Abstract
Abstract An interface unit simplifies the definition or correction of the contents of conversion from a macro instruction into micro instructions by the machine tool maker, without changing the specifications of the NC processor (3) side in numerical control equipment (NC). A receiving circuit (9, 10) receives a macro instruction delivered from the NC processor (3), and format converting circuitry (6, 8) converts the macro instruction received by the receiving circuit (9, 10) into a series of micro instructions. A transmitting circuit (11, 12) transmits the series of micro instructions obtained by the format converting circuitry (6, 8) to the NC processor (3).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
A format conversion interface unit adapted for connection to numerical control equipment which numerically controls a machine tool by interpreting and executing an NC cutting program through use of an operation function of an NC processor, comprising: a receiving circuit, coupled to the NC processor, for receiving a macro instruction delivered from the NC processor; format converting means, separate from the NC processor, for converting the macro instruction received by said receiving circuit into a series of micro instructions in accordance with a conversion program stored in said format converting means, so that the NC cutting program can be used to cause said format converting means to generate different micro instructions by rewriting only the conversion program stored in said format converting means; and a transmitting circuit, coupled to the NC processor and said format converting means, for transmitting the series of micro instructions obtained by said format converting means to the NC processor.
Claim 2
Dependent Claim
154 words
A format conversion interface unit adapted for connection to numerical control equipment which numerically controls a machine tool by interpreting and executing an NC cutting program through use of an operation function of an NC processor, comprising: a receiving circuit, coupled to the NC processor, for receiving a macro instruction delivered from the NC processor; format converting means, separate from the NC processor, for converting the macro instruction received by said receiving circuit into a series of micro instructions in accordance with a conversion program stored in said format converting means, so that the NC cutting program can be used to cause said format converting means to generate different micro instructions by rewriting only the conversion program stored in said format converting means; and a transmitting circuit, coupled to the NC processor and said format converting means, for transmitting the series of micro instructions obtained by said format converting means to the NC processor.
Claim 3
Dependent Claim
130 words
A format conversion interface unit adapted for connection to numerical control equipment including an NC processor for controlling a machine tool under control of an NC program including macro instructions and NC program micro instructions, comprising: receiving means for receiving a macro instruction from the NC processor; format converting means, separate from the NC processor, for converting the macro instruction received by said receiving means into a series of converted micro instructions in accordance with a conversion program stored in said format converting means, so that the NC program can be used to cause said format converting means to generate different micro instructions by rewriting only the conversion program stored in said format converting means; and transmitting means for transmitting the series of converted micro instructions to the NC processor.
Claim 4
Dependent Claim
130 words
A format conversion interface unit adapted for connection to numerical control equipment including an NC processor for controlling a machine tool under control of an NC program including macro instructions and NC program micro instructions, comprising: receiving means for receiving a macro instruction from the NC processor; format converting means, separate from the NC processor, for converting the macro instruction received by said receiving means into a series of converted micro instructions in accordance with a conversion program stored in said format converting means, so that the NC program can be used to cause said format converting means to generate different micro instructions by rewriting only the conversion program stored in said format converting means; and transmitting means for transmitting the series of converted micro instructions to the NC processor.
Claim 5
Dependent Claim
88 words
A format conversion interface unit as set forth in claim 2, wherein said format converting means comprises: a memory, coupled to said transmitting means, for storing the conversion program which includes a correspondence between the macro instructions in the NC program and the converted micro instructions; and a format conversion processor, coupled to said memory and said receiving means, for receiving the macro instruction from said receiving means and for causing a corresponding series of converted micro instructions to be read from said memory to said transmitting means.
Claim 6
Dependent Claim
45 words
A format conversion interface unit as set forth in claim 3, wherein: said receiving means comprises an input register coupled to the NC processor and said format conversion processor; and said transmitting means comprises an output register coupled to said memory and the NC processor.
Claim 7
Dependent Claim
97 words
A format conversion interface unit as set forth in claim 4, further comprising: an input flag, coupled to the NC processor and said format conversion processor, for indicating when the NC processor has provided a macro instruction to said input register; an output flag, coupled to the NC processor and said format conversion processor, for indicating when a series of converted micro instructions have been stored in said output register; and an in-cycle flag, coupled to the NC processor and said format conversion processor, for indicating when said format conversion processor is performing a format conversion process.
Claim 8
Dependent Claim
19 words
A format conversion interface unit as set forth in claim 5, wherein said memory comprises a magnetic bubble memory.
