How to write a program for fanuc robot parts

The primary focus of this position is to support the manufacturing operations team by maintaining all machines and equipment in the fabrication area of the factory to ensure welding departments are able achieve plant production goals. Ensure all production equipment is properly maintained and in working order. Perform reactive, predictive and preventative maintenance within the facility through inspections, mechanical adjustments, electrical testing, lubrications and repair of equipment. Associates degree in electrical systems or weld engineering would be a plus.

The Drilling Cycle Two important factors in the drilling cycle contribute to premature drill wear. Absence of dwell at the bottom of a hole or peck and rapid traverse down to the exact bottom of a hole for succeeding pecks.

The reaction time of CNC equipment is all but instantaneous. When a drill, feeds its way down into a hole and reaches the bottom of the hole; or the end of any peck it changes direction to 'Z' up. It also changes into rapid traverse. In other words the drill is literally snatched out of the hole.

Twist drill geometry incorporates right hand spiral flutes. The flutes intersect the cutting edge to form a positive back rake angle.

Under feed a chip flows up the flute and therefore lays over the cutting edge. This overlay condition resists the retraction of the drill.

Through this, resistance forces develop which work against the cutting edge trying to flake it away from the drill body. Drill geometry is designed to support the drill point under tremendous cutting pressure while spiralling down into the work. Yanking the working drill from the hole causes these forces to change direction on the cutting edge at an angle down and away from the drill body creating an effective high negative back rake.

On retraction the drill shears the chip off using the fragile cutting edge. The result is either abnormal abrasion, chipping or breaking off the cutting edges.

Also after leaving the hole a crested bump is left at the hole bottom because the drill point did not finish making the chip before retracting. If the returning drill is going in for another peck it could rapid to the bottom catching this bump and experience excessive cutting forces again chipping the cutting edges.

A fix for this problem is to program a dwell long enough to hold the 'Z' axis drill position for one to two spindle revolutions letting the chip thin out to zero.

Retraction at this point would not damage the tool. This length of time at RPM would be approximately 0. To figure this time increment divide the RPM into 60 seconds. Three hundred RPM would equal 0. Most machining centers have several canned drill cycles which are used to drill holes.

A G81 spotting or shallow hole drill cycle has no programmable dwell, although popular and okay for through holes it is not a good choice to use in blind holes. A G82 drill cycle has dwell that can be programmed.

This G82 cycle is a good replacement for a G81 when used for drilling holes through or three drill diameters deep. In fact a G81 can be completely eliminated.

Deep Holes Peck drilling is generally required when drilling holes deeper than three and one half drill diameters. Most canned pecking cycles allow for starting the feed rate just above the last peck to prevent the drill from hitting the hole bottom at rapid traverse rate.

The difficulty is that no dwell is available at any peck bottom except the last. So no effective method exists to prevent the chip breaking action from causing severe tool damage. Some people think this tool damage comes from heavy feed rate. Light feed rates are then programmed to solve a problem which should not exist in the first place.

The net result is lower productivity. A New Subroutine A temporary work-around is to build a special pecking cycle.

The pecking cycle would incorporate a dwell at the end of each peck for a time length sufficient to allow one or two drill revolutions. Another approach would be to change the drill feed to up, or Z plus, for a few thousandths.

This would allow the chip to thin out at the end of the peck just before retraction. This approach would not be a dwell but a feed reversal and would thin the chip and also position the drill away from the hole bottom to prevent work hardening the material.Create weld parameters and robotic weld path programs for OTC, ABB, Fanuc, and Panasonic robotic weld systems as well as Nachi material handling systems.
