“…Its alteration makes it possible to produce a tool with the flute shape, as close as possible to required. Literature is using algorithms to solve both the direct [32][33][34][35] and the inverse problems in profiling the helical flutes [36][37][38][39][40][41][42][43][44]. Simulating relative positions of the profiling tool and of the workpiece is basically performed in AutoCAD, NX, and CATIA environments [45][46][47][48].…”

This research was performed on the technological feasibility of manufacturing the multiple thread milling cutter flutes based on their mathematical and experimental simulation and studying possibility of manufacturing a prototype thread milling cutter with use of grinding wheels of typical profiles. System of mathematical expressions was developed to determine the flute end section profile produced by a grinding wheel and taking into account kinematic scheme of the multi-axis CNC tool grinding machines using the Walter Basic kinematic scheme as an example. Proposed mathematical expressions were approved by experimental studies when machining helical flutes on caprolon workpieces with a diameter of 34.5 mm with use of a universal grinding machine. Flute profiles comparison in the end section (experimental and calculated) showed their satisfactory convergence; the errors (up to 0.42 mm) could be explained by inaccuracy in grinding wheel installation, workpiece yielding, error in the experiment parameters settings and increasing discrepancy in the error measurement direction to the core diameter. To study technological feasibility of the thread milling cutter flutes manufacturing, the CoroMill Plura R217.15-140100AC26N thread milling cutter was choosed as a prototype. End section of the tool was obtained by a plane passing through the top of the tooth, and installation parameters for the grinding wheel type 1V1 were assigned using a developed mathematical expressions system. It was established that the grinding wheel type 1V1 made it possible to assign installation parameters required in fluting of the prototype. The possibility of choosing the grinding wheel profile and geometric parameters as well as its installation parameters based on the manufacturing simulation of the prototype performed in Walter Helitronic Tool Studio was confirmed, which makes it possible to perform thread milling cutters production technological preparation using the developed mathematical expressions.

“…Its shape and corresponding parameters are shown in Figure 1(b), which is composed of two single Y-shaped welding grooves located on two workpieces separately. Currently, cutting a single Y-shaped welding groove has generally four ways: milling, 3 planning, laser beam cutting 4 and flame cutting. 5 The principle of the former two is that remove extra materials directly via mechanical cutting, while that of the latter two ways is making use of high temperature to fusion and remove extra materials, in which tools do not touch workpiece directly so that jigs are unnecessary to fix workpieces.…”

To guarantee the strength and precision of the final welding assemblies, it is necessary to cut welding grooves before welding thick workpieces. General methods to cut welding grooves on plane workpieces need much manual assistance, and some even need manual operation purely. Therefore, this paper proposed a robot system for cutting Y-shaped welding grooves with full automation. Flame cutting technology has been adopted, requiring no jig to fix workpieces, which also causes no direct vibration to robot structure. Vision-based sub-system firstly captures the edges to be cut, which are composed of continuous points, and a laser range finder (LRF) starts to obtain the thickness of the edges precisely. To convert these edges into the trajectory of flamer, Least Square Method and Hermite Interpolation are respectively utilized to fit lines and curves. Robot system subsequently computes the motion-related parameters according to the position of the edges and geometric parameters of the desired welding grooves. The inverse kinematics of this robot is solved by geometry methods, which decreases computation burden and saves much time compared with traditional algebra method. Another core novelty is that a velocity planning method combining optimization algorithm has been put forward, which, we think, is not only useful in this gantry robot but also benefits other motion axes with heavy load. This further reduces vibration. Finally, the simulation and experimental results both prove the feasibility of this system. To date, no available robots or machines tool can finish this process with full automation (to the best of our knowledge).
