I. Simple CNC Machining Programming Assistant

Proficient in using coordinate systems and understands the relationship between machining coordinates and design coordinates. Familiar with 2D toolpaths, including contouring, parallel machining, and 3D equidistant machining. Can split shallow and steep surfaces, understands the relationship between tolerances and allowances, knows how to calculate machining surface boundaries, and is aware of the calculation of shallow-steep surface split lines. Has knowledge of surface roughness control methods. Capable of post-processing for three types of control systems, familiar with ISO codes, and can perform manual programming. Understands mold structure and can perform copper electrode decomposition. Familiar with cutting parameters for common tools. Understands the impact of workpiece material hardness on cutting parameters. Can barely generate complete toolpaths but lacks control over secondary roughing. Has an insufficient understanding of finishing operations. Views software merely as a tool for expressing ideas and is willing to deeply study metal cutting processes, tools, materials, products, and molds themselves.

II. Simple CNC Programmer

Dongguan Changyuanfeng Precision CNC Factory believes that, based on becoming a CNC machining programmer and with one month of experience, one can basically complete the machining of soft materials such as copper electrodes with relatively accurate dimensions. They can also basically process simple two-dimensional steel materials, be familiar with the workflow, and control errors within one thread. However, to produce high-quality precision aluminum parts, automotive components, precision camera parts, remote control casings, etc., through CNC machining, one still needs to improve themselves to become a CNC programmer.

III. Entry-Level CNC Programmers

Building on the foundations of 'One' and 'Two', they can write the next toolpath while referring to the machining results, with the toolpath generally able to accurately cut to the desired height or shape. The amount of air cutting is relatively small. However, the rhythm of the toolpath is somewhat weak. The toolpath is cumbersome, the thinking process is not very clear, and there are many repeated and wasteful areas.

IV. Requires Guidance from Mold Engineers

At the first three levels of proficiency, one should be able to independently generate 3D toolpaths without referring to machine tool processing results, ensuring no major issues, and successfully complete post-processing. They should also be capable of modifying programs in cases such as power outages. Basic mold splitting cannot be done independently and requires reliance on mold engineers or 2D mold structure drawings. There is a certain understanding of issues like tool deflection, tool breakage, overcutting, corner problems, and insufficient finishing. There are still relatively many air cuts, but there is a deep understanding of software parameters.

V. Basically capable of working independently, but at a slower pace. The software operation is relatively proficient, though not very fast. It can independently handle simple molds including five basic mold structures and can mill simple hand models. There are few issues, and the processing is basically in place, but the processing effect is generally average and not very attractive. The material allowance is uneven, the two toolpaths do not connect smoothly, and polishing is difficult.

VI. Basically able to work proficiently

Proficient in software and shortcuts, with smooth and efficient operations. Understands mold assembly, knows how the allowance on machined surfaces coordinates with mold assembly, is aware of product issues caused by machining allowances and the subsequent assembly problems they may lead to in the future, and knows how to adopt conservative machining to prevent future mold assembly and product structural and assembly issues. Familiar with data security. Knows how to position workpieces that require machining on all six faces. Understands how to approach cutting for easily deformed copper electrodes and steel materials. For molds that have been semi-rough milled on a milling machine, knows how to measure residual material to

VII. Ability to Handle Issues Independently

Capable of addressing product design issues proactively, modifying product designs to ensure the rationality of mold structure and processing. Able to accurately calculate processing time and provide quotations for CNC machining of products. Accurately calculates design and processing costs. Skilled in client communication. Can produce wire cutting drawings and copper electrode positioning drawings. Proficient in decomposing simple copper electrodes.

Eight. Able to effectively communicate with various departments, handle issues, and possess experience working in large companies. Proficient in software, capable of decomposing complex copper electrodes, determining material for copper electrodes, familiar with air clearance for copper electrodes, integrating multiple copper electrodes for production to reduce material costs, and generating positioning diagrams. Skilled in creating copper electrodes for rotational parts. Able to repair deformations caused by data input and output. Familiar with mold pricing, custom mold frames, ejector pin positions, and hot runner systems. Capable of controlling the overal lLine of thought from product parts to assembly, deformation, and mold at a certain level, as well as addressing various issues encountered in the process. Familiar with the representation of mold coordinates and assembly coordinate systems in drawings, enabling full data sharing among company departments, quickly reflecting part assembly and mold positioning relationships, quickly identifying critical dimensions, clearly defining key data to be expressed in engineering drawings, and knowing what does not need to be expressed.
