Description

This invention relates to a cutting machine and a cutting method. Machining machines that process workpieces to produce, for example, dental molded products, have been known for some time. For example, Patent Document 1 discloses a machining machine comprising a box-shaped case, a front cover, and a machining device housed within the internal space of the case for processing the workpiece. The machining machine described in Patent Document 1 is connected to a dust collector. The dust collector communicates with the internal space of the case and collects cutting debris generated during the machining process. Japanese Patent Publication No. 2017-142617 This is a perspective view of a cutting machine according to the first embodiment.This is a plan view of the workpiece and the adapter.This is a perspective view showing the inside of the processing chamber, with the aperture cover not yet installed.This is a longitudinal cross-section passing through the machining chamber of a cutting machine.This is a block diagram of a cutting machine.This figure shows an example of a cover selection table.This is a perspective view of the aperture cover.This is a longitudinal cross-sectional view showing the diaphragm cover attached to the dust collection port.This is a perspective view showing the inside of the processing chamber, with a diaphragm cover attached to the dust collection port.This is a schematic partially broken perspective view showing the machining chamber of a cutting machine according to the second embodiment.This is a block diagram of a cutting machine according to the second embodiment.This figure shows an example of an aperture selection table.This is a schematic longitudinal cross-sectional view of the machining chamber showing the rotational position of the movable bottom wall. The following describes a cutting machine according to one embodiment, with reference to the drawings. It should be noted that the embodiment described herein is not intended to limit the present invention. Furthermore, the same reference numerals are used for components and parts that perform the same function, and redundant explanations are omitted or simplified as appropriate. [First Embodiment] Figure 1 is a perspective view of a cutting machine 10 according to one embodiment. In the following description, when the cutting machine 10 is viewed from the front, the direction away from the cutting machine 10 is considered the front, and the direction towards the cutting machine 10 is considered the rear. Left, right, up, and down refer to the left, right, up, and down of the cutting machine 10 when viewed from the front, respectively. Also, the symbols F, Rr, L, R, U, and D in the drawing refer to the front, rear, left, right, up, and down, respectively. The cutting machine 10 according to this embodiment is a cutting machine that cuts a disc-shaped workpiece held in an adapter. Figure 2 is a plan view of the workpiece 1 and the adapter 5. The cutting machine 10, in this case, is a device that cuts the workpiece 1 to produce dental molded products, such as crowns, bridges, copings, inlays, onlays, veneers, custom abutments, and other dental prostheses, as well as artificial teeth, denture bases, etc. The cutting machine 10 according to this embodiment is a dry-type cutting machine that does not use coolant. The workpiece 1 is composed of, for example, resins such as ABS, PMMA (polymethyl methacrylate resin), and dental resin, or wax, zirconia, gypsum, etc. The material of the workpiece 1 may also be composed of other materials, such as resins such as PEEK, glass fiber reinforced resin, and hybrid resin, ceramic materials such as glass ceramics, or metallic materials such as cobalt-chromium sintered metal. The material of the workpiece 1 is not particularly limited. The shape of the workpiece 1 is disc-shaped (circular). However, the workpiece 1 may also have other shapes, such as block-shaped (e.g., cubic or rectangular). The adapter 5 holds the disc-shaped workpiece 1. In this case, the adapter 5 is a flat plate-shaped adapter with a roughly circular insertion hole 5a formed in the center, corresponding to the workpiece 1. The workpiece 1 is held by the adapter 5 by being inserted into the insertion hole 5a. The workpiece 1, while held by the adapter 5, is then placed in the cutting machine 10 and processed. As shown in Figure 1, the cutting machine 10 has a box-shaped housing 20. An opening is provided on the front side of the housing 20, connecting the internal space of the housing 20 to the outside. A processing chamber door 25 and a storage chamber door 26 are provided in the opening, allowing them to be opened and closed. Behind the processing chamber door 25 and behind the storage chamber door 26 are a processing chamber 21 and a storage chamber 22, respectively. The processing chamber 21 is the area where the workpiece 1 is cut. The storage chamber 22 is the area where multiple adapters 5, each with a workpiece 1 att
