Description

  The present invention relates to a method and system for performing vibration finishing of composite laminate parts.

  In various manufacturing processes, it is desirable to deburr a manufactured part after machining or other processing steps. Burr and surface roughness are often found in parts manufactured by casting, machining, lamination, and other manufacturing techniques, making them unsuitable as finished products. Finishing such parts may include deburring and surface finish modifications. Deburring is a process for providing a part having desired finishing characteristics, and is a general term for various processes for rounding or smoothing an edge of a part and deburring the edge. .

  Conventional deburring of manufactured parts has a very large proportion of manual work, and deburring is performed using a grinding machine or other tools for smoothing the edges and surfaces of the parts. Recently, development of a vibration-type deburring process for deburring a mass-produced part and smoothing the surface has been progressing. In these processes, the part to be finished is typically placed in a vibratory finishing device, such as a vibratory tank or saddle vessel, along with particles of a finishing medium such as an abrasive material. As the finishing medium is stirred in the bath, the particles of the finishing medium repeatedly contact the edges and surface of the part to be finished. The finishing media may include, for example, particles having relatively pointed tips or corners that enter a groove or gap in the part to remove burrs and sharp edges and smooth the part. In some cases, the finishing medium may have a cleaning effect or a surface polishing effect. In many cases, when the vibration-type deburring process is performed, the surface is slightly sanded.

  By vibration-type deburring of manufactured parts, the manual labor required for deburring can be reduced and more uniform results can be obtained. However, this method is mainly applied to metal parts, and it is considered that it has not been applied to composite laminated parts for various reasons. Accordingly, in general, deburring of advanced composite laminated parts that have been processed or assembled is still performed using manual deburring tools and methods. Unfortunately, these manual processes tend to be labor intensive and can result in variations. In this case, excessive deburring is performed on some parts, which may provide parts that do not meet specifications regarding edge dropping and surface finishing.

  The present disclosure is directed to one or more of the problems discussed above.

  In one aspect thereof, the present disclosure provides a method for performing vibration finishing of a composite laminate component. In the above method, the particles of the vibration medium containing the titanium oxide abrasive held by the synthetic binder are placed in the tank of the vibration finishing machine, and the composite laminated component is placed in the tank so as to be substantially embedded in the vibration medium. Disposing and operating the vibration finishing machine at a vibration frequency of 40 Hz to 50 Hz with the vibration medium and the composite laminated component disposed in the tank.

  In another aspect, the present disclosure provides a method for deburring a composite laminate component. In the above method, the particles of the vibration medium including the titanium oxide abrasive held by the synthetic acrylic binder are disposed in the tank of the vibration finishing machine, and the composite laminated component is substantially embedded in the particles of the vibration medium. Disposing in the bath, supplying about 0.35-0.50 gallons of wash water per cubic foot of finishing media to the vibrating media, and placing the vibrating media and composite laminate parts in the bath. And operating the vibration finishing machine for 45 to 60 minutes at a vibration frequency of 40 Hz to 50 Hz via a rotating shaft performing eccentric rotation of about 10%.

  In yet another aspect, the present disclosure provides a system for finishing a composite laminate part, the system comprising a vibration finishing machine having a tank of a capacity suitable for containing the composite laminate part, and a system disposed in the tank. A set of vibration medium particles formed and a water supply port. The tank is configured to vibrate at a frequency of 40 Hz to 50 Hz. The vibration medium particles are a titanium oxide abrasive held by a synthetic binder. The water supply port is configured to supply process water to the tank while the vibration finishing machine vibrates with the composite laminated component substantially buried in the vibration medium particles. Deburring takes place substantially in contact with the particles.

It is a perspective view of a saddle type or tank type vibration finishing machine. It is sectional drawing of the tank of a vibration finishing machine which shows a drive shaft and an offset counterweight. It is a close-up view of a tank-type vibration finishing machine in which a finishing medium is charged and a part is finished inside. FIG. 6 is a perspective view of various sized media particles that can be used in a deburring process according to the present disclosure. It is a fragmentary sectional view showing a composite material from which an edge was dropped by vibration type deburring processing concerning this indication. It is a logic flowchart which shows the outline | summary of each step in the embodiment about the deburring process of the composite laminated component which concerns on this indication.

