Abstract. The combination of trunnion type numerical control rotary table and three-axis machine tools can achieve the work of five-axis machine center. The key part of trunnion-type numerical control rotary table, trunnion, was studied by statics analysis, modal analysis and harmonic response analysis. The maximum deformation, vibration performance and other parameters, which may do harm to the accuracy, were investigated. Meanwhile, the dynamics and kinematics analyses of rotary table virtual prototype were conducted. The results of simulation and analyses provide theoretical basis and important references for the optimization design and manufacturing. Introduction In recent years, machine tools need better properties, such as high speed, high precision, high efficiency and complex, to meet the high processing requirements [1-3]. The common machine tools fail to meet these demands. So five-axis machining center will lead the development trend of machine tools. Numerical control (NC) rotary table is one of the key components for five-axis machining center, which can fix in the direction of rotation and swing. Xu et al. [4] investigated the structure characteristics of two-axis rotary table and the application of torque motors on it. Gu et al. [5] built a mathematical model of NC rotary table transmission system, and provided some methods to improving the dynamic performance of table. Jiang et al. [6] investigated the modeling and simulation of virtual prototype for five-axis machine tools with rotary table. However, they didn’t take statics, dynamics and kinematics problems into account synthetically and discover the intrinsic laws. So in this work, the designed NC rotary table was modeled by Solidworks, and the statics and dynamics analyses for trunnion were conducted by ANSYS workbench. Also, functions of rotary table virtual prototype were simulated and verified by Adams. Model and Parameters The overall appearance and internal structure of trunnion type rotary table are shown in Fig. 1. It has two degrees of freedom: the swing of trunnion and the rotation of table. The parameters are shown in Table 1. Table1. Performance parameters of the table. Main parameters Units Values Table diameter [mm] Φ600 Maximum table load [Kg] 160 A-axis rotation angle [°] -120°~120° C-axis rotation angle [°] 0°~360° Rated torque of rotation motor [N. m] 1750 Rated torque of swing motor [N. m] 3050 A-axis maximum locking torque [N. m] 4477 C-axis maximum locking torque [N. m] 3414 The swing torque motor can drive trunnion and swing base swinging in space. The direct-drive technology of torque motor eliminates all mechanical transmission mechanism from motor to rotary table, which achieves zero transmission. The locking devices are responsible for the location of swing base and table with inputting hydraulic oil.

