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. . CNC machine tool work offset . ISO-230-6, Test code for machine tools Part 6: Determination of positioning accuracy on body and face diagonals (Diagonal displacement tests) - First edition. This new automated compensation method is based on the offline part dimensional measurements in a CMM; it estimates the offsets in the WCS (Work Coordinate System) to compensate the machine tool errors including the fixture and table/pallet errors together with the tool length, some of the dynamic errors due to part clamping, tool deflections .
For manually operated machine tools, the accuracy of the machine tool structure limits the accuracy of the parts produced. Such is not necessarily the case with computer numerically controlled (CNC) machinecompensation implementing on machine tools with Siemens 840D CNC systems, which communicates with CNC system by the DRF offset function and substitutes for electronic

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.
