Abstract

PURPOSE: To improve accuracy in form and roughness of a finished plane in a milling work by enabling to cut under a constant amount of feeding and at a constant cutting speed.
CONSTITUTION: A work 3 fixed to a chuck 2 is rotated by a variable speed motor 4 for a revolving shaft 1 and is cut by a cutter 6 fixed to a table 7. The table 7 is fed by a variable speed motor 9 through a screw 8. A rack 10 attached to the table 7 is engaged with a pinion 11 and an encoder 12 for cutter location is connected to the pinnon 11. Signals from the encoder 12 are sent to a controller 13 for the revolving shaft 1 and a controller 14 for the table 7, and electric currents are supplied to motors 4, 9 respectively, and thereby, cutting at a constant cutting speed and under a constant amount of feeding may be effected against the work 3.
