본 발명의 동적 공구 마모 보상 방법은, 가공 프로세스 동안 공구에 작용하는 가공부하를 감지하고, 가공부하와 메모리내에 미리 등록된 공구 마모 특성을 기초로하여 공구의 마모량을 추정 계산하여, 그 마모량을 기초로 공구의 위치 보상량을 자동적으로 바꾸게 된다. 예를 들면, 기준 가공 전류값으로서 메인 스핀들의 부하 전류값을 취하는 경우에 단위시간당의 공구 마모량을 기초로 공구의 마모계수를 미리 산출하고, 그 기준 가공 전류값에 대한 실제 가공 프로세스중의 메인 스핀들 부하 전류값의 비와 상기 공구 마모계수의 곱을 가공시간에 대해 적분함으로써 공구의 마모량을 추정 계산한다. The dynamic tool wear compensation method of the present invention detects the machining load acting on the tool during the machining process, estimates the amount of wear of the tool based on the machining load and the tool wear characteristics previously registered in the memory, and based on the wear amount. The position compensation amount of the tool is automatically changed. For example, when the load current value of the main spindle is taken as the reference machining current value, the wear coefficient of the tool is calculated in advance based on the tool wear amount per unit time, and the main spindle in the actual machining process with respect to the reference machining current value. The wear amount of the tool is estimated by integrating the product of the ratio of the load current value and the tool wear coefficient with respect to the machining time.

Woodworking machine having a plurality of sequentially operative multiple tool units

Abstract Of The Present Invention A woodworking machine has a series of stations spaced along a conveyor having a clamp support for holding flat wood parts and passing the edges through the stations which include cope stations as well as others. The coping stations have a tool unit with a stack of tools mounted on a common spindle. The tools in each stack at the several stations are interrelated such that the cuts of the individual tools can be combined to form different final profiles in a wood part moving through the several stations. The particular cuts in the profile line are analyzed and interrelated to define basic cuts which can be combined to form the final profiles. One tool of each tool stack provides a particular cut, and by precise positioning of the individual tools, the combination of sequential cuts provide the final profile. Each tool may form a complete cut, may overlap a previous cut to form a continuation of such previous cut or may form a cut which includes only a portion of its cutting face. Computer aided design technology may be used. The machine significantly reduces the tooling costs by significantly reducing the number of tools and the complexity of the tools required for producing a product profile line. Each tool includes a support on the spindle with a cutting tip, many of which are basic presently used tips having flat edges and the like. The tool position control includes an absolute positioning system including a computer in closed loop control program. The control unit establishes precise orientation to form a continuous profile from different tools.

Automatic tool changer of machining center

A vertical-type machining center having a spindle carrier which travels in the vertical direction and a turret capable of both rotation and upward and downward movement provided on the spindle carrier, wherein tools are automatically changed over through rotation of the turret caused by relative movement between the turret and the spindle carrier when the upward movement of the turret is checked by a restraining member. A Z-axis position pulse generator is provided on a spindle mechanism drive member, such as the vertical drive motor or a screw shaft, and is adapted to generate a pulse for each revolution of the drive member. The pulses are counted by a counter which delivers a counted value for use in computing the vertical position of the spindle mechanism. The arrangement is such that the rotational speed of the vertical drive motor is controlled so as to move the spindle mechanism at an optimum speed suitable for the vertical position thereof.

Numerical control apparatus

The disclosed numerical control apparatus can process-workpiece at high speed and high precision, while suppress-ing tool abrasion, by maintaining the optimum cutting conditions determined by combination of the spindle revolution number and the tool feed speed. In the numeri-cal control apparatus (10), the spindle revolution number control sections (17, 18) changes the revolution number of the spindle according to the tool feed speed obtained by the feed speed deciding sections (11 to 15) on the basis of the tool movement form commanded by a processing program. Further, in the case of the numerical control apparatus (20), the spindle revolution number is changed by the spindle revolution number control sections (23 to 25) on the basis of the change in the contact position between the tool and the workpiece to be cut in the tool axial movement direction. Further, in the case of the numerical control apparatus (30), the spindle revolution number is changed by the spindle revolution number control sections (37 and 38) on the basis of the tool feed speed including tool axial movement direction data obtained by the feed speed deciding sections (31 to 35) on the basis of the tool movement form.

Milling method used for producing structural components

The invention relates to a milling method used for producing structural components based on materials that are difficult to machine. A milling tool (10) having a tool radius (RFW) is rotatably driven about the axis (12) of a milling tool, thereby ensuring a centered rotation of the same. According to said method, a point of reference (13) of the milling tool which preferably lies on said axis is displaced on a plurality of curved tracks (14), said tracks preferably having different curvatures. The milling tool is displaced on the tracks with a radial tool feed relative to the material. According to the invention, the curvature is determined in every location of every track in such a manner as to optimize contact of the milling tool in every point of the curvature.

Apparatus and method for working on successive segments of sheet material

Apparatus for cutting successive contiguous segments of a lay-up of sheet material 12 has a table 14, an endless conveyor 18 to position the lay-up in the cutting zone of the table, and a carriage assembly 30, 24 which moves a cutting mechanism 32, 34 relative to the table in cutting engagement with the lay-up to cut patterns in response to a programmable controller 28. An encoder 40 on the carriage assembly detects movement of the latter, relative to the conveyor, returning to its starting position after a cutting cycle, and response means 42 energises the conveyor drive motor 20 in response to the detected movement to move the lay-up in the return direction through a distance related to that traversed by the returning carriage assembly, whereby the next segment of the lay-up is accurately positioned on the table. Error sensing means 43 detects an error in positioning the lay-up and alters the data in the controller to nullify the error.

Determining cutting tool dimensions and run-out using acoustic emissions

An apparatus and method are provided for inputting parameters relating to a cutting tool and the surface of a work piece to an automated machining center, through use of acoustic emissions generated when a cutting tool is brought into contact with a work piece and/or a reference surface.

Cam machining apparatus

A cam machining apparatus are arranged such that: in a cam machining tool, oscillating motion is rendered between a work piece and a rotating tool in a manner that the center of the rotating tool stays on the normal line at a working point where the rotating tool and the work piece contact each other without making the working point shift, so that a cam can be machined with high accuracy of working without the cam contour being deformed even if the diameter of tool is changed, uniform finishing can be rendered along all the circumference of the cam face by keeping the speed of working substantially constant along all the circumference of the cam face, whereby high working accuracy can be obtained.
