Processing method of right-angle helicoid

Abstract

The invention provides a processing method of a right-angle helicoidal surface. The processing is carried out through utilizing a single-blade double-curved surface profile-shaped milling cutter. The processing method comprises the steps of during the right-angle helicoidal surface processing process through the single-blade double-curved surface profile-shaped milling cutter, maintaining the axis of the single-blade double-curved surface profile-shaped milling cutter and the axis of the right-angle helicoidal surface to form an alpha-degree angle, and maintaining the distance between the axis of the single-blade double-curved surface profile-shaped milling cutter and the axis of the right-angle helicoidal surface to be b till the processing of the right-angle helicoidal surface is over, wherein alpha is 90 to beta; beta is an include angle between a generating line of the single-blade double-curved surface profile-shaped milling cutter and the axis of the single-blade double-curved surface profile-shaped milling cutter; beta angle is calculated through the formula that beta equals to arctan (2pi*c / h); h is the lead of the right-angle helicoidal surface; c is the minimum distance between the generating line of the single-blade double-curved surface profile-shaped milling cutter and the axis of the single-blade double-curved surface profile-shaped milling cutter; and c equals to b. According to the processing method, the right-angle helicoidal surface with a relatively small error can be processed on a milling machine.

Description

technical field

[0001] The invention relates to the technical field of milling machines, and more specifically, relates to a method for machining a right-angle helicoid by using a milling machine. Background technique

[0002] It is difficult to process large-size and large-lead right-angle helicoids. The difficulty lies in the fact that using a lathe to process large-size and large-lead right-angle helicoids requires a large lathe, while using a milling machine to process large-size and large-lead right-angle helicoids requires The shape error of the processed right-angle helicoid is relatively large. Contents of the invention

[0003] In view of the above problems, the purpose of the present invention is to provide a method for processing right-angled helicoids to solve the problem of large shape errors in machining large-size and large-lead right-angled helicoids on a milling machine.
