What is the promotion path of a CNC machining operator

What is the promotion path of a CNC machining operator?

When we become a CNC machining operator, it is not that we can do any operation without learning. In fact, this is the beginning and the beginning. After many years of CNC machining operations, in summary, the promotion of a CNC machining operator has the following levels. Let’s take a look.

1. Simple CNC machining programmer
First, the coordinate system will be used to know the relationship between the processing coordinates and the design coordinates. Familiar with two-dimensional toolpaths, familiar with contour, parallel machining, three-dimensional equidistant machining, can segment shallow and steep surfaces, understand tolerance and maintenance relations, understand the calculation of the boundary of the processing surface, understand the calculation of the tangent of the shallow steep surface, and understand the surface Roughness control method.. Know the post-processing methods of three control systems, familiar with ISO code, and manual programming. Understand the mold structure and remove the copper male. Familiar with the cutting parameters of commonly used tools. Familiar with the influence of cutting material hardness on parameters.. Barely able to write a complete tool path, unable to control the secondary roughing, and do not have a deep understanding of the light knife. Understand that software is just a tool for expressing ideas, and I am willing to conduct in-depth learning of metal cutting processing, tools, materials, products and molds themselves.

 

2. Simple CNC programmer
On the basis of “one”, after one month of experience, I can basically complete the processing of soft materials, such as copper, and the size is basically accurate. Basically be able to process simple two-dimensional steel and be familiar with the process flow, and can control the error in a wire.

 

3. Junior CNC programmer

On the basis of “one” and “two”, the next cutting path can be written on the machining result while writing. The cutting path can basically be cut to the required cutting height or shape accurately. The empty knife is smaller. The pace of the knife path is more similar. The knife path is cumbersome, the idea is not very clear, and there are many repeated wastes.

 

Four, mold engineers are required to lead the work
At the first three heights, the three-dimensional tool path can be written independently without looking at the machining results of the machine without major problems, and then processed smoothly, and the program can be modified in the event of a power failure. Basically, the mold cannot be separated, and it is necessary to rely on the mold engineer or the 2D drawing of the mold structure. Have a certain understanding of tool rebound, cutting, over-cutting, corner problems, lack of light, etc.. There are still many empty knives.. But the understanding of software parameters has always been more in-depth.

 

5. Basically able to work independently, but at a slower speed
The software operation is relatively proficient, but the speed is not very fast. It can separate a simple mold including five basic mold structures, which can be simple hands. There are not many problems, and the treatment is basically in place, but the treatment effect is average and not very beautiful.. The retention is uneven, the two-way interface is not smooth, and the polishing is difficult.

 

6. Basically able to work proficiently
Proficient in software, skilled in shortcuts, operating flow, knowing mold assembly, knowing how the reservation of the machining surface matches the assembly of the mold, knowing the product problems caused by the reservation of the machining surface, which will lead to future product assembly problems, and knowing how to conservatively process to prevent mold assembly and Future product structure and assembly issues.. Familiar with data security.. Know how to locate products that need to be processed in all aspects.. Know how to cut copper strips and steels that are easily deformed.. Know how to measure residuals when using a milling machine for semi-open rough molds. Material, save time or prevent knife collision.

 

7. Ability to deal with problems independently
Be able to face the problem of product design and actively change product design to meet the rationality of mold structure and processing. Be able to accurately calculate the processing time and be able to face the quotation of CNC machining products. Accurate calculation of design costs and processing costs. Good at communicating with customers.. Be able to cut and draw lines.. Produce copper public positioning drawings.. Take the whole thing out.

 

8. Ability to effectively communicate and handle departments, with experience in large companies
Familiar with the software, able to dismantle complex coppers, order materials for coppers, be familiar with the avoidance of coppers, integrate production of several coppers to reduce material costs, and draw out a positioning map. Who can become a spinner. The deformation due to data input and output will be repaired. Familiar with mold price, mold base customization, thimble position, hot runner.

 

Various problems encountered in the thought and process of controlling the entire product parts to the assembly to the deformation to the mold at a certain height. 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 part assembly and mold positioning, quickly find key dimensions, clarify the key data to be expressed in engineering drawings, and know those who do not Need to express.
