摘要： A numerical controller calculates a first position command from a machining program, converts the first position command into a second position command for restricting a tangential speed of a tool, and delivers the second position command and a status signal indicative of the achievement of the conversion of the first position command into the second position command to a tool path display apparatus. The tool path display apparatus displays the path of the tool in a color corresponding to the status signal and can thereby determine the point on the tool path at which the speed restriction is performed.

摘要： A control device, for a servo die cushion, by which the speed of a die cushion is prevented from largely deviating from the speed of a slide, whereby the press force between the slide and the die cushion is not significantly reduced. The control device includes a slide speed detector for detecting the speed of the slide, a die cushion speed detector for detecting the speed of the die cushion, and a die cushion speed commanding part for controlling the speed of the die cushion. When a tentative speed command of the die cushion is largely deviated from the detected slide speed, the command of the die cushion is corrected such that the absolute value thereof does not exceed the value calculated by adding the absolute value of the detected slide speed to a positive constant.

摘要： A controller for a servomotor capable of improving accuracy of positioning and quality of a machined surface by switching modes of correction of a position command or the like, and reducing a shock at the time of switching. A correction amount generating section obtains a correction amount based on a value of a correction factor such as machine temperature. When the external signal is in ON state, a position command or the like is corrected by the correction amount obtained by the correction amount generating section and sent via switches. A correction amount holding section holds the correction amount obtained by the correction amount generating section. When the external signal turns to OFF state, the connection of the switches is changed so that correction is performed by the correction amount held in the correction amount holding section. When the connection of the switches is changed, the correction amount does not change rapidly, so that the machine does not suffer a shock. In positioning, the external signal is turns to ON state, so that the positioning is carried out accurately by performing correction by the correction amount sent from the correction amount generating section. When a high-quality machined surface is required, the external signal is turned to OFF state so that the correction amount does not change to achieve improvement in the quality of a machined surface.
