Last week I brought the head of our 5 axis SCM tech 5 down onto the middle of the work piece sideways causing the HSK tool holder to nut to attempt to cut into the panel. (I had the wrong zone set, it should have come down, then machined the edge of the work piece)
At first I could not find any real damage, however since I have had a lot of tool change issues, the head will come down to pick up a tool, attempt 3 times, then throw up a tool insertion error.
SCM tech services tell me I may have knocked the 'B' or 'C' axis out of alignment, and they need to use a rectified rod and a dial indicator to re align the axis. anyone been in this situation before? calling out a tech is expensive and the owner of the company is not to happy with me!
Sorry about your crash. Unfortunately, when you have a machine crash with any real velocity, the chances of pushing a work unit(spindle) out of alignment is quite likely. With a 3/4 axis machine, the supervisor or operator can easily adjust the unit, or adjust the parameters to put everything back into spec. My advice is to get a technician in and assist in the realignment process so that you can do it yourself in the future. Take notes and get a list of tools that you will need to perform this yourself. This will happen again, because of set up, or programming errors. Not everything is in your control, but if you learn well, your ability to adjust the machine will be invaluable. Money well spent. Remind the owner of that if he grumbles.
I ran a MotionMaster 5 axis before retiring. I would never start a program without having my hand on the potentiometer. Even then I had a couple of minor crashes. Most of them were mistakes on cutter length. Yeah I know, stupid stuff! Can't you see the error in the cuts? Cut some thicker material, check square to the table, rotate the head 90 degrees and run another piece, repeat, etc.....I would also suggest you should be able to see misalignment when it drops off the old cutter before picking up the new one. Mike is right, no one is perfect. Sure the boss might not be happy, but I bet he can't come out and run the machine like you can. He'll get over it if you learn from the mistake and make him more money!
FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards(return to top)
WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
A valid email return address must be included with each message.
Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
Subject lines may be edited for length and clarity.
"Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
