Abstract

A machine tool control apparatus includes: a control program storage unit that stores control programs for performing standard running control. The control program storage unit includes a basic data memory that sets a control program for performing standard running, and a variable data memory that temporarily alters part of the control program to set a control program for performing temporary running. The machine tool control apparatus further includes a parameter check unit that checks whether a basic parameter stored in the basic data memory and a variable parameter stored in the variable data memory are “matched”; and a temporary running confirmation operation unit that enables the standard running when a parameter check result from the parameter check unit is “match” and that enables the temporary running by performing a temporary running confirmation operation while disenabling the standard running when the parameter check result is “mismatch”.

Claims

1. A machine tool control apparatus comprising:

a control program storage unit that stores therein control programs for performing standard running control in correspondence with specifications of a machine tool, the control program storage unit being provided with;

a basic data memory that sets a control program for performing standard running, and

a variable data memory that temporarily alters part of the control program to set a control program for performing temporary running;

a parameter check unit that checks whether a basic parameter stored in the basic data memory and a variable parameter stored in the variable data memory are “

matched”

with each other; and

a temporary running confirmation operation unit that enables the standard running when a parameter check result from the parameter check unit is “

match” and

that enables the temporary running by performing a temporary running confirmation operation while disenabling the standard running when the parameter check result is “

mismatch”

.

2. The machine tool control apparatus according to claim 1,

wherein the record of the “

temporary running confirmation operation”

is erased when a power supply of the machine tool is OFF; and

a fresh check between the basic parameter and the variable parameter is performed the next time the power supply is ON.

3. The machine tool control apparatus according to claim 1, further comprising:

a temporary running confirmation display unit that notifies an operator by displaying that the confirmation operation has been performed by the temporary running confirmation operation unit.

4. The machine tool control apparatus according to claim 3,

wherein the temporary running confirmation display unit includes a display having a screen on which the parameter check result is displayed.

5. The machine tool control apparatus according to claim 3,

wherein the temporary running confirmation operation unit is configured such that the operator makes a confirmation by means of an icon that is displayed on the display to confirm the variable parameter “

mismatch”

for the temporary running.
