Incremential encoder (Incretely pulse coder)
The rotary position measures the element, which is installed on the engine shaft or the roller screw, and the interval pulse representation is issued during the turn. Because there is no element of memory, it is not possible to accurately represent the location of the machine tool. It is only after zero at the machine-tool and the zero point of the coordinate system of the tool-tool can indicate the location of the ouchette or the tool. It should be noted that there are two ways to take out the output from the incremental coder signal: series and parallel. The individual CNC systems correspond to serial interfaces and parallel interfaces.
Absolute Pulse Coder
Rotation of the position measurement components, the goal is the same as the incremental coder, with memory components, which can reflect the actual location of the tooltip in real time. The location of the judgment will not be lost. As an incremental encoder, pay attention to the serial output and parallel of the pulse signal during use.
Orientation (orientation)
In order to make the positioning of the pin or the change of sword, the main axis of the tool-tool must be located in the round direction of turning of the rounding of the circular circle as a reference point of the action. Generally, there are the following 4 methods: the position coder is directed, the orientation of the magnetic sensor, the signal direction at an external time (such as the switch) and the external mechanical method.
Tandem control (tandem control)
For large establishments, when an engine is not enough to drive, it can be driven by two engines. One of the two trees is the active axis and the other is the axis. The active axis receives CNC control instructions to increase the driving moment of the axis.
Rigid tap
The attack wire operation does not use the head yet floating, but the operation of synchronization of the rotation of the main axis and the attack wire in the axis. When the spindle turns, the supply volume of the attack silk shaft is equal to the screw distance of the tap, which can improve precision and efficiency. Treatment of WeChat metals, the content is good and worthy of attention. To obtain a rigid attack, the pin must be equipped with a position coder (generally 1024 pulse / each transfer) and requires the corresponding trapezoidal diagram to define the associated system parameters.
Knife compensation memory A, B, C (Tool Compensation Memory A, B, C)
The knife compensation memory can generally be defined on any type A, B or C. The external manifestation is: the quantity of geometric and wear -in -law compensation of type A does not distinguish the knife. Type B aims to separate geometric shape compensation and wear compensation. Type C not only separates geometric compensation from wear compensation, but also separates the length and radius compensation code from the tool. The length compensation code is H and the radius compensation code is D.
DNC operation (DNC operation)
It is a way to operate automatically. Use the RS-232C or RS-422 port to connect the CNC system or computer. Resolve restrictions on CNC memory capacity.
Advanced preview control (M)
This function is a pre-procedure of the interpolation of the race trajectory and the speed and acceleration of the race trajectory. This can reduce the monitoring error caused by deceleration and postal offsets. Prior reading control includes the following functions: Acceleration in a straight line before interpolation; Automatic reduction in corners speed.
Polar coordination interpolation (T)
The programming of polar coordinates consists in transforming the two right axes of the Descartes coordinate system into a horizontal axis in the form of a right axis. Usually used for a straight line location or grinding cams on the grinding bed.
Interpolation of Nurbs (M)
Most molds such as cars and planes are designed with CAD. Treatment of WeChat metals, the content is good and worthy of attention. Therefore, the CNC system has designed the corresponding interpolation function.
Automatic measurement of the length of the tool)
Installing the contact sensor on the machine and the tool measurement program (G36, G37) is prepared as the treatment program. Perform the program in automatic mode to ensure that the tool contacts the sensor, so that the difference in length between the length of it and the reference knife and automatically fill the value in the bias number specified by the program .
Contour CS (Control of the CS contour)
Control of the CS contour consists in modifying the main tree of the tour to the position control to obtain the positioning of the pin as a function of the angle of rotation, and it can be treated with other input trees to be treated to Produce complex forms.
Absolute manual value open / deactivated / deactivated
It is used to determine whether the coordinate value of manual movement is added to the current position of the automatic operation when the power supply is interrupted.
Manual interruption
Shakeing the wheel during automatic operation can increase the movement distance of the motion shaft. Used for changes in the route or size.
PMC control shaft (control of the axis by PMC)
The Servo axis controlled by PMC control (programmable machine-tool). The control instruction is compiled in the PMC (Trapezoidal diagram) program.
Control of the CF (control of the CF axis) (T series)
In the tower system, control of the rotation position (corner) of the main axis is implemented as a servomotor as an entrance to the servo. The axis is interspersed with the other in the axis and the arbitrary curve is treated. (Common in the old tower system)
Position monitoring (monitoring)
When the servo is interrupted, an emergency stop or the servo alarm is moved, if the mechanical location moves, there will be position errors in the CNC position error register. The position tracking function consists in modifying the position of monitoring the CNC controller machine tool, so that the error in the position error register becomes zero. Of course, if monitoring of the execution position must be determined according to the needs of real control.
Simple synchronous control
One of the two entries of the two in the axis is the active axis, and the other is the movement instruction of the CNC of the axis and the active tree to follow the axis of the axis of the axis To reach the synchronous movement of the two axes. CNC monitors the movement of the two axes at any time, but does not compensate for the errors of the two. at the same time. This function is often used in the double -axis driver of the large established.
Compensation for three -dimensional tools (M)
During the multi-coordinated bond treatment, the tool can be offset to compensate for the tool in the three coordinate directions during the movement of the tool movement. Compensation for treatment with the side of the knife can also be carried out and compensation for treatment with the final surface of the tool.
Tool nose radius compensation (T)
The tip of the car knife blade has arcs.
Management of the life of the tool
When you use more tools, the knife is grouped according to its life and the order of the use of the tool is defined in advance on the CNC tool management table. When the tools used during treatment can be replaced automatically or manually by the same group of knife premises when the life value is evaluated at life value. The replacement of the knife must be compiled by a trapezoidal table.
