Numerically-controlled machine tool processing platform side, detection direction is parallel to numerically-controlled machine tool processing platform plane, and adds perpendicular to numerically-controlled machine tool
Work line；Second laser distance measuring sensor is longitudinally disposed at numerically-controlled machine tool processing platform side, and detection direction is perpendicular to numerical control machine
Bed processing platform plane；Third laser range sensor is angularly disposed in numerically-controlled machine tool processing platform side, detection direction with
Numerically-controlled machine tool processing platform plane is at an acute angle, and perpendicular to numerically-controlled machine tool processing line.
This active fail-safe system is realized by following steps:
S1. first processor pre-sets: connecting system power supply, is sent out by first processor three laser range sensors
The dead-center position for the laser beam penetrated is configured, and the margin of tolerance of laser beam dead-center position is arranged；
S2. laser detector pre-sets: the laser beam that three laser range sensors emit is adjusted to have set
Laser beam dead-center position, and the laser beam dead-center position is brought into machine tool mechanical coordinate system, enable it fill as laser detection
Zero setting point；
S3. digital control system detection program pre-sets: cutter intelligence mutually inspection numerical control journey is added before tool sharpening numerical control program
Tool-information write-in intelligence is mutually examined in numerical control program, and enables it as cutter into numerical control variable tool-information assignment by sequence
Variable；
S4. the realization process of cutter active mistake proofing, including following sub-step:
S41. operator installs cutter according to the tool-information in intelligence mutually inspection numerical control program, is arranged on part to be processed
Good workpiece numerical-controlled program zero point, operation processing numerical control program are processed in numerical control program and call intelligence mutually inspection numerical control program, intelligence automatically
Numerical control program can mutually be examined, and will actively to read the dead-center position under current part workpiece coordinate system each under machine tool mechanical coordinate system
Axial coordinate value, and the value read is imparted in variable, enable it as zero point coordinate variable；
S42. mutually inspection numerical control program passes through formula to intelligence: laser detector zero point-zero point coordinate variable-cutter variable=
Zero, it is calculated, using its calculated result as the mobile numerical value of each axis, mutually inspection numerical control program executes the mobile number after calculating to intelligence
Value, is moved respectively to cutter on laser detector, and make three measurement points of laser detector all in laser respectively
In detection device zero point；
S43. three laser range sensors measure cutter, and by measurement feedback to first processor, and
One processor is compared measurement result with the tool-information having been written into one by one, if greatest measure be arranged in laser beam zero
In the point margin of tolerance, first processor exports normal signal at this time, and is shown on display；If greatest measure is not in laser
When in the zero point margin of tolerance of beam setting, step S44 is executed；
S44. cutter active mistake proofing: first processor will export 5V voltage to second processor, and second processor passes through change
5V voltage is converted to 12V voltage and feeds back to warning circuit by depressor, and lathe is made to be in alarm condition, blocks intelligence mutually inspection number
Control program continues to run, and stops lathe normal work, while comparison result being shown on display.
It in the embodiments of the present invention, may be implemented through the above steps: as long as laser distance detector detects
Practical tool-information be not inconsistent with the tool-information in numerical control program, lathe is in alarm condition always, and program can not be after reforwarding
Row, until it is correct using cutter, it just can guarantee that program smoothly executes.
