Publication number: 20080234857Abstract: A numerical controller capable of using G-code commands pursuant to ISO in a path table operation. Data of values L of a reference variable and positions of a controlled axis X on i th and (i+1) th lines are read from a path table and stored. Based on the i th and (i+1) th line data and an inputted value Lm of the reference variable, a motion path is obtained to output motion amounts of the controlled axis. Thereafter, an index i is updated, and the path table operation is performed in accordance with data in the path table and the inputted reference variable value. If a G-code is included in the read data during the path table operation, it is stored. When the reference variable value Lm reaches a reference variable value designated by a line in which the G-code is read, a command for the G-code is executed.Type: ApplicationFiled: March 17, 2008Publication date: September 25, 2008Inventors: Takahiko Endo, Tooru Watanabe

Publication number: 20080082203Abstract: A spindle is subjected to speed control and contour control according to a path table in which the speed and the position of the spindle are stored in association with a time. A switchover command for starting a contour control during speed control and a time La at which the switchover is carried out are set in advance in the path table. When the time La is reached, a spindle speed Sa and a spindle position Xa corresponding to the time La are read. Then, a time Lb and a spindle position Xb for the start of the contour control, designated next, are read. A speed is obtained from the spindle speed Sa and a speed in a first path in the contour control so that the spindle position shifts from Xa to Xb in a period between the times La and Lb. The spindle is moved from the time La to the time Lb at the obtained speed according to a designated linear function.Type: ApplicationFiled: September 5, 2007Publication date: April 3, 2008Applicant: FANUC LTDInventors: Tooru Watanabe, Yasushi Takeuchi, Takahiko Endo

Patent number: 6011942Abstract: It is desirable if the lengthwise center axis of a cylindrical rotating member such as a photoreceptor drum is aligned exactly with the center axes of the support shafts. However, as it is impossible to eliminate manufacturing errors in components, it is unavoidable for there to be a slight angle of intersection between the center axis of the cylindrical rotating member and the center axes of the support shaft. Consequently, the object of the present invention is to provide a support mechanism for the cylindrical rotating member whereby the cylindrical rotating member exhibits little unevenness of rotation. When lengthwise axis of the cylindrical rotating member forms angle of intersection .alpha. with lengthwise axis of shaft, this angle .alpha.Type: GrantFiled: May 28, 1998Date of Patent: January 4, 2000Assignee: Minolta Co., Ltd.Inventors: Hajime Taniguchi, Tooru Watanabe, Ikuro Chimoto, Akihiro Nakamura, Masato Togami