Model of trunnion type numerical control rotary table. Statics and Dynamics Analyses of Trunnion Statics Analysis Trunnion is one of the key parts of rotary table, which combines base and swing section, so the statics and dynamics analyses on the trunnion model are very important. The loading limit of trunnion occurs in two cases. One is that when swing base stops at the limiting position (±90°), locking device provides locking force, and torque motor doesn’t output power. The maximum stress and deformation of trunnion concentrate on the contact area with locking device, at 12.32 MPa and 3.73×10-5 m respectively. The other one is that when swing base stops at limiting position and on the point of moving against the torque of swing section and workpiece, torque motor provides peak torque, and locking device is still locking. The maximum stress and deformation of trunnion are 12.22 MPa and 3.74×10-5 m respectively, and the concentration areas are similar as the first case. The deformation nephograms are shown in Fig. 2. (a) The first case (b) The second case Figure 2. Trunnion deformation nephograms in two cases. Modal Analysis Modality reflects the inherent attribute of mechanical structure. Modal analysis of mechanical structure includes modal shape, inherent frequency and damping ratio [7]. Modal analysis is the first step of other complex dynamics analyses, such as harmonic response analysis, spectral analysis, transient dynamic analysis, etc. The modal analysis of trunnion was conducted based on the statics analysis. Six lowest order inherent frequencies obtained by computing are 333.23 Hz, 490.61 Hz, 508.71 Hz, 534.59 Hz, 671.93 Hz and 672.8 Hz. The modal shapes of them are shown in Fig. 3. Figure 3. The modal shapes of six lowest order. In the first order modal shape, the axis region of trunnion vibrates under the effect of locking device. The edge of the axis region and plate region are more sensitive. In the second order modal shape, the axis region pulls back and forth from the plate region, and the center of plate region is more likely to be damaged. In the third and forth order modal shapes, the edge of plate region twists alternately, which is weaker than other areas. In the fifth and sixth order modal shapes, the axis region of trunnion swings up and down, and the top edge and lower edge of axis region may be damaged. For trunnion, the vibration source is rotation torque motor. The revolving speed of motor can increase with the drop of motor torque. The revolving speed range is 110 r/min~2000 r/min, so the vibration frequency range is 2 Hz~35 Hz, which is lower than the inherent frequency of each order. So it is unlikely to cause vibration for the operation of motor. Harmonic Response Analysis Harmonic response analysis can show the influence of exciting force on machining accuracy more clearly. Rotation torque motor could produce exciting force, which was like harmonic vibration generated by rotary unbalance mass. An exciting force was applied to trunnion along Y direction, which was estimated to 500 N and its phase angle was 0°. According to the results of modal analysis, the frequency range was set from 0 to 800 Hz including 50 substeps, i. e. computing response every 16 Hz. The frequency response curves in X direction, Y direction and Z direction obtained by computing are shown in Fig. 4 to Fig. 6. Figure 4. The frequency response Figure 5. The frequency response of X direction. of X direction. Figure 6. The frequency response Figure 7. Total deformation of 330 Hz. of Y direction. The simulation results show that the maximum amplitudes in X, Y and Z directions are 6.6×10-6 m, 5.1×10-10 m and 1.4×10-6 m, respectively. The maximum value occurs at 330 Hz in X direction, under which the total deformation was shown in Fig. 7. The center region of trunnion plate has the maximum deformation, so dynamic load and revolving speed should be adjusted to avoid resonance during machining. Kinematics and Dynamics Analyses of Virtual Prototype The kinematics and dynamics analyses of trunnion type rotary table virtual prototype were conducted by Adams, which could verify the feasibility of motion. The swing of trunnion and the rotation of table can cause the coupling of revolving speed, torque, etc. Ten fixed Joints, two revolute pairs and two cylindrical pairs were applied to the model in order to achieve the motion of rotary table in two degrees of freedom. Two drives were applied to the motion of swing base and the rotation of table respectively. Eq. 1 and Eq. 2 show the velocity functions. Three loads were applied to the Adams model, including gravity, torque on workpiece and torque on swing base. They could simulate torques on table generated by cutters. Time cos(( ) ) . (1) 222 Time cos(( ) ) 322. (2) Kinematics Simulation Analysis The angular accelerations of swing base and table are shown in Fig. 8 and Fig. 9. It can be seen that the curves are smooth, so the movement process of rotary table is stable. It meets the requirement of machining. Figure 8. The angular acceleration Figure 9. The angular acceleration of table. of swing base. Dynamics Simulation Analysis Fig. 10 shows the output torque of swing motor. The output torque peak is 2103 Nm only when swing base moves, and the value is 2103 Nm as well when the table revolves around two axes. In addition, they have the same trend, so coupled motion almost has no influence on swing motor’s output torque. Figure 10. Output torque of swing motor. Figure 11. Output torque of rotation motor. Fig. 11 shows the output torque of rotation motor.

    The premier source of parts and accessories for mini lathes and mini mills. Using a Rotary Table A rotary table can be used to make arcs and circles. For example, the circular T-slot in the swivel base for a vise can be made using a rotary table. Rotary tables can also be used for indexing, where a workpiece must be rotated an exact amount between operations. You can make gears on a milling machine using a rotary table. Dividing plates make indexing with a rotary table easier. Introduction The following illustrations show the various parts and controls of a rotary table.

  • Bill Wilson from Wilson Combat
    Meeting Our Suppliers; Bill Wilson From Wilson Combat The first thing that you begin to notice about Bill is his down-to-earth personality which is reflected in his approach to building reliable, self-defense pistols. My goal with this interview was to gain some personal insight into Bill’s early years as a pistolsmith, as opposed to his ability as a handgun competitor. The other thing I really wanted to know was what criteria he demands in a well made handgun. Hopefully, all of our readers can apply his thoughts and ideas to their pistolsmithing projects. I hope this interview brings Bill and his philosophy on defensive handguns, competition and business practices a little closer to home. I’d like to personally thank Bill for taking the time to talk with me. When did you begin pistolsmithing? I started tinkering with doing revolver action jobs as far back as 1972 and first began working on my own 1911 style pistols in 1974. The first 1911 I worked on for a customer was in 1977 and the customer was Frank Triplett of Licking, MO. What was the very first pistol or handgun that you built? A series 70 Colt .45 with the following modification: King-Tappan high visibility fixed sights, trigger job with long aluminum trigger, polish feed ramp and throat barrel, lower ejection port, polish and adjust extractor, bevel magazine well, bob hammer spur, Swenson ambidextrous thumb safety and Pachmayr grips. Is your pistolsmithing training formal or informal? Informal, I would say. My formal training is as a watchmaker/jewelry maker, and many of these skills, especially making clock parts and jewelry, were easy to apply to guns.
