摘要： PURPOSE:To improve return accuracy and shorten the return period of time in a system for returning a spindle to the origin in a numerically controlled machine tool, by providing a suborigin and a near point with respect to the main origin so as to return the spindle to the near point at a high speed, to the suborigin at a medium speed, and to the main origin at the lowest speed. CONSTITUTION:In return operation of a spindle to the origin, an X-axis table 10 is moved at a high speed until a near point signal is detected, and the near point signal K is latched by a latch circuit 64, and thereafter a latched output K0 is inputted to an NC device 32 to be converted to a medium speed command. Then, the initial origin signal G outputted from a rotational angle detector 62 with the origin signal is latched by a latch circuit 66 and a latched signal G1 is inputted to the NC device 32, wherein this initial origin is set as a suborigin. At this time, the table 10 is moved at the lowest speed until the difference E computed by an error counter 58 becomes zero. With this constitution, return accuracy may be improved and the return period of time may be shortened.

摘要： PURPOSE:To perform the shift control of an industrial robot with no temporary stop nor the collision against an obstacle, by securing a curve shift where a shift route decided from the synthesization of speed components of an optimum speed pattern has the smooth variation of speed according to the result of synthesization of the orthogonal components of a mobile plane. CONSTITUTION:For instance, mobile spots P0-P3 are supplied in the form of data. Then each distance among these spots is calculated, and the speed components are synthesized in terms of a mobile plane for independent coordinate axis directions, i.e., horizontal two axes and a vertical optimum speed pattern. Then shift speeds are calculated on a mobile route and at a prescribed spot on the mobile route. Based on these data, the shift of a robot is controlled. For the optimum speed pattern, an acceleration section (a) is equal to a curve part formed by synthesizing a sign curve immediately before the rise of the speed is linear and enters a fixed speed section (b) with these sections (a) and (b) and a deceleration section (c) in the axial direction and in a linear section between the spots P0 and P1. Then a curve is obtained with synthesization of the sign curve in the section (c) following the section (b). Thus a smooth end is secured with the robot shift.

摘要： PURPOSE:To detect and set easily and assuredly a low-speed area by detecting automatically an optimum low-speed area which has a low-speed shift between a position near the target position and the target position and setting automatically the detected area. CONSTITUTION:A high-speed shift is carried out between the present position and the target position, and low-speed shift is carried out between a position near the target position and the target position. A specific relation is secured between the length of a low-speed area and the cycle time by a machine device that performed the above-mentioned positioning control. Thus said specific relation is detected and an optimum low-speed area is set to the machine device. For this detection/setting action, an automatic operation is carried out just in a single cycle in the smallest state of the low-speed area. Then the low-speed area is increased successively and at the same time the automatic operation is performed every cycle. At the same time, each cycle time is measured and these cycle times are compared with each other for detection of a point where the cycle time of this time is larger than the preceding one. Then the area set at this time point is set as the optimum low-speed area.

摘要： PURPOSE:To improve measuring efficiency, by moving a probe in the direction of a part where the probe and the object to be measured are contacted at a high speed relatively, thereafter relatively moving the probe at a low speed before the part where the probe and the measuring reference point of the object to be measured are contacted, further relatively moving the probe at the low moving speed from the measuring reference point by a specified distance, thereafter moving the probe relatively at an accelerating speed, thereby keeping the measuring accuracy highly accurate. CONSTITUTION:A probe is moved from the surface to be measured W1 to the surface to be measured W2 of the object to be measured W. At this time, the probe is acceleratingly moved from the position P1, which is contacted with the surface to be measured W1 to the position P2, in the direction separating from the surface to be measured W1. The probe is moved from the position P2 to the position P3 at the high speed. Then the probe is moved from the position P3 at a decelerating speed, and stopped at the position P4. Then the probe is moved from the position P4 to be position P5 at the accelerating speed in the direction perpendicular to the previous moving direction. Then the probe is moved from the position P5 to the position P6 at a high speed. Thereafter the probe is moved from the position P6 at the decelerating speed and stopped at the position P7 facing the surface to be measured W2. Then the probe is acceleratingly moved from the position P7 to the position P8 in the direction contacting the surface to be measured W2.