  While the disclosure is susceptible to various modifications and alternative forms, specific embodiments are shown by way of example in the drawings and will herein be described in detail. However, the present disclosure is not intended to be limited to the particular forms disclosed. Rather, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.

  As mentioned above, bulk finishing, or “vibration finishing” refers to a mechanical and / or chemical treatment applied to finish a component. The vibration finishing process can remove burrs from mass-produced parts and smooth the surface. Vibration deburring can reduce the burden of manual work, and can obtain more uniform results than manual deburring, but it is a method that is mainly applied only to metal parts. is there. For example, manufacturers of vibration finishing equipment have the recognition that metal parts are the main area of application of this technology and that mass finishing techniques are also used in wood, rubber, stone and plastic. ing. In particular, it is believed that vibration finishing has never been applied to composite laminated parts. One reason is that typical vibration finishing media are not compatible with composite materials. Another reason is that composite laminate parts tend to “float” on vibrating media and do not naturally enter these media. Furthermore, commercially available vibration finishing machines operate only at fixed frequencies and amplitudes that are not suitable for finishing composite laminate parts. Thus, known vibration finishing systems and methods are not only obstructive when applied to finishing composite laminates, but also prevent the system from being adjustable to be suitable for finishing composite laminates. There are factors.

  Advantageously, the systems and methods disclosed herein have been developed to apply a vibratory deburring process to composite laminate parts. The automatic vibration deburring machine used in this process uses a specific deburring medium, a specific number of revolutions (RPM) and a processing time to deburr these parts. There is no need to manually deburr each time. This saves time and costs and eliminates many ergonomic problems associated with manual deburring. Pre-tests conducted with several media have yielded good results that meet stringent specification requirements.

  FIGS. 1 and 2 show a tank-type vibratory finishing machine 100 commercially available from Rosler and other manufacturers in Battle Creek, Michigan, USA. Another commercially available vibration finishing machine used for this type of processing is the Model SVP-5 manufactured by Hammond Roto-Finish in Kalamazoo, Michigan. Vibrating finishing machine 100 includes a large basket or tub 102 containing a finishing medium, indicated generally at 104, and a part 106 to be processed. The tank 102 is supported by a spring 108 and attached to the motor 100. This motor drives a drive shaft 112 located below the tank 102. The drive shaft 112 is attached to a tank 102 fixed to a spring together with a bearing 114, and includes an eccentric counterweight 116. Thereby, the drive shaft 112 vibrates when the drive shaft rotates, and this vibration is transmitted to the tank 102 via the bearing 114. With this configuration, the tank 102 is sized according to the frequency according to the rotational speed of the drive shaft 112 and the weight of the counterweight 116 and the offset position (that is, how far the counterweight is off-center). Vibrate.

  As shown in FIG. 2, the tank 102 vibrates while drawing a substantially ellipse as indicated by an arrow 118 by the rotation and vibration of the drive shaft 112. Due to the vibration of the tank 102, the individual particles (the reference numeral 136 shown in FIGS. 4A and 4B) of the finishing medium 104 and the part 106 to be finished are drawn in a small circle as indicated by an arrow 120. Rotating individually within 102, the entire medium 104 rotates or stirs to simultaneously “roll” around the horizontal axis in one direction as indicated by arrow 122.

  Traditionally, the typical vibration finishing machine shown in FIGS. 1 and 2 typically operated at a fixed vibration speed. In fact, in this type of vibratory finishing machine, adjustable speed of operation seems not available in the market, and all available on the market operates at a speed of 2100 RPM. Unfortunately, this type of vibratory finishing machine operating at the above speeds is not very effective for composite materials for the reasons described above.

  Advantageously, the vibration finishing system described herein is compatible with composite materials, and the operating parameters of the system, specifically the vibration frequency and amplitude, are developed for these composite materials. Optimized. In one embodiment, vibration finishing machine 100 includes both a motor RPM controller 124 and a tachometer 126. Thereby, the user adjusts and confirms the RPM of the motor 110, and as a result, the vibration frequency is determined. This speed adjustment mechanism allows the user to find the optimum RPM for the part 106 to be finished by changing the RPM regardless of whether it is a composite part or a part of any other type. This allows the user to find the appropriate speed to finish the composite material and, if necessary, use a single vibratory finishing machine, metal parts, composite parts, and other types of parts Can be selectively adjusted for.

