Abstract

PURPOSE:To reduce vibration and noise and improve surface roughness and permit double grinding by comparing the present feed-speed signal in the form of pulse signals and a predetermined feed signal and controlling a driving source according to the result of said comparison and increasing and decreasing the transfer speed within a proper range. CONSTITUTION:A table 5 starts shift at a feed speed previously selected and the pulse signals supplied from a transfer pulse detector 9 are transmitted into a present feed-speed detection part 10, and the pulse signals per proper transfer amount or per transfer time of the table 5 are counted, and the feed speed of the table 5 at present is detected in correspondence with the pulse signals supplied from a time pulse generator 11. Said speed is compared with the predetermined transfer mode in a calculation part 14, and a deviation signal is fed into a correction part 15, and a correction signal is fed into a control part 16, and then the control signal for the motor 8 is corrected, and therefore, the motor 8 is controlled so as to shift in a predetermined transfer mode previously set at the selected feed-speed for the table 5. Therefore, vibration and noise can be reduced by putting the table 5 into inequal movement.

In view of the above-mentioned current state of grinding processing, the present invention aims to reduce vibration and noise and improve surface roughness by variably controlling the cutting motion or feeding motion itself during grinding processing, and also aims to reduce vibration and noise and improve surface roughness. This method was developed with the aim of providing a control method and device that would enable heavy cutting, which was previously impossible. The method is characterized in that the selected grinding feed rate is increased or decreased within an appropriate range, and the configuration of the apparatus for carrying out this method is such that the grinding feed rate in the grinding machine is changed by increasing or decreasing the selected grinding feed rate within an appropriate range. The movement pulse signal supplied from the movement pulse detector provided on the member that performs the feeding movement is made to correspond to an appropriate time pulse, and the current feed speed signal is expressed as a movement amount/time or a pulse signal expressed as time/movement amount. On the other hand, the driving source for moving the member that performs the feeding movement is
The feed movement is driven by an arbitrarily set movement amount/time including an increase/decrease in speed at the selected feed speed of the member performing the grinding feed movement, or a scheduled feed speed signal based on a pulse signal representing the time/movement amount. When moving the member that performs the grinding and feeding motion, the current moving speed signal and the scheduled moving speed signal are compared and calculated, and the driving source is controlled based on the result of this calculation, thereby increasing or decreasing the moving speed of the member that performs the grinding feed movement within an appropriate range.

In this way, the table 5 initially starts to move at a preselected feed rate, but at the same time as the table 5 starts moving, a pulse signal supplied from the movement pulse detector 9 is sent to the current feed rate detection section 10. Here, the pulse signal per unit movement amount or unit movement time of the table 5 is counted, and the current feed speed of the table 5 is detected in correspondence with the pulse signal from the clock pulse generator 11. Ru. This current feed speed is compared and calculated with the scheduled movement mode in the calculation section 14, and a deviation signal based on the calculation result is supplied to the correction section 15. Since the correction section 15 supplies the correction signal formed therein to the control section 16, the control section 1
6, the control signal for the motor 8 is corrected, so that the rotation of the motor 8 is controlled so that the motor 8 moves in a preset scheduled movement mode at the feed rate selected for the table 5.

When the rotation of the motor 8 is controlled at the selected feed rate of the table 5 and the grinding feed of the table 5 is caused to move at an inconstant velocity, the relative speed of the grindstone to the rigid material is finely increased or decreased during grinding. This makes it possible to perform grinding without causing vibration during grinding, which is likely to occur due to single mode rotation of the grindstone and feeding of the table in jet mode.

In the present invention, in general, the feeding of the table 5 is selected in advance according to the material of the stiffened material, etc., so that the feeding of the table 5 at non-uniform speed does not have an adverse effect on the roughness of one surface. Although it is given in the range of about ±10 to 15% of the speed, the above range may be made larger than the range of the embodiment, or conversely may be made smaller depending on the cutting conditions such as the material of the workpiece.
