Asset Maintenance Management For Bridgeport Interact 412 Milling Machine

Safety Procedures

Discuss about the Asset Maintenance Management.

Most of the milling machines are very versatile as a result of the fact that majority are used while on a flat surface. Therefore, the users should apply a diversified mechanism of ensuring that they are well maintained so as to uphold their ability to perform numerous activities. This document applies to all students, staff and the faculty of engineering and also other people who wish to use Bridgeport Interact 412 Milling Machine. Figure 1.1 shows the vertical image of a Bridgeport Interact 412 Milling Machine.

Figure 1.1

It is made up of on and off switch whose primary function is putting on and off the machine. However, its usage can also be applied in changing the direction of the spindle. It is also fitted with brakes whose work is stopping rotating rod immediately after turning off the machine. Another component is the quill knob whose function is locking quill at its prescribed height. Additionally, it has a power drawbar used for removing or inserting of the collet from the spindle of the machine. Besides, it has a vice which is used for clamping pieces of work onto the milling machine table. Apart from the functional parts, it has x-axis alarms used in indicating for course of work being performed by the milling machine. Such indicators change color depending on the message in which it entails to pass to the operator (Boglietti et al., 2016). The parts named and their functions synchronized together forms the basis through which this type of milling machine works. This device is made in such a way that immediately the on and off switch is directed on the course of action; it ignites the entire system to run or stop as long as everything else is in place. During work, one should ensure that all the guards exist to avoid the accidents since working using this device is fatal. It has to be operated by one person at ago so as to prevent confusion since this may lead to perils if not well planned and it should perform a small task at ago.

In any working environment, one should ensure that security is paramount. Working using Bridgeport Interact 412 Milling Machine is quite hazardous in that it has some sharp cutters which can cause massive damage to the user. Moreover, this machine has numerous moving components, and the majority of them are in a metallic state. Therefore, it is incumbent to outline that one should be very carefully working and walking around to minimize damages (Vélez-Reyes, Verghese & Fliess, 2016). More so, Metals being grounded can cause eye injury since some may release some small form of metals which may lead to partial or even permanent loss of eyesight. The chemical used in cleaning and removing of corrosions from metals can irritate the skin, and thus one should wear protective clothes at the workplace to counter this menace. The hair and the clothes should be held tight so as to avoid conduct with the metals and the reagents used since this can be fatal (Blasen & Lane, 2016). A lot of emphases should be put on personal safety since this is the primary level of care in the industry. One should always wear protective classes so as to avoid coming into conduct with uncertainties in the premise. Additionally, the required footwear must be worn at all the time to prevent piercing from objects. Likewise, one should avoid wearing of rings and the jeweler since they can easily lead to problems since they are metallic hence good conductors of heat. Furthermore, long hair and loose clothes should be avoided (O’neal, Meiss, & Caterpillar, 2016). Raw material and wastes product is another area in which the traders should factor while using milling machines. Since the majority of the milling companies deal with metals, it is important for them to collect waste products from residential resulting from tear and wear of households such has cups and plates. They can use to make other valuable material by melting them and thus minimizing of the environmental degradation. This raw material should be handled with care by people with technical know-how since they are quite dangerous. The equipment should be lubricated from now and then so as to ensure smooth flow of work at the same time ensuring that the prevention of tools from rust. Grease and oil should be applied from time so as to achieve longevity of the system.

