Current tool path computation in the CAM algorithms approximates the surface by piecewise linear interpolation. In the case of three-axis machining on a CNC machine the tool will exactly reproduce.
Though this topic does not find mention in most undergraduate manufacturing engineering texts, except (Tlusty, 1999), it has a place in the modern manufacturing curriculum at the undergraduate level, being of utmost importance in manufacturing process equipment design.Here, we present a method which we have successfully used to introduce the subject .
machine tools, the compensation method has been the most effective approach to control part quality. This paper presents the development of a Global Offset compensation method utilizing the .Anik Manglik et al 130 configurations involve a double turntable which rotates the work-piece. An example is a θx –rotation of the part, followed by a θz –rotation, X-translation, Y-translation and a final Z-translation (RRTTT). Other common configurations are RTTTR and TTTRR.
The global offset for a machine tool is estimated through a model while utilizing the computed deviation between the measured and nominal dimensions of the part. Furthermore, the paper presents several other compensation concepts supporting the global offset method. The strengths and limitations of all compensation methods are also discussed.Semantic Scholar extracted view of "Global Offset Compensation for CNC Machine Tools Based on Workpiece Errors" by J. Gu et al. . and the essence of the offset curve is a method of path modification, which means that the general formula for offset compensation of plane curve is obtained through normalization. .

2.1 Configuration of a 5-axis machine tool. As depicted in Fig. 1, an XFYZBA-type five-axis machine tool with a universal head is considered in this paper, and it is composed of three linear axes (X, Y, and Z) and two rotary axes (A and B).It should be emphasized that the compensation method is also fit for machine tools with other structures. Different approaches have been applied to manufacturing face gears, including shaping, hobbing, grinding, cutting, etc. The shaping method was used as a theoretically fundamental way to design and manufacturing of face gears, of which the face gear tooth surface is usually designed as the envelope surface of a shaper cutter [3].Wang et al.
