Abstract
Abstract A programming arrangement for machine tools wherein address characters are presented sequentially and call sequentially for the insertion of data, the data being registered on a block-byblock basis and transferred so as registered into a machine control logic unit; and a machine control logic unit providing automatic direction sensing, speed control, backlash and tool compensation and accurate motor drive control.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
114 words
A numerical control system for programming a machine which utilizes several instructions simultaneously, said system comprising a machine data storage unit capable of storing at the same time several groups of signals, each group representing one of said several instructions, when said groups are presented to said storage unit in a given sequence, signal generator means capable of producing individual signals corresponding to individual commands making up said instructions, means for entering the output of said signal generator means into said machine data storage unit and means responsive to the entry of each group of signals from said generator means into said storage unit to identify the following signal group in said given sequence.
Claim 2
Dependent Claim
114 words
A numerical control system for programming a machine which utilizes several instructions simultaneously, said system comprising a machine data storage unit capable of storing at the same time several groups of signals, each group representing one of said several instructions, when said groups are presented to said storage unit in a given sequence, signal generator means capable of producing individual signals corresponding to individual commands making up said instructions, means for entering the output of said signal generator means into said machine data storage unit and means responsive to the entry of each group of signals from said generator means into said storage unit to identify the following signal group in said given sequence.
Claim 3
Dependent Claim
31 words
A numerical control system according to claim 1 and further including means for indicating the commands selected for each instruction in advance of operation of said means for entering the output.
Claim 4
Dependent Claim
32 words
A numerical control system according to claim 1 and further including means for clearing undesired command signals from said signal generator means prior to operation of said means for entering the output.
Claim 5
Dependent Claim
29 words
A numerical control system according to claim 1 wherein said signal generator means includes means for serially generating signals corresponding to each command on a digit by digit basis.
Claim 6
Dependent Claim
31 words
A numerical control system according to claim 1 further including means operative to inhibit operation of said means for entering the output prior to generation of signals for a complete instruction.
Claim 7
Dependent Claim
36 words
A control system according to claim 1 wherein said signal generator means includes a register for accumulating each of the signals in one group and means for entering the signals into the register in serial manner.
Claim 8
Dependent Claim
41 words
A control system according to claim 6 wherein said means directing the output of said signal generator means comprises scanner means operative to scan and register and transmit the scanned signal information in said register to said machine data storage unit.
Claim 9
Dependent Claim
73 words
A control system according to claim 7 wherein said means responsive to the entry of each group of signals comprises an address sequencing counter responsive to successive input signals to produce different signals representative of a new address, indicator means responsive to said different signals to produce corresponding different address indications and means supplying input signals to said address sequencing counter in response to the completion of each operation of said scanner means.
Claim 10
Dependent Claim
24 words
A control system according to claim 1 wherein said system includes a record making means operative to record the signals from said signal generator.
Claim 11
Dependent Claim
59 words
A control system according to claim 9 wherein said record making means is operative to record said signals across a segment of a recording medium and wherein said record making means is operative to advance said medium to a new segment in response to the entry of each group of signals from said generator means into said storage unit.
Claim 12
Dependent Claim
28 words
A numerical control system according to claim 1 further including a machine control logic unit connected to receive said several groups of signals simultaneously from said storage unit.
Claim 13
Dependent Claim
28 words
A numerical control system according to claim 11 wherein said machine control logic unit is operative to inhibit transfer of signals from said storage unit during machine operation.
Claim 14
Dependent Claim
23 words
A numerical control system according to claim 12 wherein said storage unit is operative to receive further groups of signals during machine operation.