  In one embodiment, using a motor frequency of about 2700 RPM with an offset counterweight 116 disposed on the drive shaft 112 may cause the vessel to vibrate at a frequency in the range of 40-50 Hz, for example, specifically 45 Hz. I know. A frequency in this range is effective for composite materials, but it has been found to be ineffective for composite materials at 35 Hz, a typical frequency in conventional vibration finishing machines.

  As shown in FIGS. 1 and 2, the vibration finishing machine 100 can be configured so that the number of counterweights 116 can be increased or decreased. With this configuration, the user can set a desired offset so as to have a desired amplitude (when combined with the selected RPM). As will be apparent to those skilled in the art, the vibration frequency is a function of the rotational speed of the drive shaft 112 and the amplitude is the mass of the counterweight 116 relative to the total mass of the vessel 102, the vibration medium 104, and the component (s) 106. Is a function of Of the features described above, the latter is affected by the size and capacity of the tank 102. In one test embodiment, a Hammond SVP-5 vibratory finishing machine was modified in accordance with the present disclosure and used to finish composite parts. The modified machine included a tank having a capacity of 5 cubic feet and was modified to operate at 2700 RPM as described above. This machine included four 4.5 lb counterweights 116. Each of these weights was increased by 1.5 pounds, and as shown in FIG. 2, four 6 pound counterweights (24 pounds in total) arranged eccentrically with respect to the drive shaft were arranged. The addition of a weight to the weight mechanism helped provide the amplitude required for deburring operations using a lighter deburring medium.

  Using the modified counterweight system as described, when the rotational speed of the drive shaft is 2700 RPM, the drive shaft rotates about 10% eccentrically (relative to the diameter of the shaft), as shown by the dashed circle in FIG. I found out that For example, a 3 inch diameter drive shaft 112 with a suitable counterweight 116 is arranged to perform an eccentric rotational motion of about 3.3 inches (ie, 10% greater than the shaft diameter) when rotating. This amplitude causes about 0.001 inch of vibration in individual abrasive media particles 136 at a frequency of 40-50 Hz. This amplitude is considered applicable to all size parts and all size vibration finishing machines. Thus, it is clear that as the size, volume, and mass of the vibration finishing machine 100 increases or decreases, increasing or decreasing the mass of the counterweight 116 provides the desired amplitude at the same vibration frequency.

  FIG. 3 is a close-up view of the tank 102 in which the finishing medium 104 is loaded and the part 106 is finished inside. The finishing medium 104 is stirred in the tank 102 by the vibration operation of the tank 102 and moves as if it were a liquid. The part 106 buried in the finishing medium 104 rolls around gradually in the medium, while the particles of the finishing medium repeatedly come into contact with the edges and surface of the part and gradually deburr, thereby causing rough edges and Smooth the surface and round the edges of the part.

  Vibrating finishing machine 100 includes one or more water inlets 128 for flowing process water through the polishing media 104. Process water is slowly and regularly supplied to the medium 104 in small amounts with mild soap (eg, 30: 1 water to soap ratio). As a result, fluidity, lubricity, and cleaning action for washing away media scraps and wear particles from parts can be obtained. As shown in FIG. 2, the tank 102 includes an outlet or a drain port 130 at a lower end thereof, and further includes a drain pipe 132 for discharging process water. By installing a strainer, a filter, or the like (not shown) in the drain pipe 132 or in association with the drain pipe, it is also possible to remove particles from the medium shavings and parts washed away by the process water. The machine 100 may be configured to discard these particles in a disposal tank (not shown) before discharging the waste water. The system for supplying process water and the associated waste tank may be standard parts normally included in commercial vibratory finishing systems.

  As shown in FIG. 3, by providing a partition 134 in a single tank 102, a plurality of parts 106 may be finished at the same time in each partitioned part of the tank 102. The divider 134 is also shown in the tank 102 of the finishing machine 100 in FIG. Depending on the size, shape of the parts, and whether and how many parts 106 can withstand accidental contact with each other during the finishing process, A single or non-divided portion / region may be simultaneously charged and finished together.