Identification of Critical Machine Parameters

Parameters to be implemented in this form of milling machine has to work hand in hand with the intended subject matter of coming up with quality output. Therefore, the considerations factored have all the ingredients for an exceptional result. The machine should be fitted with precision KURT model 675. It has been established that this type is easy to set apart and thus one can constantly check what is taking place during grinding (Ahmad & Plapper, 2015). Moreover, it is made up of chips which do not fall on top or underneath the parallels easily. Consequently, its management becomes a symbol task in that one cannot concentrate too much on checking for their functionality from time to time. The parts produced as a result of the working standard of this machine are thus perfected leading to accuracy and quality output. Additionally, the squaring stock and face milling of Bridgeport Interact 412 Milling Machine should be created a way that its base is flat (Rasouli & Lagoa, 2017). This property is crucial since it enables one to produce the parts which are standard in both quality and shape. They usually work for end mills up to 750mm in diameter. Besides, this parameter enables one to grind any material in different forms, and thus cases of having to buy a different milling machine whenever one wants to make several shapes are eradicated. In a nutshell, it is viewed has very economical and quality and thus one has to observe this feature before making purchases entailing milling machines. Apart from that, an excellent milling machine has to apply the usage of clean cutting fluids. Different fluids are designed to provide the correct amount of lubricity, increased tool lifespan, cooling and better surface finish. To obtain the prescribed qualities, one has to ensure that all fluids are thoroughly washed, and when removing the machine from the lubricant, it must be dry so as to prevent corrosion (Mannodi-Kanakkithodi, Pilania & Ramprasad, 2016). For instance, A9 cutting fluids are used in the cleaning of the aluminum and other soft metals so as to reduce the chances of making them rough. Likewise, accurate cutting should be employed in Bridgeport Interact 412 Milling Machine. It is prudent to underscore that collet or drill chuck should be utilized in milling tools since they are sharp and they do not leave marks on the products. R8 mill collet can hold end mills, fly cutters, boring hearing, shell mills and the counter bores giving them added the advantage of being a major constituent of Bridgeport Interact 412 Milling Machine since it improves its efficiency (Zhang et al. 2016). What’s more, a device should be equipped with a long lasting Digital Read Out (DROs) since they play an integral part for accuracy positioning. It is made up of X and Y axis both having an accuracy index of 0.0001. The closeness to zero range is to enhance the quality of the metals produced during the milling work.

Maintenance Producers

Like any other machine, Bridgeport Interact 412 Milling Machine requires a routine maintenance to upload a sound output and also a have the capability to last for long duration. Moreover, the support applied helps the company or the owner in reducing costs incurred during the breakdown. Primarily, Bridgeport Interact 412 Milling Machine should be isolated from the electric gadgets before the technician carries out the maintenance function (Doi, Uhlmann & Marinescu, 2015). The reason is that most of the metals are good conductors of heat and thus in case one carries on with the work before switching or disconnecting the machine from the electricity, one might be electrocuted. Secondly, Rodríguez et al., (2017) states that, the backlash adjustment should take place. The Endeavour should be done by a specialist since it is quite technical for someone without the knowledge of machines. In this stage, one should crack the fable to the left withdrawing of screw ‘A’ ½ a turn. This technique will ensure that the machine opens smoothly preventing any undue breakage of other parts of the component (Soori, Arezoo & Habibi, 2016). After that, one should tighten screw ‘B’ so as to hold the entire system well in place and avoid collapsing of other parts which are intact. After that, one should lock screw ‘A’ to ‘B’ to avoid losing of the bolts. It should be done weekly.

The second procedure is the replacement of Vee and Timing Belt. This area is achieved by isolating of the machine and removing of the belt guards, motor and the drawbar followed by lowering of the quill and removal of the six screw type ‘A’ (Özceylan, Kabak & Da?deviren, 2016). The belts may or not be changed depending on their condition. After that, one refits the belt guards and closes the machine. It should be done weekly by an expert. The third procedure entails brake shoe replacement. One should begin by removing of two screws ‘A’ and two screws ‘B’ and pushing of the bearing hub to twist ‘C’ for efficiency purposes during the task. Afterwards, one should remove three screws from ‘D’ and replace the brake shoe to ensure friction of the device is maintained accordingly (Tai et al., 2014). Finally lock pin ‘D’ tightly by using of washers and the nuts. This step should be carried by a technician after every one month thus should be planned accordingly.   

