Title: Setting method for height of working start surface
Inventor: SEKI MAKI
IPC: G05B19/4093
Filed: 1988-07-15
Abstract: PURPOSE:To easily designate the height of a working start surface by defining the bottom surface of a pocket or the top of an island of a 1st form as the working start height of a 2nd form in case the master-slave relation is designated between the pocket-shaped or island-shaped 1st form and the 2nd form. CONSTITUTION:When the master-slave relation is designated between a pocket- shaped 1st form 1 and a 2nd form 2, the height of the pocket surface of the 1st form 1 is defined as the working start surface PSH of the 2nd form 2. If the form 1 has an island shape, the height of the island top is defined as the height of the PSH of the form 2. Therefore it is not required each time to check the height of the pocket bottom surface or the island top nor to perform the key input operation in the numerical value. Furthermore the independent correction is not needed for the height of the PSH of the form 2 in case the island top or the pocket bottom of the form 1 is corrected. Thus the height of the PSH can be easily designated.