  As described above, the finishing medium 104 includes individual abrasive particles 136. 4A and 4B are perspective views of individual finish media particles 136 that can be used in a deburring process in accordance with the present disclosure. The finishing media 104 can include particles 136 of various shapes and sizes. For example, the particle 136a illustrated in FIG. 4A has a tetrahedral shape, and the particle 136b illustrated in FIG. 4B has a conical shape. Other shapes can also be used. These particles 136 vary in size, with the largest dimension being in the range of about 0.25 inches to about 2.5 inches. Other sizes can also be used. As shown in FIGS. 4A and 4B, the particles 136 may have relatively pointed tips or corners 138 that enter the grooves and gaps of the part 106 to be finished so that they are on the outer surface of the part. Remove burrs and sharp edges to smooth parts.

  The particles 136 of the finishing medium 104 are composed of two elements: an abrasive and a binder. In one embodiment, the abrasive comprises titanium oxide and the binder is synthetic acrylic. In a more specific embodiment, the medium is about 10% to 20% titanium oxide, and the titanium oxide occupies 80% to 90% of the volume of the particles 104, a synthetic urea-resin. It is held by the binding material. Vibrating finishing media having this general composition are commercially available, for example, under the product name SY from Vibra-Finish in Los Angeles, California.

  With respect to vibration finishing of composite parts, as disclosed herein, the specific gravity of the finishing medium is in the range of about 1.5 to 2.0, and the cross-sectional density of the total volume of particles 136 is the object to be finished. It is considered desirable to be approximately equal to the cross-sectional density of the composite laminated component 106. Such an aspect of the vibration finishing medium 104 allows the composite part 106 to “sink” naturally in the medium without “floating” on the medium, and thus substantially embedded in the medium.

  The composition of this medium is different from standard media commonly used for finishing metals and other parts. Specifically, many vibration finishing media compositions use aluminum oxide as an abrasive, but this material is generally incompatible with composite materials. On the other hand, it was found that the titanium oxide abrasive had good compatibility with the composite part. However, it is believed that the suitability of this type of abrasive media for composite materials was not previously known. Furthermore, since the binder is a synthetic material, no finishing compound (eg, soap) is required in the finishing process. Instead, normal water can be used as process water, so that no soap can be used for the parts, only the wash water can be received and towel dried to complete the process.

  The abrasive particles 136 of the medium 104 have generally constant properties throughout, and as each particle 136 gradually wears with use, the shape and size of its surface will change, but the abrasive properties will remain unchanged. Is done. That is, during use, the surface of the abrasive particles 136 gradually wears to expose the underlying material, which also has substantially the same polishing quality and characteristics. As described above, the abrasive particles 136 maintain their usage characteristics, even if they gradually wear out during use, until the point at which replacement with new full size particles is deemed desirable. Effective replacement of the worn particles 136 can be accomplished by periodically adding new particles 136 to keep the larger full size particles at a constant rate.

  When the vibration-type deburring process is performed using this finishing medium, the surface of the composite material is slightly sanded. Another aspect of vibratory deburring of parts using the apparatus and methods disclosed herein is to perform edge drop or edge removal on parts. It is well known in the manufacturing industry that sharp edges in machine parts are often undesirable, but are necessarily a byproduct derived from various manufacturing and / or processing steps. FIG. 5 is a partial cross-sectional view showing the end portion 202 of the composite component 200. Prior to deburring, the end 202 of the component 200 includes an angular edge 204. After vibration finishing in accordance with the present disclosure, the angular edge 204 is scraped to become smooth and a rounded surface 206. The desired degree of edge drop or edge removal varies from case to case. Using the present system and method, an exposed edge of a composite part can be edge dropped or rounded by about 0.005 inches. Obviously, the magnitude of the edge drop depends at least in part on the length of the vibration treatment and the coarse particle level of the polishing media 104.

