When programming CNC lathes, it is very important to choose the correct CNC tool. cnc CNC lathe machining tool's general requirements are easy installation and adjustment, good rigidity, high precision and durability. On this basis, the cutting performance of the workpiece material, the processing capacity of the machine tool, the type of CNC machining program, cutting parameters and many factors related to the working range of the machine tool and CNC device are taken into account.
In selecting the type and specification of the tool, the influence of the following factors is taken into account.
(1) Nature of production
The nature of production in this context refers to the batch size of the part, and the impact on tool selection is considered mainly in terms of machining costs. For example, the use of special tools in mass production may be cost-effective, while in single or small batch production, the choice of standard tools is more suitable.
(2) Machine type
The influence of the CNC machine tool used to complete the process on the type of tool selected (drill, turning tool or milling tool). Under the condition of being able to ensure good rigidity of the workpiece system and tool system, it is allowed to use high productivity tools, such as high-speed cutting turning tools and large feed turning tools.
(3) CNC machining program
Different CNC machining programs can use different types of tools. For example, the hole processing can be used to drill and reaming drill, but also available to drill and boring tool to process.
(4) the size and shape of the workpiece
The size and shape of the workpiece also affects the choice of tool type and specifications, such as special surfaces to use special tools to process.
(5) Surface roughness
Surface roughness affects the structure of the tool shape and cutting amount, for example, rough milling of blanks, coarse-tooth milling cutters can be used, fine milling with fine tooth milling cutters.
(6) Machining accuracy
Machining accuracy affects the type and structure shape of the finishing tool, for example, the post-processing of the hole according to the accuracy of the hole available drill, reaming drill, reamer or boring tool to process.
(7) Workpiece material
Workpiece material will determine the choice of tool material and cutting part geometric parameters, tool material and workpiece machining accuracy, material hardness and other related.