Fourthly, a technician should balance spring replacement in the device. One can achieve this by applying a lock on the quill at the top to counter movement. It is followed by the removal of key ‘C’, hub ‘B’ and screws ‘A’ and ‘D’ which will provide room for free housing rotation thus releasing spring tension. Housing ‘B’ should be rotated anti-clockwise from the head casting position and refitting of the spring to the main house. This part is quite time-consuming and technical thus services of a machine operator should be employed. It has to be planned after every two months (Ostadi & Saifpanahi, 2017). The fifth procedure entails feet trip adjustment which involves releasing of the lock nut ‘A’ and engaging of trip handle ‘C’. The nuts should be on the top of the quill and adjusting of screw ‘D’ until ‘C’ trips. This routine should be done anytime by the operator thus predictive task. The sixth step entails collecting of the aligning screws. It is done by removing of screws ‘A’, ‘C’ and collecting alignment ‘D’. Later on, one should replace these bolts with a set of new ones. One should avoid over tightening since it can lead to breakage. It can be done monthly by the milling operator and should not be planned as such.

Quill removal is the seventh procedure and entails isolation of the machine, removal of belt guards, motor, drawbar, fully extended quill, three nuts ‘A’, one screw ‘B’ from the top of the quill, dock spring housing ‘C’ and refitting of the belt guards. After that, one should clean the entire system and reassemble it before checking if the machine works properly. This operation should be planned and done by a professional after every six months (Pavlovic & Fragassa, 2016). The final course of action is the changing of the gear case oil by draining and refilling it after the first two months of operations and after that twice yearly. The plugs have to be replaced with proper oils so as to ensure its flow is well. It should be a planned task and has to be done by a mechanic.

One of the major problems which occur during the operations Bridgeport Interact 412 Milling Machine is the Positioning accuracy. It occurs has a result of the failure in the integration of the x and y axis by having an accuracy level between 0.0003 and 0.0005 causing the output produced to have a significant large deficiency index. It usually occurs at the Digital Read Out (DROs). This problem can be solved by making x and y-axis to have an accuracy level of 0.0001 for the two axis. Therefore, troubleshooting this stress is a must since for any output realized to be quality it must have an accuracy index of 0.0001. It is achieved by the fitting of the equipment with an electronic display which is easily monitored and can detect problems as soon as it occurs because they are computerized. 

Besides, improper tools are also one of the faults experienced in running of the milling machine. The operator observes burn marks on the edges of the material. It can be deduced from the point of view that it resulted from a blunt object or a cutting lube. The output could be seen with raised marks and rough edges. It takes place in the feed speeds. Novak et al. (2017) reiterates that, increasing feed speed can solve this problem through applying of the lubrications on them. This will lead to an increased speed at which the machine operates and thus reducing the productivity of the milling system. Moreover, the parts can be sharpened since it takes time for a blunt object to complete a task and by the date of completing it, a lot of unsightly marks are left on the edges of the materials. Besides, improper programming has also been indicated as one of the major faults in the milling machine. This issue in most cases arises when new employees are left on their own to perform the tasks (Hamzadayi & Yildiz, 2016). The matter arises because most of them are not aware of the cutting errors involved. It occurs in the face milling and the squaring stock of the machine.

The menace can be solved by ensuring that the new employees are knowledgeable on the matters to do with the proper setting of the squaring stock and the face milling parameters. Moreover, the calibration data, offset information captured by the DROs is correct, and compensation data within the milling machine is in line with the functionalism of the Bridgeport Interact 412 Milling Machine. The drive belt multifunction is also another fault experienced by the owners of the Bridgeport Interact 412 Milling Machine. It is detected by the slow moving of different components making up of the grinding machine. The matter can result from reduced output received since the material obtained of various shapes from the usual ones. It normally takes place in drive belt area. It is important for the operator to change the belt since it might be worn out. Besides, one can also check on the screws because they might be loose or too tight thus inhibiting the functionalism of the machine.
