While information is currently available to the programmer about acceptable feeds and speeds, choices of these parameters do not radically affect the part program structure by altering the number of passes or tool. This work outlines the development of NC programming subroutines for use in generating the tool path for pocket milling operations in such a way as to avoid the occurrence of chatter. An end user is able to achieve the highest mrr when rough facemilling compared to other milling operations, but it's important to accurately calculate the power and torque requirements for a given machine tool to achieve the desired level of productivity. Application of Sandvik Coromant A345-102R38-13M cutters at the recommended cutting conditions requires a 30- to 35-hp machine tool. Then, the required machining power is calculated through the net power and the machine efficiency factor. First, the net power, or power at the cutter, is calculated. The required machining power is calculated in two steps. Calculations of the cutting force, torque and machining power requirements associated with these cutters are based on the tool geometry and the cutting data recommended by. Some popular cutters for facemilling steel made by Sandvik Coromant Co., and Kennametal Inc., are discussed.

As practical examples, this paper describes 3 types of ATASS for turning center, lathe, and machining center. By applying ATASS to machine tools, we can reduce the total cutting tool expense by 14-70% and cutting tool space by 20-75%. The new modular tool has cutting performance equivalent to that of the conventional tools. We also designed a new modular tool that is easy to assemble automatically, and in which coupling can be completed within 0.5 sec. This system consists of a magazine for the cutting edge, an assembly device, a supply device, and a controller. system and named it ATASS (R) (Automatic Tool Assembly and Supply System). It is suggtsted that an automatic assembly device for modular tools would be very useful, especially for machine tools with many cutting tools. However, the coupling of a cutting tool edge and a cutting holder is achieved manually and takes 5 to 10 min.

Modular tools have the potential to offer a more economical solution to the problem of designing FMS lines for machine shops.
