Abstract: A support mechanism includes a fixed body, a rotating unit, a moving unit and a driving unit. The rotating unit is rotationally mounted to the fixed body. The moving unit, disposed at the fixed body, includes a ball screw spline shaft, a ball screw nut and a ball spline nut. The ball screw nut and the ball spline nut are both rotatably disposed at the ball screw spline shaft moved together with the rotating unit. The driving unit, disposed at the fixed body, includes a first driving member and a second driving member to rotate the ball screw nut and the ball spline nut, respectively. With different rotation pairs of the ball screw nut and the ball spline nut to the ball screw spline shaft, the ball screw spline shaft is driven to move, and the ball screw spline shaft is further to move the rotating unit.

Abstract: A process-orientated design method for machine tool structures comprises the steps of: (A) Defining design conditions including initial configurations, cutting requirements and boundary conditions for the machine tool; (B) Calculating cutting ability to generate information realizing a relationship between a maximum cutting depth and a spindle speed of the machine tool based on the initial configurations and the cutting requirements; (C) Performing an optimization to generate a frequency range for optimization based on the information relating the maximum cutting depth and the spindle speed; (D) Performing structural topology optimization to generate an optimized model based on the frequency range for optimization, the initial configurations and boundary conditions; and (E) Determining whether the optimized model fits the constraint condition; if positive, ends the design steps, and otherwise repeats steps (B)˜(D) until an optimized model fits the constraint condition appears.

Abstract: A structural topology optimization design method is provided. A structural topology optimization question is defined to determine at least one set of load and restriction condition and a parameter of lower limit of volume capacity related to a design space model. This model is divided into mesh grids for performing finite element analysis (FEA). Strain energy of each element after FEA is obtained according to the established load and restriction condition and used as a basis for calculating sensitivity of each element. A part of elements is removed or retained according to the degree of sensitivity of each element, and the structural profile and the total volume capacity and total strain energy of residual elements of the structural profile are recorded after each loop was completed. A display interface is used to sequentially show the structural profile and a relationship diagram of structural volume capacity vs structural strain energy.

Abstract: An adjustable workpiece support system includes an adjustable support apparatus, an analysis support point module, a coordinate post-processing module and a control module. The adjustable support apparatus has a group of support devices for supporting a supported workpiece, the each support device being adjustable in height and angle. The analysis support point module is used to import a computer-aided design file of the supported workpiece, and analyze the computer-aided design file to obtain a group of support points of the supported workpiece. The coordinate post-processing module is configured to calculate the support coordinates of the each support device corresponding to the group of support points. The control module is configured to receive the support coordinates of the each support device, and adjust the height and angle of the each support device to support the supported workpiece, so that the amount of deformation of the supported workpiece is the minimum.
