Numeric control method and numeric control system

A numerical control method comprising:

• storing in a memory a control data of a control axis generated at every control unit time in a numerical control apparatus, the control data being obtained as an output data by performing a part program for a numerical control machine tool on an actual numerical control machine tool;
• displaying graphically the control data stored in said memory as a speed pattern on a screen, and performing a predetermined optimization process for said control data upon a processing instruction issued based on the display contents;
• storing said optimized control data in said memory;
• and
• executing the numerical control based on said optimized control data in said memory.

A numerical control system comprising:

• a memory for storing a control data of a control axis obtained by making an actual machine check for a part program of a numerical control machine tool;
• an optimization processing part for performing automatically and independently from a control by an operator an optimization process of deleting a series of control data when contents of all control items at a same time are zero for the control data stored in said memory;
• a memory for storing the control data optimized by said optimization processing part;
• and
• a numerical controlling part for executing the numerical control based on the optimized control data in said memory.

A numerical control system comprising:

• a first memory storing a control data of a control axis obtained by making an actual machine check for a part program of a numerical control machine tool;
• a second memory storing the control data stored in the first memory;
• an optimization module automatically performing an optimization process of deleting dead time of a machining apparatus, wherein the dead time is deleted by detecting when contents of all control items at a same time are zero for the control data stored in the second memory and deleting a corresponding series of control data based on the detection;
• a third memory storing the control data optimized by said optimization module;
• and
• a numerical controlling module executing the numerical control based on the optimized control data in the third memory.
