摘要:
For the function of forming numerical control information prior to machining process, the type of machining (such as drilling, end milling, outer diameter end face, etc.) and machining scope for each machining area is determined by inputting the shapes of a work and a part determining the machining areas based on said shapes, identifying the areas for inner diameter machining out of said machining areas, extracting from said inner diameter machining areas those characteristic areas to the inner diameter machining such as the area where a rear end face exists on the part shape, where a through hole is unprocessed or where a through hole is bored on the work based on the shape elements. As this method does not require preliminary reviewing of the machining method for inner diameter (and especially for small diameter), it allows beginner operators to produce numerical control information as easily as a skilled operator.
摘要:
A numerical control information generating system allows an operator to revise using a simple input method any of the types of machining steps, tools to be used and scopes of machining of a machining process which have previously been automatically decided according to certain criteria. Once a part shape and blank shape have been inputted, the system can fully utilize the knowhow of the operator without being restricted by detailed data of the shapes.
摘要:
In a method for determining a groove machining process based on numerical control information generating functions, a groove machining process is automatically determined based on characteristics of shape elements adjacent to groove shape elements as well as the shapes of the groove shape elements. The groove machining process can therefore be easily optimized.

The invention provides an alkali-soluble adhesive agent characterized by comprising an alkali-soluble resin that is a reaction product (C) obtained by allowing a polycarboxylic acid and/or a polycarboxylic anhydride having two or more carboxyl groups to react with a reaction product of a compound (A) having at least one epoxy group with a monocarboxylic acid compound (B). Preferably, the alkali-soluble resin is used in combination with a ketone organic solvent, optionally with at least one member selected from the group consisting of a melt viscosity reducing agent, a surface active agent and a plasticizer. The alkali-soluble adhesive agent can be removed by an alkali aqueous solution without recourse to any organic solvent, and is of an environmental protection-conscious type with improvements in adhesion, adhesion strength, coatability, surface smoothness, softening point controllability, melt viscosity controllability and spread controllability.

To provide a corrugated tube and an apparatus for and method of perforating a corrugated tube, which are capable of rapidly discharging water, such as water intruding into the inside and condensation water, to the outside and in which a plurality of communication holes can be positively and efficiently formed respectively in predetermined portions of a peripheral surface of a tube body. For example, a wire harness or the like is inserted into a corrugated tube 10 through a slit 12 formed in a tube body 11 of a tubular shape along a generating line of the tube body, the tube body having larger-diameter portions 20 and smaller-diameter portions 30 which are arranged alternatively along the same axis. Usually, the corrugated tube 10, receiving the wire harness therein, is installed in such a manner that the slit 12 is disposed at a lower side, but there arises the case where the slit 12 can not be disposed at the lower side because of the installation direction and a change of the direction. In such a case, any of communication holes 13 which are formed in that portion of a peripheral surface disposed the remotest from the slit 12, and communicate the inside and outside of the tube body 11 with each other is located at the lower side, so that water intruding into the corrugated tube, condensation water, etc., are discharged.
