Hey Everyone, I was playing around with breaking in a new Haas VF-4SS, and made just a few modifications to the Spindle Warm-Up Program. To be clear, this isn't a "spindle break-in program"; it is used to "fully warm-up the machine", after it has been sitting for a while. This program should take anywhere from 10-30 minutes to run, depending on how you have the setup configured. I added a few features that I thought would be useful to 80% of users, out-of-the-box. Feel free to use, modify, or distribute this Macro; but use it at your own risk! Selway Machine Tool Company is not responsible for any damage that should occur as a result of you using this Macro. This Macro causes Machine Motion, which is the whole purpose of it, but that cause a collision on your machine, if you aren't careful. No Warranty is expressed, or implied, if you choose to use this code. ----------- Ok, legal disclaimer out of the way, what does the Macro do, and How do you use it? What it does This Macro Program is designed to be run in 3 phases: Positions to 'safe start' location, and warms up the spindle by commanding Forward and Reverse alternately, through the RPM range, up to about 6,000 RPM. Then it ramps up to 12,000 RPM, and then "ramps down in reverse" (M04). This is the "initial spindle warm-up". It takes about 3 minutes, 10 seconds to complete. The machine then moves to the "home position" (controlled by variables, and user-defined). This is in "Machine Coordinates", and No Tool-Length-Compensation is used, so be careful! Once at the "home position", we turn on the Spindle at the "start RPM". We then "stroke the machine" in XY, and then in -Z. At the bottom, we increase the spindle speed by the Spindle Increment (default is 500 rpm). The "stroke to the endpoint", is done at "high feed" (variable). The "return stroke" is done in reverse, at the "slow speed". At each point (Start/End), the RPM increases, until we hit the "max RPM". That RPM increment is what breaks the "WHILE/DO/END" Loop. After we have "fast stroked/slow returned", the process is reversed. The machine follows the same "positions and strokes", but goes "slow stroked / fast returned". Each of the "stroke cycles" takes about 6 minutes, on a VF-4SS, with 500 RPM as the "increment", 800 IPM as the "fast feed", and 200 IPM as the "slow feed". So, roughly 18 minutes to do a "full warm-up". But what does this get you? A fully warm, and lubricated spindle. A fully warm, and lubricated set of Linear Axes. At the end of the Macro, the program sets the "S" value to a "safe RPM". (Default 80 RPM) It also sets Spindle Direction to CW (M03), and orients the spindle at the end of the cycle. How do you use it? There are Machine Variables at the top of the Macro, which control the following: Make sure you load a Short and Balanced Tool Holder. Gauge Length should be kept to a minimum. (I used a 2.5" OAL Holder for this test.) #10301 through #10303, control the XYZ Home Position. Typically, all three are 0.0, however, on a machine where there is added travel "above the Z Zero Point", you could have something like #10303=4.0. #10304, #10305, and #10306 control the "XYZ Stroke Position". This is the "endpoint" in Machine Coordinates, of each Axis. WARNING: Make sure you adjust all three of these numbers, if your machine is not a VF-4!!! BE VERY CAREFUL WITH THE -Z STROKE! This Macro does not use Tool Length Compensation. We are driving the "gauge point" of the spindle, not the Tool Tip. At the end of the cycle, there is a "Park Position". This is #10324, #10325, and #10326. This is the final place where the machine stops after warming up. It is possible to change either the "XYZ Start" position, or the "XYZ Park Position" to use any of your Work Offsets. BUT BE CAREFUL! For example, consider if we set XY Park to #10324=#5221, and #10325=#5225, but set Z as follows: #10324=#10303. This would put us at G54 XY, but "Machine Zero" for the Z Position. Feel free to experiment and modify this Macro to suit your own needs, but I highly recommend the following: Run the program through in Graphics Mode 1st, before running it on the control. Turn down the Feed and Rapid Overrides, until the machine has cycled through a complete "stroke" of XYZ. The cycle is designed to -Go Home, -Stroke XY, -Stroke Z, -Return Z, -Return XY. Once you have completed a cycle, and you see the WHILE/DO Loop is "incrementing the Spindle Speed", you should be safe to set Rapid and Feed to 100%. Just remember you're still responsible for operating the machine safely. Make sure you check for clearance, and that all "Park, Stroke, Home, Feed, and Spindle values, are set appropriately for your machine. If you only have an 8,100 RPM Spindle: Remove from N222 - to - N233.
