Torq-Tenders positive-drive couplings provide accurate overload protection in virtually any mechanical power transmission system, and are available in custom models and sizes. These are mechanical torque-limiter couplings that disengage motor drives when torque is exceeded to protect the entire system. When load exceeds the Torq-Tender rating determined by precision-tempered torque springs, the units' drive key pivots out of a slot to disengage the Torq-Tender coupling. Once the overload is removed and the speed reduced, the units automatically resets themselves.

Among the designs available is a through-shaft, bushed model where applications require a drive shaft extended through the complete Torq-Tender unit. There are designs that include face-mount, end-of-shaft models, end-of-shaft self-supporting models, and variations within each model to accommodate special input bores, splines, housings, and non-standard mountings. The smallest standard Torq-Tender is the TT1X with a 2 to 60 in.-lbs, torque rating. The largest is the TT4X with a 750 to 3,000 in.-lbs, torque rating. Zero-Max, 13200 6th Ave. N.,

Mastercam Version 8 delivers dozens of new features including full toolpath/geometry associativity, enhanced surface and solid machining, and high-speed machining motion.

Full associativity simplifies programming and modification of all milling operations including pocketing, contouring, drilling, multi-surface roughing and finishing, and multi-axis machining. Geometry and toolpath are linked so when the model or tooling information is changed, an updated toolpath can be generated with a single mouse click. Users can drag-and-drop parameters, toolpaths, and tool definitions from one operation to another, and can create a library of common operations to apply to new models. In addition, the software includes several methods for running standard toolpaths at high speeds.

IMAQ Vision Version 5.0 can be used to build versatile, easy-to-use vision applications that incorporate high-speed pattern and color matching. It can quickly detect common errors in the manufacturing process, such as misplaced or misaligned components and gross solder defects. The interactive environment of LabWindows/CVI, which is a component of the company's Measurement Studio, makes it easy to take advantage of the power and flexibility of C for vision applications. Finding objects with traditional techniques is slow when compared to IMAQ pattern-matching software, which in test cases using a Pentium III MMX 500 MHz computer, found objects in less than 20 ms.

The software can identify missing or misplaced components, misaligned parts, loose or skewed parts, rotated and reversed parts, incorrect component size, excess solder and solder bridges, bent or lifted component leads, and color discrepancy.

A line of retaining tings has been made according to world standards, including inch, metric, DIN, and JIS (Japanese Industrial Standard) to fit virtually any application.

The retaining rings are as effective as traditional fasteners like screws, nuts, bolts, cotter pins, and washers, but cost less in installation and materials, says the company Retaining rings also reduce waste associated with machining shoulders and treads, making them an environmentally sound choice over traditional fasteners.

This new conversion module converts servo motor control signals to stepper motor control signals. It can control four independent stepper motors. The Servo-to-Step is an active termination panel that converts a [+ or -] 10 V signal to the stepper CW/CCW (direction) and STEP (clock) signals. If the stepper motor doesn't have an encoder for position feedback, the board can be configured to synthesize quadrature signals. The maximum stepping rate is user-selectable via a DIP switch from 7.6 Hz to 31.25 kHz. Motor direction and enable are also configurable.

The unit will work with any servo motor control software that uses analog voltage for velocity and incremental encoder pulses for position feedback.