  FIG. 6 is a logic flow diagram that outlines the steps in an embodiment of a method 500 for deburring and finishing a composite laminate part according to the present disclosure. First, finishing medium particles are put into a tank of a vibration machine (step 502). It is considered desirable for the tank to be filled with about 50% to about 80% of the capacity. Next, supply of process water is started (step 504). The process water may be ordinary water that does not contain additives such as soap. Process water improves the finishing process by flushing swarf away from the collection of finishing media particles and removing residues from wear of parts and polishing swarf from finishing media particles. . The flow rate of process water used for this treatment is approximately twice the amount of water normally used for vibration finishing of metal parts. Generally, it is believed that process water at a flow rate of 0.35-0.50 gallons per hour per cubic foot of finishing media volume is used. In one embodiment, process water at a flow rate of 2 gallons per hour is used with a 5 cubic foot tank.

  After starting the process water flow, the machine can be started (step 506), that is, the vibration starts at the desired frequency. Next, when parts to be deburred are put into the tank of the finishing machine (step 508), these parts are buried in the finishing medium. In order to avoid breakage due to contact between parts and / or to avoid a situation where parts are not sufficiently finished, the total volume of the parts put into the tank exceeds about 10% of the total volume of the tank. It turns out that not desirable. Next, the part is left in the vibrating tank for a set time (step 510), and processing is performed during that time. In one embodiment, processing a part for about 60 minutes has been found to give good results. Usually, it is believed that a vibration finish of about 45-60 minutes will be sufficient. One skilled in the art will be able to determine the optimal settings for any part and media combination to achieve the desired edge removal and surface treatment.

  When the necessary processing is completed, the finished part is taken out from the machine (step 512). Preferably, the batch process flow can be performed more quickly if the parts are removed from the vessel while the machine is still running. Alternatively, the machine and process water supply can be stopped before or after the part removal operation (step 514). After the processing is completed, the parts are washed with fresh water (step 516) and dried to make these parts usable. Composite laminated parts are generally slightly glossy and appear to have been sanded, especially the “tool side” of the part (ie, during the curing process, the “form” or “tool” In the composite part on the side pressed against “)”, it appears prominently. When the deburring is not performed on the composite part tool side, the part is glossy as compared with the part subjected to the processing disclosed in the present specification. After processing a part or a part of the quantity as described above, add the part to the tank and repeat the process (step 508), or if necessary, any one of the above steps. Return to one.

  As mentioned above, the finish media particles 136 will gradually wear with use. Therefore, in order to keep the particle size distribution within a desired range, the particles that are below the predetermined lower limit size are removed, and new particles corresponding to the removed particles are added, so that the vibration medium is periodically removed. It is desirable to replenish (step 518). This can be achieved by transferring all the particles from the tank to a vibrating sieve mechanism (not shown). The vibrating sieve mechanism sorts out all the particles of a predetermined size or less according to the size of the sieve used. , Remove small particles. Since the remaining particles are larger in size than the used sieve, they can be returned to the tank and used continuously. In addition, by introducing a collection of new particles (or appropriately sized particles) into the vessel, the amount of particles returns to the desired “full” level (step 502). In one embodiment, the replenishment of the vibrating media particles removes particles that are less than about 0.5 inches in size and throws particles that are 1 inch to 2.5 inches in size in an amount that corresponds to the removed particles. including.

  The processing disclosed herein combines specially developed machine operating parameters and processing times with specific and specific vibration finishing media compositions and by applying this special deburring media to a composite substrate. realizable. Conventionally, it is considered that such processing has not been attempted until now in the composite material industry. This is because the technical understanding of how to use the polishing medium for the composite substrate has not been deepened.

  The apparatus and method of the present disclosure allows for automatic batch processing of composite parts and can remove burrs on the outer surfaces of these parts. By using automatic finishing, batch processing of many parts becomes possible, and excessive deburring due to human error can be eliminated. Furthermore, the possibility of ergonomic problems often associated with manual deburring, such as carpal tunnel syndrome, can be eliminated. The process disclosed herein can perform deburring of manufactured composite parts and many composite parts including composite parts to be manufactured in a much more cost-effective and safe manner. Therefore, enormous time and cost can be saved. Labor-intensive manual deburring using automated equipment can greatly reduce labor costs.