摘要： PURPOSE:To prevent a tool from being beforehand by starting adjustment control in correspondence with the output signal supplied from a contact detecting circuit for detecting the contact of a tool with a workpiece and reducing the feeding speed at this time in comparison with the speed before the contact of the tool. CONSTITUTION:When a tool T contacts with a workpiece W, a contact detection signal TDS is outputted from a contact detecting means A, and an adjustment control starting means C operates an adjustment control means B. At the same time, a speed reducing means D reduces the feeding speed of the tool T at the start of adjustment control to a prescribed speed. Therefore, the tool T is not applied with the load over an allowable value when the tool T contacts with the workpiece W, and the optimum feeding control is carried-out, starting the adjustment control immediately after contact. Therefore, the tool is prevented from being damaged because of the application of a large load onto the cutting edge part of the tool.

摘要： PURPOSE:To improve machining efficiency, by a method wherein machining speed changeover position data among numerical control data are made into reference data for changeover of a machining speed by applying the data according to their machining part and machining substance. CONSTITUTION:Data giving a changeover position of a machining feed speed of a grinding wheel 42 stored for a purpose of maintenance in a main memory 12 of a numerical controller 10 are applied to a control part 20 of a fixed length according to respective machining parts, for example, machining parts of a work in a multistate diametral shape. Feedback of a decision signal to the numerical controller 10 is performed by comparing reference voltage generated by the control part 20 of the fixed length according to its data with a measured signal of the external diameter of the work 60 by an external diameter sensor 30. A machining speed of the grinding wheel 42 is changed over optionally based on the decision signal. Machining efficiency, therefore, is improved and a numerical control program is not complicated even if sending out timing of the decision signal is varied at every machining part.

摘要： PURPOSE:To precisely detect fluctuation in true turning torque of a drill caused by cutting torque in such a way that turning torque of the drill can be detected by means of measuring relative angular displacement between a prime mover shaft and a driven shaft with use of a counter. CONSTITUTION:Relative angular displacement between a prime mover shaft 13 and a driven shaft 15 is numerated using a counter 192, it detects turning torque of a drill, and after initiating the operation, the number of its pulse string is memorized in a circuit 216 while the drill is not cutting. In comparison of the value B1 in which the determined setpoint (A) is added to the content in this circuit 216 with the content in this counter which are taken into a circuit 226, upon its coincidence, signal SG20 is given as output. At the same time as a reciprocating driving means is controlled in the control circuit so that a main shaft is once returned and moved forward again, while the main shaft is in no operation of cutting in the process of reciprocation, the content in the counter 192 is newly memorized in the memory circuit 216 by means of the control circuit.

摘要： PURPOSE:To judge the positions of a tool and a work, to move the tool at a high speed when the tool is outside the work, and to shorten an idle movement time by inputting the contour shape of the work previously before working for facing work such as milling work, and comparing this shape data with work routes. CONSTITUTION:When the facing work of the work 10 such as milling work is carried out, the contour shape 100 of the work 10 before working is inputted previously. This data on the contour shape 100 is compared with the work routes l1-l7 to judge whether the tool is outide the contour shape 100 of the work or not. When this judgement is made, the respective work routes l1-l7 are represented by a work route l to decide on intersections P1-P4 of the work route l and the contour shape of the work 10, and idle work areas are determined as areas between a work start point P0 and the 1st intersection P1, between the intersections P2 and P3, and between the intersection P4 and a final work point P0. Further, actual work areas are determined between the intersections P1 and P2, and between P3 and P4. Then, tool is moved at the high speed in the idle work areas to shorten the idle movement time of the tool.

摘要： PURPOSE:To judge the position of a tool, to move the tool at a high speed when the tool is outside the shape of a work before machining, and to shorten the idle movement time of the tool by inputting the shape of the work previously before machinging when NC work employing profile work is performed, and comparing this shape data with work routes. CONSTITUTION:The shape of the work 12 before machining is inputted in order to its final work shape 20. This previously-inputted shape of the work 12 is compared with the work routes l1-l4 set for obtaining the final work shape 20 to judge whether the working tool is outside of the work shape or not. When the work is carried out along the work route l1, intersections P1-P4 of the shape of the work 12 and work route l1 are found and it is judged that the tool is outside the work 12 from a work start point Q1 to the intersection P1 and from the intersection P2 to the intersection P3. An area shown by a dotted line is regards as an idle movement area by the judgement to move the tool at the high speed, and the tool is moved slowly in an actual work area shown by a solid line. Then, the same work method is employed for the work routes l2-l4.
