- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
In a collaborative effort to best enable 5-axis machining for users with Heidenhain TNC controls and Mastercam CAD/CAM software, a new collaborate post-processor is now available. Called the Heidenhain TNC 5X Mill post-processor, CNC Software Inc., developers of Mastercam software, introduced it after coordinating development efforts between the two companies. Collaboration also included beta testers and industry resellers in order to best meet the worldwide demand of providing a consistent, high-quality Heidenhain translation post.
All Heidenhain control users that use Mastercam CAD/CAM software can now benefit from this newly developed processor, including those using iTNC 530, TNC 620 and TNC 640 controls.
“Heidenhain is committed to ensuring that our control customers have the tools they need during any 5-axis machining application, and this collaboration post-processor is just one example,” explained Gisbert Ledvon, Heidenhain TNC business development manager. “We are now experiencing an increased demand in North America for our newest TNC 640 control for high-precision 5-axis machine tools, and we want those customers to know that if they have Mastercam software, we are dedicated to providing ongoing translation updates as needed!”
