| + | == Basic rules for machine usage == | ||
| + | <br /> | ||
| + | * The machine is intended to be used by all (qualified) members of Hacklab | ||
| + | * In unclear cases the use of the machine is directed firstly by the superuser (Kremmen) and finally the owner's representative (rambo) | ||
| + | * Only those operate the machine independently who have received appropriate training and who have been deemed sufficiently skilled and sane to do so. Others may operate the machine under the direct supervision of a person qualified for independent operation. | ||
| + | * Dying is strictly prohibited! Dying without permission can be grounds for termination of membership! Do read, rehash and memorize the safety rules and work according to them. | ||
| + | * "I wonder what that button might do" is a BAD idea. If you don't know, find out in advance. Using the machine is not a right but an earned privilege. Several lab members have invested their hard earned money so that we might have this rarity in our use. Do treat it accordingly. | ||
| + | * The tools found in the magazine shall be calibrated and at least the length offset for said tools is correctly programmed in Lotta's tool offset table. If you don't calibrate a tool it must be removed from the magazine after use. Additionally, calibration must be performed according to the agreed procedure or if not, again the tool must be removed. | ||
| + | * If a vise has been fixed to the table, it has been | ||
| + | ** [[Rihtaus|aligned]] true with better that 0.1 mm precision (using the inside ends of the fixed jaw as reference). Use the beeper or dial indicator as instructed. | ||
| + | ** [[Työkoordinaatistojen ohjelmointi|programmed in work coordinates]] 1 (G54) and 2 (G55) with X as the left end of the fixed jaw and Y as the inside. The right hand side or only vise is 1 (G54) and the left is 2 (G55) if both vises are on the table at the same time. | ||
| + | * If you place a vise on an empty table, please note the clearance required by the magazine and the tools in it. If your workpiece is tall it may not have room under a long tool when the magazine advances to the tool change position. In such a case fix the vise closer to the right side of the table and home the table before tool changes. | ||
| + | * Allowed materials for milling are basically all others except porous stuff that soaks up oil and water to itself. For this reason '''wood milling is forbidden'''. Wood dust will dry out lubricated surfaces and together with cutting fluid it forms an intolerable putty that clogs all narrow gaps and leads to trouble. Ther are no exceptions from this rule. In unclear cases the machine superuser will determine whether a material is fit to work or not. Please do ask if unsure. | ||
| + | |||
| + | The precondition for operating Lotta is sufficient knowledge on machine handling<br /> | ||
| + | As a general rule this knowledge is acquired on introductory and basic training courses. Optionally a qualified instructor may guide a person in the use of the machine.<br /> | ||
| + | <br /><br /> | ||
| + | |||
| + | You get qualification for use of Lotta by passing the '''[[Operator's Test]]'''<br /> | ||
| + | |||
| + | At this time the following persons act as Operator's Test supervisors:<br /> | ||
| + | |||
| + | # Kremmen (Martti Paalanen) | ||
| + | # dist (Taneli Kaivola)<br /> | ||
| + | In all cases a named test supervisor must confirm an applicant's qualification as operator. '''Note that the operator is responsible for everything that happens at the machine'''<br /> | ||
| + | <br /> | ||
| + | At this time the qualified Lotta operators are: | ||
| + | * Kremmen (Martti Paalanen)<br /> | ||
| + | * rambo (Eero af Heurlin)<br /> | ||
| + | * dist (Taneli Kaivola)<br /> | ||
| + | * Heikkki (Heikki Salminen)<br /> | ||

| + | ==10 Commandments== | ||
| + | <br /> | ||
| + | # When the machine is hot it has exactly '''one responsible operator'''. He/she is answerable for all events around the machine until operator duty is passed to the next guy. | ||
| + | # When a person cold starts the machine he/she becomes the responsible operator from that moment onwards. | ||
| + | # Operator responsibility shall be handed over verbally in this manner: Arnie: "It is your machine" - Bernie: "OK, I got the machine". The key is that the receiver acknowledges the transfer of responsibility explicitly. Only then is the responsibility actually transferred. When you are the operator, DO NOT JUST SLIP AWAY without transferring the responsibility. If there is no-one to take over, turn the machine off. You can only transfer the responsibility to another qualified operator. | ||
| + | # Anyone can hit the EMERGENCY STOP button when observing a potential or actual hazard. '''Only the operator will release the Emergency Stop'''. | ||
| + | # Don't try to circumvent the machine safety mechanisms, especially the door interlocks. | ||
| + | # Don't dress in cloths with anything flapping around that could be snagged by a rotating shaft. Lotta is definitely stronger than your bones. | ||
| + | # During manual operation the machine allows safety doors to be open so that various adjustments are possible. Use your brain and don't put your hands too close to a rotating spindle. Be especially wary of large diameter tools that can have a surprising swing. | ||
| + | # When operating the machine, see to it that no hands are close to the spindle when starting it. | ||
| + | # Do not trust the machine to do what you want. It will do what you ordered it to do. Also G code has bugs! | ||
| + | # Do not distract the operator when he/she is concentrating on machine operation.<br /> | ||

Turvasääntöjen olemassaololla on kolme päätarkoitusta, ja prioriteettijärjestyksessä ne ovat:
Perussäännöt koneen käyttöön
Lotan käytön edellytyksenä on riittävät perustiedot koneen operoinnista Näyttökoe koneen käyttöön valtuuttamista varten. Same in English: Operator's Test Tällä hetkellä koneen käyttöön voivat valtuuttaa seuraavat:
Kaikissa tapauksissa valtuutetun kouluttajan on vahvistettava halukkaan pätevyys koneen operaattoriksi. Huomaa, että operaattori vastaa kaikesta mitä koneella tapahtuu.
