Abstract

The determination of a cutting tool's feed and speed for a material removal operation requires an exact knowledge of many variables influencing the correct selection. These variables are dependent upon the type of material to be cut, the type of machine tool to be used, and the type of tools and operation they are to perform.

Tool Feed and Speed

The determination of a cutting tool's feed and speed for a material removal operation requires an exact knowledge of many variables influencing the correct selection. These variables are dependent upon the type of material to be cut, the type of machine tool to be used, and the type of tools and operation they are to perform.

Each magnetic tape or disk file contains a complete and comprehensive description of data. File 1 contains material specification, file 2 contains machine parameters, and file 3 contains tool characteristics. The files can be originally loaded, modified, updated or listed by selecting command words.

Interrogation of the files for the purpose of determining the feeds and speeds of cutting tools can be accomplished three distinct ways. In the first method, use of command word FAST triggers a complete analysis of the material, machine and tools indicated by the requestor. The output indicates calculated feed and speed of each tool plus messages relating to program decisions and recommendations. For the second method, use of command word FASTEST results in similar calculations as for the word FAST but also determines a process time estimate. In the third method, use of command word FASTER also results in interrogated tool feed and speed output plus the following output.

Output A provides the complete descriptive geometry of the cutting tool. Output B, through display by cathode ray tube or plotter or both, provides the outlin...
