Becoming a CNC machining master must go through the process

1. Simple CNC machining programming

Will use the coordinate system, know the relationship between the machining coordinates and the design coordinates. Familiar with 2D toolpath, contour, parallel machining, 3D equidistant machining, can segment shallow and steep surfaces, understand the relationship between tolerances and allowances, understand the calculation of the boundary of the machined surface, understand the calculation of the dividing line of shallow and steep surfaces, understand the surface roughness degree of control. Know the post-processing methods of three control systems, be familiar with ISO codes, and be able to program manually. Understand the structure of the mold, and will dismantle the copper male. Familiar with cutting parameters of commonly used tools. Familiarize yourself with the effect of the hardness of the cutting material on the parameters. I can barely write a complete knife path, I can't control the second roughing, and I don't have a deep understanding of the light knife. The software you understand is just a tool for expressing your thoughts, and you are willing to learn more about metal cutting technology, tools, materials, products and molds themselves.

2. Simple CNC programmer

On the basis of 'one', with one month's experience, I can basically complete the processing of soft materials, such as copper males, and the size is basically accurate. Basically, it can process simple two-dimensional steel materials and be familiar with the process, and can control the error within a wire.

3. Junior CNC programmers

On the basis of 'one' and 'two', the next tool path can be written against the processing result while writing, and the tool path can basically be accurately cut to the desired cutting height or shape. Knives are relatively small. The rhythm of the knife path is relatively smooth. The tool path is cumbersome, the thinking is not very clear, and there are many places for repetition and waste.

Fourth, the need for mold engineers to lead the work

In the first three heights, it is possible to write out the three-dimensional tool path without looking at the machining results of the machine tool independently, without major problems, and post-processing it smoothly, and modify the program in the event of a power failure. Basically, it is impossible to separate the mold independently, and it needs to rely on the mold engineer or the 2D drawing of the mold structure. Have a certain understanding of tool rebound, broken tool, overcut, corner problem, light not in place, etc. There are still more empty knives. But the understanding of the software parameters has been in-depth.

Five, basically able to work independently, but the speed is slow

The software operation is relatively proficient, but the speed is not very fast. It can be independently divided into simple molds including five basic mold structures, and can be easily handled by hand. There are not many problems, the processing is basically in place, but the processing effect is average, not very beautiful. The amount of retention is uneven, the interface between the two tool paths is not smooth, and the polishing is difficult.

6. Basic ability to work proficiently

The software is proficient, the shortcut keys are proficient, the operation is smooth and smooth, the mold assembly is understood, how the machining surface allowance matches the mold assembly, the product problems caused by the machining surface allowance and the future assembly problems of the product, and how to process conservatively To prevent future mold assembly and product structure and assembly problems.

Familiar with data security. Know how to machine the positioning of a product that needs to be machined on all six sides. Know how to cut copper bars and steel materials that are easily deformed. Learn how to map residual material to save time or prevent tool bumps on molds that have been roughed half-opened with a milling machine.

7. Ability to handle problems independently

Be able to face product design problems and actively change product design to meet the rationality of mold structure and processing. It can accurately calculate the processing time, and can face the quotation for CNC processing of the product. Accurate calculation of design costs and processing costs. Good at communicating with customers. Able to cut out drawings. Copper public positioning drawings. Will dismantle uncomplicated copper males.

8. Be able to effectively communicate with various departments and deal with it and have work experience in large companies

Familiar with the software, can dismantle complex copper males, can determine copper males, be familiar with copper males to avoid voids, integrate several copper males to reduce material costs, and produce positioning diagrams. A copper male that can do a rotating body. Distortions due to data input and output are repaired. Familiar with mold price, mold base customization, thimble position, hot runner. At a certain height, control the whole thinking and various problems encountered in the process from product parts to assembly to deformation to mold. Familiar with the expression of mold coordinates and assembly coordinate system in drawings, so that all departments of the company can fully share data, can quickly reflect the relationship between parts assembly and mold positioning, quickly find out key dimensions, and clarify the key to be expressed in engineering drawings. Data, know that those don't need to be expressed.
