How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Pentagram 3D modeling

1. Draw a pentagram.

Click the button on the curve generation toolbar to enter the drawing state of the spatial curve. In the instant menu below the feature tree, select the circular method “Center Point_Radius” and follow the prompts to click the origin of the coordinate system or press Enter. In the pop-up dialog box, enter and confirm the coordinates of the center point (0,0,0) and radius R = 100, and click the right mouse button to finish drawing the circle.

Note: When inputting the coordinates of the point, it should be input under the status of English input method. Otherwise it will result in an error.

2. Draw a pentagon.

Click the button on the curve generation toolbar, select Center in the direct menu below the feature tree, make sure the number of edges is 5, and connect internally. Follow the system prompts to get the center point. The inner radius is 100 (the input method is the same as for pie charts). Right-click to end the pentagonal figure. So we got a pentagram. As shown below

3. Contour pentagram configuration

With the above operation, I used the straight line button on the curve generation toolbar to get the 5 corners of a 5-star star. In the direct menu below the feature tree, select 2-dotted line, continuous, non-orthogonal (as shown) to connect the corners of the five-star corners. As shown below.
Overview of the pentagram

Use the delete tool to remove the extra line, click the button and click the button to add the line. The picked line will turn red, then click the button on the right to confirm.

4. The space frame is composed of pentagrams.

When constructing a space frame, we also need the vertices of the pentagram. So we need to find the height position (0,0,20) of the pentagram, which can be achieved at two points in such a space frame structure.

Use the buttons on the toolbar to generate linear curves, select “2 rows”, “Continuous”, select “Non-Orthogonal” from the direct menu below the feature tree, and use the mouse to click on the corners of the pentagon. To do. Then click Enter and enter the vertex coordinates (0,0,20).
Similarly, the connections between the vertices of a five-star star complete the spatial wireframe of the five-star star.

Pentagram surface formation

(1) Create a surface from a ruled surface.

As an example, take a five-star horn. Click the Ruled Surface button on the Surface toolbar and click the Curve + Curve option in the Instant Menu under the feature tree to generate a scribed surface. Then use the left mouse button to select the two lines adjacent to the corners to complete the surface.

(2) Generate surfaces for other corners.

When you generate other surfaces, you can either use regular surfaces to generate the surfaces one at a time, or use the array function to perform an array of circular surfaces with corners to create a five-star surface. Can be realized in combination. Click the button on the Geometry Conversion Toolbar and select Loop Array Mode from the feature tree shortcut menu. The distribution pattern is “equal distribution” and the number of copies is “5”. Use the left mouse button to select the two corner surfaces and click the right mouse button to confirm. Follow the prompts to enter the coordinates of the center point (0,0,0). Also, when you use the mouse to select the coordinate origin, the system automatically generates a surface for each corner. As shown below.

Note: When selecting adjacent lines, you should pick up the mouse as consistently as possible (corresponding position) to get the correct scored face.
Note: When using a circular array, be careful about choosing the array plane. Otherwise, you will get an array error in the array. Therefore, it is recommended to press the “F5” shortcut to verify that the array plane is the XOY plane before using the array in this example.

(3) Create a profile surface treatment for the pentagram.

The circle is centered on the origin and has a radius of 110. Click the Flat tool button on the Surface toolbar with your mouse and select Cut Plane from the Immediate menu below the feature tree. When you use the mouse to select a plane contour and determine the chain search direction (with the mouse pointer), the system prompts you to select the first internal contour and the mouse to select the bottom line of the star. Click the right mouse button to use and confirm. Complete the contour surface. As shown below.

Generate a processing entity

  • (1) Generate a primitive. Select the XOY plane in the feature tree, click the right mouse button and select Create Sketch as shown. Alternatively, click the “Create Sketch” button (press the shortcut key F2) to enter the sketch state.Click the Curve Projection button on the Curve Generation toolbar and use your mouse to select an existing contour circle and project the circle onto your sketch as shown. Click the Extend Feed button on the Features toolbar and select the appropriate option in the Stretch dialog box as shown.
  • (2) Use the surface to cut the material to create a solid.Click the Cursor Cut button on the feature toolbar and use the mouse to select each existing surface, then select the material removal direction. Click OK and you’re done as shown.
  • (3) Use the hide function to hide the surface. Click to select Edit-Hide, use the mouse to select the entity from right to left (select a single face with the mouse), right click to confirm, and the physical song Is hidden. As shown.

Surface cutting

First, set rafting parameters

  • 3. Select the machining contour according to the system prompt.Select the rectangle for which you want to set the processing area and click the chain search arrow. The system prompts all surface pickup “pickup processing surface”, select the entire surface, the system entity turns red, then press the right edge.
  • 4. Generate a roughing toolpath.Tip: The system will automatically generate a rough trajectory, such as “Prepare the surface” or “Surface treatment”.
  • 5. Hide the generated rough track.Pick up the truck. Right-clicking on the pop-up menu and selecting the Hide command to hide the resulting rough path facilitates the next step.

Second, fine machining parameter setting

  • 1. Set “Complete parameters.” Click [Apply]-[Track Generation]-[Scanline Trimming] and set “Trimming Parameters” in the pop-up menu “Trimming Parameter Table”. As shown below.
  • 2. Set the finishing “mill cutter parameters”.
  • 3. Follow the system prompt to pick up the entire part surface as the machined surface and press the right button to confirm. The system prompts you to “pick up the interfering surface”. If the part has no interference surface, press the button on the right to confirm the skip. The system will continue to display the “Pick Outline” prompt, use the mouse to pick up the outline of the part directly, right-click to confirm, and select the chain search direction to determine.
  • 4. Orbit generation is completed. As shown below.Note: Processing margin for finishing = 0.

5, machining simulation, toolpath inspection and correction

  • (1) Press “Visible” Ammonium to see all the rough / finishing tracks generated.
  • (2) Click [Application]-[Trajectory Simulation] and select an option in the Immediate Menu as shown. Press the right key, depending on the system instructed to pick up the orbit of the roughing tool and finish the orbit. The system performs simulation processing.

6, Observe the simulated machining path and test to determine if the correct tool path is valid (with or without overcuts and other errors).
7. Click Applications-Edit Track to open the Edit Track table. Follow the prompts to select the corresponding machining path or corresponding track point and change the corresponding parameters to modify the local track. If the change is too large, you will need to regenerate the machining path.
8. After the simulation test is done correctly, you can save the roughing / finishing track.
