Improve processing plant settings to speed up assembly

In order to remain competitive in the market, K & L Microwave Inc. must assemble more than 200 machine tools as soon as possible within a normal work week. The company produces RF devices and microwave filters for military, wireless communications, and satellite communications systems. Its domestic customers do not negotiate delivery times and they need to obtain them when they need it. Otherwise, they go elsewhere to buy them. . In order to shorten the installation time and expedite the overall completion time, K & L Microwave Company does its best. Standardized equipment and procedures. Therefore, the factory can assemble a machine (sometimes 3 minutes) within 5 minutes and complete all work within 5 days and sometimes within 1 day. It took up to 8 minutes to build a machine in the past and the average time to complete all work was 10 days. At K & L Microwave, standardization starts with machine tools. When a factory installs a row of machine tools, they are all the same brand of machines. For example, the factory operates a row of six horizontal machining centers, all manufactured by the same manufacturer (Kitamura Machinery, USA). According to Joe Searing, supply chain manager for K & L Microwave, the standardized machine tool standardizes workpiece assembly not only from the machining point of view but also from the programming. He added: "Because we can write a program that can be used on any machine in the production line, so that we can quickly switch from one task to another. When dealing with processing tasks, we must always pay attention to speed and flexibility. Because K&L is designing and producing products according to the order.” When there are processing tasks, programmers program it and then directly deliver it to a horizontal machining center on the production line. The factory staff can assemble as soon as possible according to the specific process. Components. For example, programmers work from a list of tool standards, and machine users start working from a standard/fixed machine offset setting, which helps them determine which task is best on which machine. If the machine tool is being processed, they can easily switch tasks to another machine on the production line. Searing said: “This is very difficult for a plant that is running several machine tools from different manufacturers.” Since mechanical workers start working from standardized machine offset settings, they do not waste time from the start of the mission. Come to explore or find the edge of the part's position. For all workholdings, no matter what parts are machined, each machine is referenced to the same offset. Therefore, all parts on each machine tray are adjusted according to the machine - it knows where they are - effortlessly. K&L Microwave's machine programmers write an average of 30 programs per day. In addition to working on a standard list of tools, they also use what the factory calls a "gold standard" program to help speed up work. These programs are proven and validated procedures that the machine operator is familiar with and can operate immediately. In the past, when performing a repetitive task, the factory had to re-verify the program and wasted time. Thanks to the programmers for their contributions, Searing said that the factory had not encountered a machine failure due to a program error. The standard tool list is particularly suitable for the K&L Microwave's Kitamura machining center, including its machining center that houses only 40 tools in its tool magazine. In addition to the tool list, the factory also uses a "tool cart" device next to each machine. In essence, tool carts double the number of tools in a machine tool by accommodating the tools needed for a certain task. Most machine tool magazines contain tools that are standard for all tasks. At the same time, the factory also retains tools that change as the task changes. These tools come from the tool cart.
Tool "tag" system
Each machining center can process up to 8 different workpieces at the same time using a tool cart. Mechanical workers can always know what tool is placed in what magazine. They do not need to waste time around the machine to see where the tools are. If the mechanic needs to change the tool in the tool magazine or on the tool cart, he can use the factory's "tag" system. Each tool, whether in the tool magazine or on the tool cart, has a corresponding numbered label, listing its type and length. When the tool changes, for example, from the tool cart to the magazine, the mechanic puts its corresponding label in the appropriate empty space on the "label" board. The labeling plate is located on each machine, leaving empty space for each magazine number and each tool cart number. Ed Conklin, manager of continuous improvement at K & L Microwave's processing plant, said: "We have standardized all non-standard tools." There may be about 10 tools that vary between tasks, so usually on each machine, Many magazine pockets are open. These "normally-open" tool bags, tool carts, and labeling systems eliminate the need for people to guess which type of tool is needed in the task, track where the tool is between tasks, and by having the factory prepare the tools needed for the job in advance. Reduce assembly time. Standardised machine tools, tools and workholdings also provide flexibility for handling priority tasks, making work arrangements no longer a problem at K&L Microwave, because standardization allows any mechanical worker in the factory to Operate any task on any machine on the production line. Some mechanical workers assigned the designated machine tools. The factory calls these machine tools their "bases." However, if necessary, a mechanical worker can cohesively switch from one machine tool to another, without delaying production. In fact, Searing said that the factory's mechanical workers are proud of their ability to operate different machine tools quickly. He said: "This is not just standardized equipment and procedures. The success of our production environment also depends on experienced workers. They can adapt to problems when they arise and they are willing to learn more and more." Tasks take longer, machinery Workers operate several machines at the same time, usually at the factory's "fourth shift." The fourth class is organized every 12 hours on Fridays, Saturdays and Sundays. Fixed shifters often evaluate the work and set aside that heavy workload or the same work to each other and leave it to the fourth shift so that the work does not interfere with the processing during normal working hours. K&L Microwave's Kitamura machining center is a two-tray system. Searing explains how factories use them to further shorten the work cycle. He said: "We did not start a job until it was completed. Instead, we loaded a few jobs on a tombstone mounted on a pallet. Then we went back and forth between these tasks. Each task may need to be operated. About 1 hour.” He said that this allows the factory to process up to 8 different workpieces at the same time in each machining center. Therefore, it can serve multiple customers at the same time. In addition, this limited run-time operation allows long-term flow of parts to assist downstream operations. No one needs to wait for parts. Searing also said that due to the inherent design features of the horizontal machine center, the assembly and conversion time of the orders are shortened. These machines quickly and efficiently cut out debris from the workpiece and drain the debris from the machine's cover plate so that operators do not have to waste time in changing pallets to do these things. Searing said that another design feature that helped K & L Microwave Company was the high spindle efficiency that horizontal machining centers have. Before using a horizontal machining center, the factory used a vertical machining center production line. Searing points out, "The spindles of those vertical machine tools are only about one-third of the time in metal cutting." Operators need to spend a lot of time turning parts. Remove the debris from the machine and the tool and install the tool.
