Patent number: 8190287Abstract: Time information t and positional information about each axis are obtained, and the three-dimensional coordinates of tool center point Pe at time t are calculated to display the path of the tool center point Pe at time t. Then, whether a fixed time has elapsed or not is decided. If the fixed time has elapsed, the coordinates of the tool vector start point Ps at time t are calculated to display a line segment connecting between tool vector start point Ps and tool center point Pe, which is the end point of the tool vector. This display enables the orientation of the tool at each tool center point to be grasped at a glance.Type: GrantFiled: June 3, 2010Date of Patent: May 29, 2012Assignee: Fanuc Ltd.Inventors: Yasusuke Iwashita, Tadashi Okita, Junichi Tezuka, Kazuyuki Sugiyama

Patent number: 8010302Abstract: First and second screens are set for a tool path display apparatus for displaying a path of the tip of a tool attached to a machine tool. The first screen displays the three-dimensional path of the tip of the tool obtained by synthesizing the position information of the drive axes of a 5-axis machine tool. The second screen displays the waveforms of the position deviations and current instructions of the drive axes in chronological order. When a part (line segment) of the three-dimensional path of the tip of the tool is selected on the first screen, the display attribute of the corresponding time area is changed on the second screen so that the time area can be identified.Type: GrantFiled: June 23, 2010Date of Patent: August 30, 2011Assignee: Fanuc LtdInventors: Tadashi Okita, Hiroyuki Kawamura, Junichi Tezuka, Kazuyuki Sugiyama
