Dongguan CNC Precision Machining Factory Should Learn to Choose Processing Methods and Content Based on Processing Characteristics

The process design of Dongguan CNC Precision Processing Factory must be completed before the programming work begins, because programming only has a basis after the process plan is determined. The quality of the process plan not only affects the efficiency of the machine tool, but also directly affects the processing quality of the parts. Analyze based on a large number of machining examples. Inadequate consideration of process design is one of the main reasons for CNC machining errors

Therefore, it is necessary to conduct process analysis and planning before programming. The CNC machining process design mainly includes the following contents:

(1) Select parts suitable for machining on CNC machine tools and determine the process content

(2) Analyze the drawings of the processed parts, clarify the processing content and technical requirements, and determine the processing plan of the parts. Develop a CNC machining process route. Such as dividing processes, connecting processing with non CNC machining processes, etc

(3) Design of processing procedures and steps. For example, selecting the positioning reference for the parts, determining the fixture and auxiliary tool scheme, and determining the cutting amount.

(4) Adjustment of CNC machining program. Select the tool alignment point and tool change point, determine tool compensation, and determine the processing route

(5) Allocate machining allowance in CNC machining.

(6) Process some process instructions on CNC machine tools.

(7) First piece trial processing and on-site problem handling.

(8) Finalization and archiving of CNC machining process documents at Dongguan CNC Precision Processing Factory.
