centres and 3 NC lathes, (he FMS consists of 3 groups/lines of FMS I, FMS II, and FMS III to allow the machining of works in all sizes and configurations. The lines arc fully operating day and night at the extensive plant which has a building area.
The capabilities of each line are as follows. The FMS II is a large-sized, prismatic parts machining system line which is regarded as the most effective of all. This line is designed to machine cads, columns, saddles and other components of a machine tool Arranged in line are 4 machining centres. These machines art connected by a 1-axis CNC-controlled unmanned rail trailer (60 m/min) which has a 6-ton loading capacity and employs linear motion bearings. On the right hand side of the line, there are setup stations and an oversized work setup/reversing unit to permit safe and effective setup. Pallet stockers are also disposed opposite t the machining centres across the rails to effectively utilize a space usually occupied by pillars.
Chips are collected at an accumulation hopper by a chip conveyor. When a certain weight is reached, the port of the hopper opens to remove chips to the outside of the plant. Chips on a pallet are also removed by a cleaning station.
Previously, fixtures posed a problem to the machining of single-item parts. The fixtures for the line have been standardized to permit the line to machine the aforementioned parts 100% by the combinations of the standard fixtures.
"Automatic Edit" of 528 Tools
The FMS III is a medium- and small-sized, prismatic parts machining system. The FMS comprises a total of 4 machine tools i.e. 2 horizontal-spindle machining centres and 2 vertical-spindle machining centres, and also an automatic tool supply unit, an un manned rail trailer, stockers, and a stacker crane. The main point; of this system are the utilization of standardized pallet clamper; which allow the effective machining of works from one machine to another and also the facilitation of system shutdown and production smoothing. The highlight of the line is the first trial of an automatic tool supply unit consisting of a tool robot and an automatic warehouse. Receiving a command from the CPU, the automatic tool supply unit "automatically edits" required tools (4 tools x 2 rows) by selecting them from the tools stored in the automatic warehouse. The supply unit transfers the tools from a too; fixture to a buffer stocker and supplies desired tools to desired machines from the machine front side by the trailer. In machining priority is given to the tools. Upon completion of group machining, the tools are collectively changed. The time required for this tool changing is said to be only 5 to 6 minutes. |
Full-Scaled Round Parts Machining Line
The FMS IV is a middle- and small-sized round parts machining system line which has been so automated and unmanned that one may question why such high cost performance is possible. This system comprises a total of 4 machine tools, i.e. 3 NC lathes with robots and automatic chuck jaw diameter shifters and 1 horizontal-spindle machining centre with the robot, and also 1 automatic tool supply unit (with two 5-stage 24-row tool magazines), 1
oft jaw cutting attachment, 2 unmanned rail trailers (350-kg
lading capacity), 96 pallet stockers for more than 16-hour nighttime unattended operation, and 1 setup station.
A cell system comprising a combination of the trailers and the robots is utilized for the machining sequence of turning, drilling,
and milling. A universal chuck is used for the machining centre.
he pallet is of a cartridge type where 50-mm diameter and 300-mm length works arranged in line. The pallet can afford to load 3
to 6 works depending on work sizes. It is said that 1 hour is the machining time of works on 1 pallet.
The automatic chuck jaw diameter shifter (AJS) is provided to meet a variety of works. NC machining data are incorporated with
program which allows the automatic machining of soft jaws.The
block tool magazine is an overhead travelling type tool loader and automatically changes tools.
One can immediately understand that the aforementioned line к designed for the full machining of round-shaped parts therein, including not only turning but also drilling and milling by incorporating the machining centre. To achieve the unmanned operation of the turning line which requires short machining time of only within 1 hour for works in 1 lot size, the supply of works, the NC machining program, and the motions of the robot have been synchronized with each other, and also jaw shifting, soft jaw cutting, and tool supply have been automated. The line is full-scaled in that it is heavily equipped with the aforementioned automatic units.
New Software
As aforementioned, the FMS is incorporated with new software technologies. Major technologies are as follows.
Firstly, work scheduling software.
A daily program is made in units of parts on the basis of a production schedule. Due to the diversification of products, however, parts must be supplied synchronously with the assembling or the next process. For this purpose, a system may not be enough to be capable of the conventional lot production. It must be able to reduce in-process time and increase the number of machined work types per day. As for this aspect, a load simulation system |
