CNC as a CNC machining equipment, has more advantages than traditional machining equipment. In the process of CNC machining, CNC machining is better, both in terms of product machining accuracy and machining efficiency. For the control and management of production quality is strictly divided into the following points:

(1) Improvement of product machining processability

  The processing cost of the product has a direct relationship with its structure of the process, the product's processing technology determines its processing cost, but also limits the processing efficiency and capacity. Therefore, from the perspective of product design, as far as possible to reduce the difficulty of its machining process, which can reduce processing costs, shorten the CNC machining time, improve the quality of machining and machining efficiency, and ultimately enhance the capacity of the CNC.

(2) CNC system for tool life management control

CNC system life management control of the tool is to calculate the number of times the tool is machined, or machining time is determined. Therefore, when the tool life reaches the expected number of times or time specified by the system, the CNC will automatically stop the action. If manual monitoring is not in place to replace the tool or reset the tool life in advance, the CNC's machining capacity is affected. Therefore, tool life is a key factor affecting spindle utilization. Especially when a product has many CNC machining processes, large machining volume, and high dimensional accuracy requirements, more types of tools will be required. At this time, the CNC tool magazine automatically replace the tool, as well as the tool action is more frequent, and the tool wear is larger, thus making the manual tool change, adjust the machine more frequently. Therefore, tool wear is an important indicator that affects the normal production beat and capacity of CNC.

(3) CNC program and process parameters optimization

In the process of product processing technology to determine the process, should fully consider the CNC and other CNC machine tools, all the functions, in order to shorten the processing route, reduce the number of times and the number of times the tool change, so as to enhance production capacity. Through the selection of reasonable cutting dosage, give full play to the cutting performance of the tool, optimize the CNC machining process parameters to ensure that the spindle high-speed machining, in order to reduce the CT time of the parts processing, and ultimately improve the efficiency of the product processing and improve the quality of production.

(4) Optimization of CNC machining process method

In the preparation of CNC machining process, should not only focus on the feasibility of processing, should also focus on the development of the machining process on the impact of machining efficiency. Through the rational allocation of machining process sequence, reduce the number of tool changes, can effectively shorten the CNC machining time, improve production capacity.

(5) Strict control of production site management

In the CNC machining production process must be developed and strictly implement the production operation SOP, in order to standardize the manual operation action, reduce the phenomenon of passive idleness as well as the occurrence of unnecessary action time waste. Set up an incentive system to improve the operator's motivation to improve production capacity and product quality.

(6) Timely logistics

Production process to be processed products can not be timely in place, resulting in CNC spindle stops, thus affecting production capacity. There are many factors affecting the timeliness of the processing of products to be processed, among them, the lack of vigilance of the logistics staff, CNC operators passive, as well as the layout of the workshop and the logistics system is unscientific and unreasonable, the capacity of each process does not match the upper section of the incoming material in a timely manner and other issues will affect the CNC's capacity to play. In the workshop production layout planning, the product completion area and to be processed area should be as close as possible to the CNC, in order to minimize the waste of time when the operator picks up and puts down the product. Considering the frequent wear and tear of tools, each CNC should have a certain amount of tools with products to reduce the waste of equipment waiting by manually going to the tool magazine to coordinate the tools.

(7) Detailed inspection of CNC machining abnormality

Frequent inspection of equipment and fixture conditions, to reduce the CNC itself potential abnormalities, as well as to ensure that the work fixture on the cylinder, solenoid valves, motors and other electrical components in the oil environment, in order to reduce the occurrence of production interruptions of the CNC spindle to improve the utilization of the spindle.

(8) Standardization of workshop production layout

Lean workshop production layout is an important research area in the discipline of industrial engineering, so that the enterprise's resources (human, financial and material resources, etc.) to get the most reasonable and effective allocation of rows and matches (the formation of logistics, value flow), to fundamentally improve the enterprise's production efficiency, so as to reduce the cost of logistics and production costs, reduce inventories, and ultimately make the workshop production to multi-species, small quantities, and the transformation of the flexibilization mode of production.
