Claims
- 1. A manual numerical control unit operatively connected to an industrial machine and operatively connectable to an external unit for storing a machining program, comprising:
- a program creating device including:
- input means for entering data for the creation of a machining program;
- a first processor, operatively connected to said input means, for creating a machining program in accordance with the entered data; and
- a first memory, operatively connected to said first processor, for storing the created machining program;
- a machine control device including:
- a second memory, operatively connectable to said first memory, for storing a machining program transferred from said first memory; and
- a second processor, operatively connected to said second memory, for executing the machining program stored in said second memory to numerically control the industrial machine; and
- a switching circuit, operatively connected to said program creating device and said machine control device, and having a connector for coupling to the external unit, for selectively coupling the external unit to said program creating device or to said machine control device, and for selectively connecting said first and second memories to transfer the machining program from said program creating device to said machine control device, said switching circuit being disconnected when said program creating device is to perform machining program creation concurrently with said machine control device numerically controlling the industrial machine.
- 2. A manual numerical control unit according to claim 1, wherein said switching circuit is adapted to selectively interconnect said program creating device and said machine control device.
- 3. A manual numerical control unit according to claim 2, wherein the external unit is a storage unit, and wherein data is sent and received between the external unit and said first memory of said program creating device or said second memory of said machine control device in dependence upon the state of said switching circuit.
- 4. A manual numerical control unit according to claim 1, wherein the external unit is a storage unit, and wherein data is sent and received between the external unit and said first memory of said program creating device or said second memory of said machine control device in dependence upon the state of said switching circuit.
- 5. A manual numerical control unit according to claim 2, wherein the external unit is a storage unit, and wherein data is sent and received between the external unit and said first memory of said program creating device or said second memory of said machine control device in dependence upon the state of said switching circuit.
- 6. A manual numerical control unit operatively connectable to an industrial machine and an external unit for storing a machining program, comprising:
- a machine program creating device for creating a machining program, including:
- first means for entering data for the creation of the machining program;
- second means, operatively connected to said first means, for creating the machining program in accordance with the entered data; and
- third means, operatively connected to said second means, for storing the created machining program;
- a machine control device including:
- fourth means for storing a completed machining program; and
- fifth means, operatively connected to said fourth means, for executing the completed machining program stored in said fourth means to numerically control the industrial machine; and
- a switching circuit, operatively connected to said third means and said fourth means, and having a connector for coupling to the external unit, for selectively connecting said third means, said fourth means and the external unit, said switching circuit having a first state in which said third means is operatively connected to said fourth means to transfer the created machining program from said third means to said fourth means for storage as the completed machining program, said switching circuit having a second state in which the external unit is operatively connected to said third means, said switching circuit having a third state in which the external unit is operatively connected to said fourth means, said switching circuit having a fourth state in which the third and fourth means are disconnected from each other and disconnected from the external unit, so that when said switching circuit is in the fourth state said program creating device performs machining program creation concurrently with said machine control device numerically controlling the industrial machine.
- 7. A numerical control unit according to claim 6, wherein the external unit is a storage unit, wherein the storage unit is capable of storing the created machine programs stored in said third means when said switching circuit is in the second state, and wherein the storage unit is capable of transmitting data to said fourth means or receiving the completed machining program from said fourth means when said switching circuit is in the third state.
