Abstract
Abstract An apparatus for controlling a machine tool including a tool holder spindle for performing a machining operation, a motor for rotating the spindle, an operator's control panel which has a data display with a plurality of display digits, and a plurality of operator's control switches, and a control device comprising a motor controller for controlling the spindle motor, according to control data entered through the operator's control switches. The control device includes a special-operation detector for detecting one of at least one special operation of at least one of the control switches, a mode selector for selecting one of at least one special operation mode of the control device corresponding to the detected one of the at least one special operation, and a special data setting controller for placing the data display in the selected one special operation mode and permitting the control device to enter special presetting data through the control switches.

Claim 2
Independent Claim
198 words
An apparatus for controlling a machine tool including holding means for holding a member for performing a machining operation, driving means for driving said member, an operator's control panel which has a data display with a plurality of display digits, and a plurality of operator's control switches, and a control device comprising a controller for controlling said driving means, according to control data entered through said operator's control switches, wherein said control device comprises: special-operation detecting means for detecting one of at least one special operation of at least one of said plurality of operator's control switches; mode selecting means responsive to said special-operation detecting means, for selecting one of at least one special operation mode of said control device which corresponds to the detected one of said at least one special operation; and special data setting control means responsive to said mode selecting means, for placing said data display in the selected one special operation mode and permitting said control device to enter special presetting data through said operator's control switches, said special presetting data being associated with said machining operation, said control device being operable to control said driving means according to said special presetting data.
Claim 3
Dependent Claim
35 words
An apparatus according to claim 1, wherein said special-operation detecting means detects one of said at least one special operation by detecting concurrent operations of a plurality of control switches of said operator's control switches.
Claim 4
Dependent Claim
43 words
An apparatus according to claim 1, wherein said special-operation detecting means detects one of said at least one special operation by detecting concurrent operations of a plurality of control switches of said operator's control switches, for at least a predetermined length of time.
Claim 5
Dependent Claim
17 words
An apparatus according to claim 3, wherein said predetermined length of time is at least three seconds.
Claim 6
Dependent Claim
39 words
An apparatus according to claim 1, wherein said special-operation detecting means detects one of said at least one special operation by detecting an operation of one of said operator's control switches for at least a predetermined length of time.
Claim 7
Dependent Claim
75 words
An apparatus according to claim 1, wherein said operator's control panel has a plurality of mode selector switches for establishing respective normal operation modes of said control device different from said at least one special operation mode, said mode selecting means changing one of said normal operation modes to said selected one special operation mode when said special-operation detecting means detects said one special operation of said at least one of said operator's control switches.
Claim 8
Dependent Claim
35 words
An apparatus according to claim 6, wherein said operator's control panel further has a plurality of data setting switches for entering said special presetting data under the control of said special data setting control means.
