    摘要: The invention relates to a numeric control engraving machine which can be used to engrave different objects such as gems, plates of metal or another material, such as to produce the effect obtained by means of artisan engraving with a chisel, in which the tradesperson performs a downward/upward movement with the chisel with each insertion made in the surface of the body to be engraved, such that the engraved line has a curvilinear trajectory. In addition to the three axes (X, Y, Z) or degrees of freedom for the movement of the tool holder, the inventive engraving machine also creates two complementary axes which are denoted as PT (depth of line) and SV (vector tracing), thereby producing the same type of engraving as that obtained by a tradesperson with a chisel. The PT axis controls the penetration movement of the tool for the curvilinear line over the course of the vector that defines the direction and sense of the line. The SV (vector tracing) axis orients the cutting edge of the tool with the correct engraving angle.

    摘要: Peck drilling operations using a drilling tool with a rotatable bit are controlled according to the present invention. A control computer is used to detect various drilling conditions, such as dull or broken bits, transitions between different materials in a workpiece and a breakthrough condition. The control computer continually monitors the thrust and torque applied to the drill bit. A separate feed amp and computer having a pre-programmed feed motion routine for controlling the feeding movement of the drill bit signals the control computer when the bit is in a peck cycle. The control computer is responsive to an indication that the bit is a peck cycle for ignoring the thrust and torque readings during the peck cycle. By determining when the bit is in a peck cycle, the control computer is able to differentiate between a normal peck cycle and other drilling conditions, such as a dull or broken drill bit, transition between materials or breakthrough.

    摘要: Assuming that t1 represents a period of time until a detection signal is outputted after a sensor senses a laser beam passed through a through-hole of a workpiece, t2 represents a period of time until the detection signal derived from the sensor exceeds a preset threshold value, and t3 represents a period of time until radiation of the laser beam is actually stopped after the threshold value is exceeded, a total period of time (t1nullt2nullt3) of the periods of time t1 to t3 is set to be shorter than a time difference (T2nullT3) between a pulse width (T3) and one cycle (T2) of a pulse signal for constructing a laser output command signal.

    摘要: The invention relates to a method for checking performance of the cutting-off operation on automatic lathes for working bar material or the like. In accordance with the invention, operating conditions are initiated at the end of a prescribed time interval for the cutting-off operation which result in relative rotation of the spindles in opposite directions in the event that the material has been completely severed at the cutting-off point. A discrepancy between the specified and the actual relative rotation is interpreted as a system failure due to the presence of a material link at the cutting-off point, whereupon a corresponding error signal is triggered.

    摘要: When the amount of a change in load current supplied to a grinder is not more than a predetermined threshold value, the amount of piercing into a workpiece by the grinder is controlled according to the load current. When the amount of a change in load current exceeds the predetermined threshold value, the grinding speed of the grinder is controlled according to the load current. When performing a plurality of operations with one robot, a position correction value calculated in one operation is utilized to correct a target position in another operation.

A decrease in pressure caused within the shield by a pierce-through condition created by the piercing force is then detected. A method and apparatus for detecting the distance between a nozzle assembly for a machining process and a workpiece to be machined in which gas is supplied to a shield surrounding a nozzle assembly. An increase in pressure in the shield is detected as an open end of the shield approaches a workpiece to be machined. A method and apparatus for obtaining and maintaining a predetermined gap distance between nozzle assembly and a workpiece for a machining process are provided by further detecting when the pressure within the shield means reaches a pressure corresponding values and ranges. A method and apparatus for determining the thickness of a workpiece is further provided by comparing an established nozzle assembly position with a predetermined reference position.
