| Abstract | ||
| ABSTRACT In this research a flame of CNC cutting machine was used. It works manually only in straight line cut. All experiments had been done to reach a proper ultimate processing conditions for clean cut. The dwell time of preheating, piercing and the speed of cutting are variables - in addition to gas pressure - control the cutting process. The target was to improve cutting conditions of carbon steel metal of thickness arranged from (10–15) mm, then to design a written program to be fed with the final readings to the CNC machine to produce a complex frame having sections of straight lines, curves and right angles with tolerance of 0.1mm. The value of cut width which was (2) mm would be shifted toward the core dimensions according to the program. By this technique, it is capable to produce complex shapes such as gears, in particular big components having a clean and even cut for applications require less accuracy. | ||
