How to Build the Process Flow of a CNC machining Part

As a computer numerical control manufacturing process, CNC machining has revolutionized the production of complex parts and components. It is crucial to have a well-defined process flow chart outlining each step to ensure smooth and efficient manufacturing processes.

Analysis of Technical Drawing and Its Manufacturability
When analyzing the part technical drawing for machining, there are two parts to consider: the part drawing itself and the structural processability of the part. The information from the drawings will guide the tool selection and cutting parameters for each machining operation.

Determine the CNC machining content of the parts
In most cases, CNC machining operations cannot do all machining processes for a part, and only some parts of the process are suitable for CNC machining. Therefore, it is necessary to analyze the part structure carefully to choose the most appropriate and essential content and strategies for CNC machining. When selecting the content, it is required to consider the equipment of the machine shop and focus on solving problems, overcoming key issues, and improving production efficiency to take advantage of the benefits of CNC machining fully.

Determine the CNC machine capabilities
Next, you will need to identify the CNC machine used to manufacture the part and determine its capabilities. This includes the maximum spindle speed, tool capacity, and axis movements. Knowing the machine's capabilities will help you decide which cutting tools can be used, the cutting parameters that can be achieved, and the optimal machining sequence.

The Selection of Cutting Tools on CNC Machines
Selecting the appropriate cutting tool for CNC milling tools depends on several factors, such as the part's material and size, the machining operation, and the cutting conditions.

Design of CNC Machining Process Route
The difference between designing process routes for CNC machining and general machine tool(Non-NC machining) processing is that the former only describes specific CNC machining operations rather than the entire process from blank to finished product. It is important to note that CNC machining operations are interspersed throughout the whole part manufacturing process and must be well connected with other machining processes. The common process flow diagrams below show how this works.

CNC machine parts how to maintain

Daily inspection
The main projects include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, pressure system. Daily inspection is based on the normal condition of the system to be detected.

Weekly inspection
Its main items include machine tool parts and spindle lubrication system, which should be checked correctly every week, especially for machine tool parts to remove iron scraps and clean external debris.

Monthly inspection
Mainly to check the power supply and air dryer. The power supply voltage should be measured and adjusted if the rated voltage is abnormal under normal conditions. Air dryers should be removed once a month and then cleaned and assembled.

Seasonal inspection
Mainly from the machine bed, hydraulic system, spindle lubrication system three aspects of the inspection. For example, to check the machine bed, mainly to see whether the accuracy of the machine tool, the level of the machine tool meets the requirements in the manual, if there is a problem, should immediately contact the mechanic.

Semi-annual inspection
After half a year, the hydraulic system of the machine tool, the spindle lubrication system and the X-axis should be checked. If there is any problem, new oil should be replaced and cleaned.
