PRODUCTION OF APPROACH ROUTE OF NC WORKING MACHINE

摘要

PURPOSE:To simplify the production of data by adding adversely the coordinate data including the Z coordinate value and the X and Y coordinate values obtained at each cutting point from the cutting start point. CONSTITUTION:The machining allowance value of a work, the tool diameter data and the tool cutting route data are supplied to a computer memory 1. Thus an approach height/length arithmetic means 2 operates the height a1 and the length a2 of the approach from the machining allowance (f), the tool diameter (d), the safety factor (n), etc. Then an approach data giving means 3 gives the approach data Q1 and Q2-QN based on the cutting route data, the height a1 and the length a2. These approach data are given adversely to the front of a cutting start point P1 of the cutting route data via an approach data giving means 4 and then sent to an output medium through an output means 5. In such a way, an approach route tracing adversely a cutting route is obtained. Thus, it is possible to secure the sure approach to an NC working machine with no interference with obstacles.
