teeth shapes of saw and wear out status of wheel during saw-making process. Regarding of the capacity promoting of production, the process of multiple parts saw-making is necessary, naturally, the organization design of this machine is different the other one part saw making machine.
If the machine will be developed successfully, the effects not only increases the production(compare with one part saw-making machine, the production could be promoted a multiple of five approximately) but could decreases the manpower and manufacture cost. At same time, to improve the saw parts qualities of saw-making accuracy, sharpness and hardness, and has programming function to produce variable saw parts to tally with the necessities of less quantities and more types.
