Product Description

CNC machining of hardware parts


The programming methods of NC machining are divided into manual (manual) programming and automatic programming. Manual programming, the entire content of the program is manually written according to the instruction format specified by the CNC system. Automatic programming is computer programming, which can be divided into automatic programming methods based on language and painting. However, no matter what kind of automatic programming method is adopted, corresponding hardware and software are required.


Part machining accuracy


1. We know that precision machining requires high precision. Precision machining has good rigidity, high manufacturing precision, and accurate tool setting, so it can process parts with high precision requirements. It is impossible for precision parts processing to complete all the processing contents of all surfaces in one process. The entire processing process of precision parts processing can be divided into the following stages:

(1) Roughing stage. Most of the machining allowance of each machined surface is removed, and the fine reference is machined, and the main consideration is to increase the productivity as much as possible.

(2) Semi-finishing stage. To remove the defects that may occur after rough machining, to prepare for the finishing of the surface, it is required to achieve a certain machining accuracy, ensure an appropriate finishing allowance, and complete the machining of the secondary surface at the same time.

(3) Finishing stage. At this stage, high cutting speed, small feed and cutting depth are used to remove the finishing allowance left by the previous process, so that the surface of the part can meet the technical requirements of the pattern.

(4) Finishing stage. It is mainly used to reduce the surface roughness value or strengthen the machined surface. It is mainly used for surface machining with high surface roughness requirements (ra≤0.32 μm).

(5) Ultra-precision machining stage. The processing accuracy is 0.1-0.01μm, and the surface roughness value ra≤0.001μm is in the processing stage. The main processing methods are: precision cutting, fine mirror grinding, precision grinding and polishing.

CNC machining of hardware parts
It can be seen that the realization of CNC machining programming is the key. But programming alone is not enough. CNC machining also includes a series of preparations that must be done before programming and the aftermath of programming. Generally speaking, the CNC machining process mainly includes the following contents:


(1) Select and determine the parts and contents for CNC machining;
(2) Process analysis of CNC machining of parts drawings;
(3) Process design of CNC machining;
(4) Mathematical processing of part drawings;
(5) Write the processing program list;
(6) Make control medium according to the program list;
(7) program verification and modification;
(8) First piece trial processing and on-site problem handling;
(9) The finalization and filing of CNC machining process documents.


1. Reasonable selection of machine tools
When machining parts on CNC machine tools, there are generally two situations.
The first case: there are part drawings and blanks, and a CNC machine tool suitable for processing the part should be selected.
The second case: there is already a CNC machine tool, and parts suitable for processing on the machine must be selected. In either case, the main factors to be considered are the material and class of the blank, the complexity of the contour shape of the part, the size, the machining accuracy, the number of parts, and the heat treatment requirements.


To sum up, there are three points:
①It is necessary to ensure the technical requirements of the processed parts and process qualified products.
②Conducive to improving productivity.
③ Reduce production costs (processing costs) as much as possible.

Process analysis
The NC machining process of the parts to be processed involves a wide range of issues. The following combined with the possibility and convenience of programming propose some main contents that must be analyzed and reviewed.
1. Dimensions should conform to the characteristics of CNC machining
In NC programming, the dimensions and positions of all points, lines and surfaces are based on the programming origin. Therefore, it is best to give the coordinate dimensions directly on the part drawing, or try to quote the dimensions with the same datum.
2. The conditions of geometric elements should be complete and accurate
In programming, programmers must fully grasp the geometric element parameters that constitute the part outline and the relationship between the geometric elements. Because all geometric elements of the part contour need to be defined during automatic programming, and the coordinates of each node need to be calculated during manual programming, no matter which point is unclear or uncertain, programming cannot be performed. However, due to the lack of consideration or neglect by the part designers in the design process, the parameters are often incomplete or unclear, such as whether the arc and the straight line, the arc and the arc are tangent, intersecting or separating. Therefore, when reviewing and analyzing the drawings, you must be careful and contact the designer in time if you find any problems.


1. Precautions before starting the machine
(1) The operator must be familiar with the performance and operation method of the CNC machine tool. The machine tool can only be operated with the consent of the machine tool management personnel.
(2) Before powering on the machine tool, check whether the voltage, air pressure and oil pressure meet the working requirements.
(3) Check whether the movable part of the machine tool is in normal working condition.
(4) Check whether the workbench is offside and exceeds the limit state.
(5) Check whether the electrical components are firm and whether there is any disconnection.
(6) Check whether the ground wire of the machine tool is reliably connected to the ground wire of the workshop (it is especially important to start the machine for the first time).
(7) Turn on the main power switch only after the preparations before starting the machine have been completed.


2. Precautions during the startup process
1) Strictly follow the startup sequence in the machine manual.
2) Under normal circumstances, the machine tool reference point return operation must be performed first during the startup process, and the machine tool marking system must be established.
3) After the machine is turned on, let the machine tool run for more than 15 minutes, so that the machine tool can reach a balanced state.
4) After shutting down, you must wait for more than 5 minutes before restarting. Unless there are special circumstances, it is not allowed to frequently start or shut down.
3. Notes on debugging process
1) Edit, modify and debug the program. If the first piece of trial cutting must be dry run, to ensure that the program is correct.
2) Install and debug the fixture according to the process requirements, and remove the iron filings and sundries on each positioning surface.
3) Clamp the workpiece according to the positioning requirements to ensure correct and reliable positioning. The workpiece shall not be loosened during processing.
4) After installing the tool to be used, if it is a machining center, the tool position number of the tool on the tool magazine must be strictly consistent with the tool number in the program.
5) Set the tool according to the programmed origin on the workpiece to establish the workpiece coordinate system. If multiple tools are used, length compensation or tool nose position compensation will be performed on the remaining tools respectively.
3D simulation CNC machining broadcast
3D technology can make the operation of CNC machine tools more accurate, avoid instrument damage, and ensure the accuracy and efficiency of product processing. Through a series of complex algorithms, the working trajectory of the model is calculated, and the simulated CNC machining such as metal processing and metal cutting is realized.
