This lightweight and practical, four component dynamometer measures the cutting forces in any drilling process. The measured values can be read on the internal display or on a large external display using auto-hold. The PC-based data acquisition is performed over the built-in USB interface with the included software for tool dynamometers. Over the same interface the device parameter setup for wear detection is executed. After the setup, the device is able to supervise a drilling process without a connected PC. With this great properties the device suits multiple educational and industrial applications.

Wear detection

Our tool dynamometers for drilling and turning implement a function for supervising and documentation of wear progress in any cutting process. This is achieved by comparing the Fc/Fp relation. Using our cutting software, the maximum value is teached in by PC. When exceeding the maximum, an alarm occurs. The current distance to the maximum is shown on the internal display in 10%-steps. After wear detection setup, the tool dynamometer is able to work independently from a PC.

Internal display

Auto-Hold

This function provides manual data acquistion by reading data from the internal or external display. It implements an automatic detection of the stagnation of a cutting process, determines the average value and gives the operator a signal to collect a measuring data record. The operator stops the process. Now the value can be comfortably be read on the display. Disturbance created by scraping chisel is automatically filtered.

The model uses a belt drive that submerges downtrum into an oil reservoir . So transports oil on its surface. Upside a plate is placed which can be inclined and the distance to the belt adjusted. Above the plate a number of glas tubes is arranged having connection with the oil film via small bores. The tubes are graduated so is readable the pressuredistribution of the oilfilm.

Parameters which define the portability of the bearing are:

• inclination angle of the plate
• thickness of the oilfilm
• Relative speed
• viscosity of the oil (often a function of temperature)

Description:

The model has got a loading device in the form that a slide can be differently pressed against the traversebolts. The spindledrive now has to overcome the more resistance, the stronger upper and lower slide are screwed together. The handwheel has got the scaling 250. This corresponds to the spindle gradient 2.5 mm The dial gauge 5mm/0.001mm is set axially against the spindlenut to measure play.

• Determination of the spindle gradient
• Determination of the division of the scaledrum in units of slide feed
• Determination of spindle play dependant on load and degrees of nut- and bearing compression.
• Dismounting the device to learn the design of the spindle bearing
