Glazing is a key procedure in ceramic product surface decorating processing. Recently, robots are gradually utilized to fulfill the glazing work instead of manual work. However, the researches on freeform surface glazing technology lag behind the research on robotics technology, thus limits the application of glazing robot in ceramic industry. In order to improve the quality and efficiency of robot glazing, this paper presents a new method which is base on STL model to generate trajectory for glazing spray gun. The whole procedures of this method have been discussed explicitly.

A new method for sampling meat surfaces using abrasive discs has been tested against the spray gun technique already described by Clark (1965). Evenly inoculated beef and pork slices were sampled after 1, 48, and 120 h of incubation at 4 °C for beef and 1, 48, and 72 h at 4 °C for pork. The new method was slightly less efficient than the spray gun in recovering bacteria during the early stages of incubation but was about 600% more efficient after 72 and 120 h.

In order to solve the freeform surface spray planning problem in spray industrial, this article proposed a model of the spray gun and description of the spray procedure. Then, the article presents a rapid planning method based on CAD model of the workpiece. With this method, the spray trajectory is constructed by the path points normal vector and S-shaped path using CAD model. In ABB's RobotStudio simulation software, a spray experiment is carried out. The simulation results show that this method can effectively simplify the offline planning process and save processing time.

Spray Gun

In the trajectory planning process of spray painting robot, an approach to automatic trajectory generation of spray gun using point cloud slicing is presented. Firstly, the point cloud data is obtained by scanning the surface of the workpiece. After the uniform slicing of point cloud model, the spraying position is determined by the average sampling of cross-section contours. Then the normal vectors of the sampling points are estimated. Finally the trajectory of spray gun is generated by offsetting the sampling points along their normal vectors. Experimental results show that the method has good feasibility and effectiveness. The spraying trajectory, direction and distance of spray gun can be controlled accurately, thus the spraying quality and efficiency are improved.

Definition Of

Freeform architecture places a high demand on its accomplishment. With today's technology a lot of individual and manual work is needed. By means of serial-production some challenges such as high costs and compliance of small tolerances can be handled. This results not only in issues in the field of manufacturing technology but also in the field of geometry.In order to simplify the manufacturing process a tool library with a defined minimum count of moulds is developed to map groups of surface elements on each mould. The Aim is to map any freeform surface with a clearly defined tool set based on an approximated curvature description.

Effective Design

This paper studies the performance assessment of magnetic-assistance electrochemical finishing using an effective design system and magnetic force to the electrolyte to assist the dregs discharge on zinc alloy beyond die casting by electrochemical finishing as a finish process on the freeform surface of castings. An outer shell of toy vehicle is taken for instance in the experiment. A small distance between the two magnets or large magnetic field intensity provides larger magnetic force and discharge ability. A higher current rating with magnetic-assistance can avoid the difficulty of dreg discharge, thus reducing the finish time. Pulsed direct current can slightly promote the finishing effect, but the machining time is increased. Thus the magnetic-assistance electrochemical finishing without pulsed current is recommended for the finish process. It is a great contribution that the magnetic-assistance electrochemical finishing just needs quite short to make the freeform surface of workpiece smooth and bright.

The study presents a new method for 5-axis machining of blisk, which consists of both roughing tunnels and finishing blades. The ruled surface is used to approximate the freeform surface of blade, and the boundary contour of the tunnel is then determined. Based on the double point offset method, the 5-axis tool paths for roughing blisk tunnel region are generated. Similarly, by linking the corresponding points on the tool center curves and the tool axis drive curves, the spiral tool paths are developed to finish milling thin-walled blades taking into account the residual stresses induced part distortion during machining. This strategy is experimentally verified.
