Introduction

This standard applies to the carbide cutting tool for face milling, which is a major machining method. As shown in Figure 1.

Figure 1 Face milling cutter face milling

The methods recommended in this standard are suitable for both laboratory and factory applications. The purpose is to unify steps when cutting tools, workpiece materials, Cutting parameters and cutting fluid for comparison, can improve the reliability and comparability of test results. In order to achieve this as much as possible, this standard package Including the recommended reference materials and conditions, should be practically used.

In addition, the recommended values in the standard can be used to help determine the recommended cutting data, or to determine the limiting factors and some processing characteristics, such as cutting the properties of the machined surface and the shape of the chip. Especially for the purposes described above, even if this standard has given some of the recommended values Number, which may have to be used as a variable.

The recommended test conditions for this standard apply to face milling tests for steels and castings with normal metallographic properties. But if it is appropriate this standard can also be applied to other materials or for the special purpose of the tool developed by the end of the milling test.

The accuracy of the recommended values should be considered the minimum requirement. Any deviation from the recommended value should be specified in the test report.

Note. This standard is not provided for acceptance test, nor for such use.

Face milling cutter life test

1 Scope

This standard specifies the recommended procedure for the milling of steel and cast iron pieces in the life test of cemented carbide face mills. It applies to laboratories and students Production reality.

Face milling can be considered for the following two types of cutting conditions.

a) the conditions under which the tool is primarily due to wear and tear;

b) The tool is mainly due to other phenomena, such as cutting edge fracture or plastic deformation failure conditions.

This standard only considers the recommended values for tests based on tool wear.

The test of the second type of condition is under study.

This standard specifies the tool life test as shown in Figure 1, the following factors. the workpiece, tool, cutting fluid, cutting Cutting conditions, equipment, tool failure and tool life evaluation, test procedures, and record, evaluation and reporting of results.
