Abstract
The invention provides a machining method for machining an angle-changeable profile on a common milling machine. A curved surface to be machined is approximately taken as an enveloping surface that is formed by a plurality of double-inclined plane surfaces tangent to the curved surface; angles Theta and Beta of each double-obtained plane surface are two inclination angles of the plane surface to be machined; each angle Beta is measured from a corresponding tangent line on a mathematical model; and each angle Theta, namely a bending edge angle of the mathematical model, can also be obtained through mathematical model measurement; a fixed machine tool spindle inclination angle Alpha is obtained through the angles Beta and Theta; and during a machining process, a machine tool spindle swing angle is fixed by a worker, a part is milled according to a bench worker's mark on the part, and after being milled, the part only needs to be polished slightly by the bench worker before meeting the machining requirement.
Description
Technical field
The present invention relates to the processing method of a kind of plain-milling machine processing varied angle profile, belong to Machining Technology field.
Background technology
Usually when processing parts varied angle profile, the capable mode of cutting of Digit Control Machine Tool can be adopted to process or plain-milling machine segmental machining, but for some processing roughness, dimension precision requirement is not that the varied angle profile of high varied angle face particularly size smaller parts adopts the capable processing mode working (machining) efficiency of cutting of Digit Control Machine Tool not high, and adopt plain-milling machine segmental machining varied angle profile that part surplus can be made large, pincers worker is repaiied the time long, precision is low, roughness is high, production efficiency is low, labour intensity is large, quality instability and the development along with aerospace industry, part complexity is more and more higher, piece surface is more and more designed to curved surface thus causes the problems such as the current machine tool utilization of capacity is not enough.
Summary of the invention
For when processing parts varied angle profile, the capable mode of cutting of Digit Control Machine Tool can be adopted to process or the mode of plain-milling machine segmental machining, but it is current for some processing roughness, dimension precision requirement is not that the varied angle face of high varied angle face particularly size smaller parts adopts the capable processing mode working (machining) efficiency of cutting of Digit Control Machine Tool not high, and adopt plain-milling machine segmental machining varied angle profile that part surplus can be made large, pincers worker is repaiied the time long, precision is low, roughness is high, production efficiency is low, labour intensity is large, quality instability and the development along with aerospace industry, part complexity is more and more higher, piece surface is more and more designed to curved surface thus causes the problems such as current a large amount of machine tool utilization of capacity is not enough, the present invention proposes a kind of by machine tool (vertical) inclined main axes α angle, and disposable clamping is quick, convenient, complete the processing method of the processing of a varied angle profile accurately.
To achieve these goals, the present invention adopts following technical proposals to realize.
A kind of processing method of plain-milling machine processing varied angle profile, it is characterized in that: enveloping surface curved surface to be processed being approximated to multiple oblique plane tangent with it composition, the θ angle of oblique plane, β angle are two inclinations angle of plane to be processed, each β angle all can record by corresponding tangent line digital-to-analogue, the crimp angle of each θ angle and digital-to-analogue also can be obtained by digital-to-analogue measurement, machine tool chief axis constant cant angle α is tried to achieve by β angle and θ angle
，
Machine tool chief axis angle is fixed as the angle calculated, according to scribing by bench worker milled part, finally polishes.
Beneficial effect of the present invention:
1. use processing method of the present invention can realize the varied angle profile that clamped one time just can process smoother, wherein only need pincers worker to polish slightly and just can reach processing request, overcome the part surplus that Digit Control Machine Tool uses the inefficient and machine tool segmental machining of row butt formula processing curve to cause producing large, pincers worker is repaiied the time long, precision is low, and roughness is high, and production efficiency is low, the problems such as labour intensity is large, and quality is unstable.
2. the present invention is easy to operation, the good economy performance of workman.

embodiment 1
To specifically explain the specific process of varied angle profile below.
The first step: technological design personnel record θ, β value try to achieve corresponding α value, part (code name XXX-02-1) as shown in Figure 1, crimp angle θ according to digital-to-analogue
1=0 ° 30 ', θ
2=2 ° 30 ', θ
3=3 ° 30 ' ..., corresponding β value is 5 ° 4 respectively
0', 30 °, 44 ° 30 ' ....Try to achieve respectively:
Through calculating three α values all close to 5 °, thus α value is decided to be 5 °.
Second step: select frock.Be fixed on the workbench of plain-milling machine according to the frock of the shape of part and size and clamping, regioselective coupling.
3rd step: the angle that workman calculates before being fixed as by lathe (vertical) main shaft angle.
4th step: according to scribing by bench worker milled part.
5th step: pincers worker polishing part.
