When programming a large-scale computer gong, the selection of tool setting point should be considered first. The determination of tool setting point and tool change point is the starting point of tool movement relative to workpiece in the process of numerical control machining. Since the program is also executed from this point, the tool setting point is also called the program starting point or starting point. When the machining accuracy requirements are not high, some surfaces on the workpiece or fixture can be directly used as the tool alignment surface; when the machining accuracy requirements are high, the tool alignment point should be selected on the design basis or process basis of the part as much as possible, for example, for the parts with hole positioning, the axis of the hole taken as the tool alignment point is more appropriate. The tool setting point must have a certain coordinate relationship with the positioning datum of the workpiece. In this way, the relationship between the coordinate system of the machine tool and the workpiece can be determined. The selection of tool setting point in computer gong processing should be convenient for the calculation of coordinate value and the tool setting. During the tool setting, the tool setting point shall coincide with the tool position. The so-called tool point refers to the intersection of the tool axis and the tool bottom surface for the flat end milling cutter; the ball end milling cutter refers to the ball center of the ball head part; the turning tool refers to the tool tip; the drill bit refers to the drill tip; for the machining of Dongguan Mechanical parts, for the WEDM machine, it refers to the focus of the WEDM axis and the part surface. (1) Stress and warpage analysis based on double side flow technology
According to the analysis results of gate solidification effect and pressure and temperature distribution, the stress and warpage analysis module calculates the change of stress with time in the wall thickness and plane direction of the product and the shrinkage of the product in the wall thickness direction at the time of demoulding. A special double-layer shell element is used to predict the warpage of the product at the time of demoulding.
(2) The combination of numerical calculation and artificial intelligence technology
Traditional CAE software is basically a passive computing tool. Before analysis, users need to design the forming scheme and process parameters first, and often do not know how to use the analysis results to guide production after analysis. To a certain extent, this has affected the promotion and popularization of CAE software. In order to play a greater role in CAE software, HsCAE 6.10 successfully introduced artificial intelligence technology. In the simulation system, the parameters with continuous value space, such as injection time and injection temperature, are optimized by the method of artificial neural network, and the interpretation and evaluation of the analysis results are processed by the method of rule-based reasoning.
There are two lights on the power supply of NC machining center unit, one is the power indicator light, which is green; the other is the power alarm light, which is red. The power supply unit here includes the power input unit and the power control part.
When the power of CNC machining center cannot be connected, if the power indicator light (green) is not on.
Fuse F1 and F2 of power supply unit have been blown. This is caused by high input voltage, or the components of the power supply unit itself are damaged.
The input voltage of CNC machining center is low. Please check the voltage entering the power supply unit. The allowable voltage is AC 200V + 10%, 50Hz ± 1Hz.
The power supply unit is poor, and there is damage in the unit
The power indicator light is on and the alarm light disappears, but the power cannot be connected.
This is because the power on condition is not met. By the following switch circuit, the conditions for power on are as follows:
There are three conditions for turning on the power supply of CNC machining center: (1) the source on button is closed. Dongguan Mechanical parts processing (2) power off button is closed. (3) The external alarm contact is open.
In the process of using CNC machining center, there may be tool imbalance. If not adjusted in time, the processing effect will be affected. Therefore, we should always pay attention to the tool balance of CNC machining center. The main reasons for the imbalance of the tool handle are the asymmetry of the tool design, the defects in the tool body, and all the adjustments on the tool. The tool with correct balance can significantly reduce the noise and vibration, which can increase the tool life and improve the accuracy consistency of parts.
The centrifugal force of CNC machining center magnifies the vibration caused by unbalance in proportion to the square of speed. The vibration of CNC machining center caused by this increase minimizes the life of bearing bush, bearing, shaft, spindle and gear.
Before balancing the tool in CNC machining center, it is necessary to measure the unbalance and the angle position of each selected correction plane. These variables are measured on two general types of balancing machines: non rotating or gravity machines for measuring single plane imbalance, and rotating or centrifuge for measuring single plane or two plane imbalance.
After determining the magnitude and angle of the unbalance in the correct plane, you can correct it by adding or removing material from the workpiece. Machining center for components that are not tools, the most widely used material adding method of drilling and tapping center is to weld the counterweight on the components. Other methods for components with slight unbalance include adding solder to the component body or adding weight in pre drilling.
