Offset Curve

Abstract This paper proposes a new method which generates offset curves used to obtain NC machine tool paths. A basic idea of the method is to utilize a called offset curve zone where the offset curves of each side constituting the profile of workpieces are generated. Using this method, we can generate the offset curves without being conscious of unnecessary offset curves often appeared in use of other methods and efficient tool paths because there are almost no overlaps of tool paths. For example, this method is applied to workpiece profiles consisted of the segments of straight line and circular arcs to generate the offset curves for tool paths in a two-and-a-half dimensional pocket cutting.

Wire Cutting

Based on the design theory of non-circular gears, using Pro/E drawing module, a system of elliptical gears parametric module and simulation was developed. Machining non-circular gear by wire cutting can be achieved by using Pro / E manufacturing module, and then gear machining tool path is created, tool and process parameters is set and simulation of process tool and process of post-processing analysis was described. Through the above process ultimately to generate post-processing procedures which NC machine tool need and achieve the automatic programming of non-circular gear. Form the application example, it has been observed that the gear created by Pro/E simulated NC programs can correct mesh according to the theory transmission ratio and the effectiveness of the proposed approach.

The estimation of accurate cutting time before cutting is important for improving productivity. Estimation of cutting time calculated by length of tool path / command feedrate can easily be obtained in commercial CAM systems because NC programs contain machining information, such as tool positions, feedrate, etc. However, the actual cutting time is longer than cutting time calculated by length of tool path / command feedrate due to acceleration and deceleration which occurs along the tool path. In this study, an estimation system of accurate cutting time based on the control system of the machine tool is proposed. Experiments were conducted to cut complex shapes using the NC machine tool to compare the actual cutting time, estimated cutting time of commercial CAM systems and those of the proposed system. The estimation error of the proposed system was only 2 %, while the estimation error of a commercial CAM system was 51 %.
