METCUT - A Computer Aided System for Machining Technology

摘要

This report describes a package of computer programs which has been developed for providing appropriate cutting data for a number of machining applications. The whole package was written in BASIC and can be run on PDP 11 computers running under RSTS operating systems. At present the package can provide cutting data for 9 operations, namely turning, face milling, end milling peripheral, end milling slotting, drilling, tapping, boring, part off and form tools and threading. Operations can be added or deleted from the package as desired. This package is also linked to TKDRAW which is an AEL developed CAD/CAM package for turned components. The package has also been implemented on a DATA GENERAL MV4000 computer, running under a AOS/VS operating system, at the Regency Park Community College. The recommended cutting conditions for the various operations, based on the Machining Data Handbook, represent a tool life of approximately one to two hours of cutting time for most of the common alloys when using high speed steel tools. A tool life of 30 to 60 minutes is applicable for indexable-insert carbide tools. Additional keywords: Australia; Machining Information Data File; and editing.
