چکیده:

The aim of this research is to improve the productivity of CNC machine tools by optimizing feed rate. To optimize feed rate two programs were used, ”ACIS” (with scheme language) and ”VISUAL BASIC”. The scheme program for modeling the work piece, tool, cutting edge and calculating maximum cutting force and the VISUAL BASIC program to control all the activities, linked to the ACIS program for estimating optimized feed values. Laboratory tests were conducted To verify the results from the modeling, using an insert type one flute ball-end cutter on a CK45 carbon steel work piece. No coolant was used throughout the experimental works. Comparison were made between the maximum cutting forces, in the ”fix” feed rate tests. The results indicate significant increases in productivity which can be achieved, by using the optimized feed rate method
