We are using the TMX 0075-50-14 thread mill tool from Scandanavian Tool Systems. What is the recommended feed and speed to cut 1018 mild steel with a 16 pitch insert in this tool. The cut is interupted. We are having problems with tool breaking.

All the manufacturers that I have dealt with regarding stepper motors plot the torque curves as "maximum continuous" torque. Peak torque is given, but it would seem meaningless to do a torque curve plot using peak values, wouldn't it? Is it possible to hold a motor at peak torque long enough to...

The most accurate homing sequence, given that you have a servo motor and I am assuming standard encoder with index pulse is as follows: Upon power up if home switch is not tripped, drive toward it until it is. Upon tripping the home switch, drive away until the switch untrips. Now continue to...

I use the opto-22 SNAP I/O over an Ethernet connection which is driven by a DOS target, using a 16-bit operating system. Been working trouble free so far. The only problem I encountered was my own failure to carefully read the manual. I did not take into account that the SNAP "Brain" reads and...

Your points are all well taken. One point I should have mentioned really has to do with avoiding my own errors. My references on tolerances calls out nominal sizes with tolerances shown as I had posted, i.e. 10 -.0025/-.0037". If I was asked to dimension ouside of the standard it would...

The other thing to keep in mind when you look at the torque curves for steppers is whether or not the curves where measured at full step mode or not. I am aware of some manufacturers that post curves based on full stepping the motors which show much better than the common usage which is...

The correct way to compute the power curve for this motor is Torque (Nm) * rps * (2*pi). The result is in watts.

Dimensioning in this fashion is common to the company I work for when designing certain types of assemblies. We manufacture machine tools. Fits are very important and dimensioning in this way lets the machinist know what your intentions are. For instance, lets say I wan't a cylinder assembly...
