Title: Tool path control system
Inventor: OTSUKI TOSHIAKI
IPC: G05B19/4093
Filed: 1992-12-02
Abstract: PURPOSE:To perform the corner machining without generating any machining error even if a tool moved along a corner circular arc. CONSTITUTION:A preprocessing arithmetic means 42 reads both blocks set right before and after a corner out of a corner part machining program 41 and outputs the corner part processing information to a tool path corrector means 44. The means 44 reads the radius R of the tool out of a memory 45 and also applies the offset to the tool path set based on the corner part machining information by an extent equal to the raius R. Thus, an offset tool path is obtained. At the same time, a shift correcting amount of the tool is calculated from a corner circular arc tool path obtained by connecting a point where the offset tool path corresponding to the block set right before the corner is extended toward the path by a prescribed distance to a point where the offset tool path corresponding to the block set right after the corner is extended in the opposite direction to the path by a prescribed distance. The tool moving along a corner circular arc is completely separated from a work. Therefore, a machining error is never generated at a corner even if a servo motor or a machine has a follow-up delay.

Title: Aluminum or aluminum alloy material
Inventor: IWAMA TETSUJI
IPC: B60B3/04
Filed: 1987-12-23
Abstract: PURPOSE:To improve the brightness and corrosion resistance of the title Al- material and the adhesive property of a film by forming the hardened film of Si-O in specified thickness on the surface of an Al-based material incorporated with a phosphorus-based compd., copper, and Ga. CONSTITUTION:A hardened film consisting of Si and O is formed at about 5-300mg/dm<2> on the surface of an Al or Al alloy material incorporated with a phosphorus-based compd.,copper element, and/or Ga element to form the Al or Al alloy material. Since the same smoothness as a Cr plating is imparted to the Al or Al alloy material, brightness is obtained, the corrosion resistance is equivalent to that of the ordinary anodic oxide film having about 10mu thickness, and hence the hardened film is not released even by repeated stress. Furthermore, the appearance, weatherability, and heat resistance are improved. Although the hardened film can be formed by various methods, a soln. or dispersion of an org. silica compd. in an org. solvent such as ethyl alcohol, for example, is applied on the surface of an Al alloy material coated with a phosphorus- based compd., and the material is baked under the conditions where a decrease in the mechanical property of the base material is controlled to <=10% as compared with the base material before heating.
