Embodiment Construction

[0043] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0044] refer to figure 1 , a preferred embodiment of the present invention provides a method for machining an internal thread of a blind hole without an undercut, comprising the steps of:

[0045] Step S100 , obtaining the thread processing specification parameters of the blind hole to be processed.

[0046] The CNC machine tool obtains the artificially input thread processing specification coefficient of the blind hole to be processed through the human-computer interaction interface. The thread processing specification parameters include the thread specification size, thread material, and thread profile angle. The size of the thread includes the nominal diameter of the thread, tooth depth, p...

Abstract

The invention discloses a method for machining an internal thread of a blind hole without a tool withdrawal groove. The method comprises the steps that the machining specification parameter of the thread of the blind hole to be machined is obtained; a corresponding tool is selected and the cutting allowance is obtained according to the machining specification parameter of the thread so that the cutting feeding distance can be determined, and the initial position of the cutting feeding distance is located at an opening of the blind hole to be machined; and the thread is machined on the blind hole to be machined through the tool according to the cutting feeding distance. According to the method for machining the internal thread of the blind hole without the tool withdrawal groove, the thread machining precision is improved, and the quality of the thread is improved; the service life of the tool is prolonged, and the use cost of the tool is greatly reduced; machining efficiency is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an internal thread processing method for a blind hole without an undercut. Background technique [0002] CNC turning thread is widely used in the field of thread processing, but the processing technology for precision internal thread of blind hole without undercut is still immature. Since there is no relief groove in the inner hole, the cutting allowance suddenly increases at the end of the turning thread of the tool, so that the cutting force on the tool suddenly increases, which is very easy to cause chipping of the tool tip; and when the setting of the tool retraction direction is unreasonable , it is easy to damage the processed thread; in addition, due to the small diameter of the hole, the iron filings generated during the cutting process cannot be removed from the hole in time, and it is easy to cause the blade to be squeezed by the iron filings; The quality of internal thread CNC ...
