“…However, the selection of steps-over of CL points is arbitrary, as long as steps-over are smaller than 0.75D , where D is the diameter of cutter rotating circle. To simplify calculation and reduce processing costs, Ren [9] employed a direct offsetting technique, but left CC points intervals unconsidered.…”

Because of its high axial rigidity and metal removal rate, plunge milling is employed for pocket walls roughing in aircraft framework manufacturing and dies-and-molds industry. A new method of tool-path planning for plunge milling based on constant scallop height is presented in this paper to determine the proper interval between two adjacent CC (cutter contact) points. The objective is to keep the scallop height constant across the machined surface such that the number of CL (cutter location) points are minimized, while keeping machined surface within given error. The mathematical model is experimentally validated by computer simulation test. Results indicate that isoscallop machining achieves the specified machining accuracy with fewer CL points than existing tool path generation approaches. In a word, the proposed method offers an efficient solution for plunge milling tool path scheduling on pocket walls.

Multi-axis plunge milling has an increasing application in the manufacturing industry to rough machine open blisks. Its objective is to remove mass stock material with high efficiency and machining stability. In multi-axis plunge milling, cutting parameters are usually determined conservatively as constants to prevent excessive cutting forces and unexpected tool breakage. This is an obstacle to improve the cutting efficiency of rough machining. To address this issue, this article proposes an original approach to schedule the feedrate in multi-axis plunge milling of open blisks based on material removal rate. The material removal rate in plunge milling is directly proportional to the area of the cross section on the removed stock material. According to different types of the cross section, one feeding phase in plunge milling of open blisks is divided into three feeding stages. The cross section in each feeding stage is then identified with a mathematic and geometric method. Its area is then calculated by its constituting elements, such as a polygon, circular arches, and elliptical arches. After that, the feedrate is regulated to guarantee a constant material removal rate in the entire feeding phase. Experimental tests are conducted to verify the proposed feedrate scheduling method. This approach can reduce the cutting time and smooth the variances of cutting forces and torque in multi-axis plunge milling of open blisks.

Plunge milling is an effective roughing operation, especially in pockets roughing, because it can efficiently remove a large amount of stock material without high manufac turing costs. However, plunge milling o f complex pockets with islands, whose boundaries could be designed with free-form curves, is quite challenging for multiple plungers have to be used including small plungers to cut necks between islands and their plungers paths are expected to have fewer times of plunging and shorter travel to achieve efficient machining. Unfortunately, little research on this topic was carried out in the past, and the challenge has not been addressed yet. In this research, a new approach is proposed to generate plunger paths for efficient plunge milling of the complex pockets. Its main features include (1) packing plunger circles at a minimum number of locations inside the pocket for fewer times of plunging, (2) placing plunger circles to cover the areas enclosed by the afore-packed circles to clear out the interior pocket material, and (3) planning the shortest paths to connect plunger locations for less traveling time. The advantages of this new approach over the overlapped circles filling (OCfill) and the Catia methods are dem onstrated with two examples, and it can be directly used for pocket plunge milling in industry.
