The following Drilling cycle types are available:
-
Single peck — Drills the holes in one operation.
-
Deep drill — Drills the holes in several stages (multiple peck).
-
Break chip — Drills the holes in several stages (multiple peck) only retracting a small amount after each peck.
-
Tapping — Drills the holes in one direction and reverses out.
-
Rigid tapping — Enables you to enter a Peck depth as well as a Pitch.
-
Helical — Bores out a large hole with a small tool. The concept is similar to trochoidal milling. The difference between the two is that trochoidal milling machines a slot (no variation in Z) and helical milling drills a hole (machines down the Z axis).
-
Ream — The first of the boring cycles (G85).
-
Counter bore — The second of the boring cycles (G86).
-
Profile — Drills the hole using circular moves. A tool smaller than the size of the hole is required. At each depth, the tool moves on to the edge of the hole using a circular arc lead with a straight extension, cuts a circle, and then moves back to the centre with a circular arc lead and straight extension. You may use a thickness value to create a smaller hole.
-
Thread milling — A cycle similar to reverse helical but with improved leads in and out for thread creation.
-
External thread — Creates an external thread on a boss.
-
Fine boring — An alternative deep drilling cycle, so may be used for machines with a variety of deep drilling cycles.
-
Deep drill 2 — A second deep drill cycle where the drilling is performed in several stages (multiple peck).
-
Reverse helical — A second helical drill cycle. This bores out a large hole with a small tool. It performs a helical movement from the bottom of the hole. Use this for finishing a hole as you can use it only with a pre-drilled hole.
-
Cycle 1 to Cycle 5 — Alternative deep drilling cycles. Use this option on machines with a variety of deep drilling cycles.
-
Bore 3 to Bore 5 — These correspond to the third, fourth, and fifth type of boring cycle (G87-G89) normally found on a machine tool. The difference between the boring operations varies from machine tool to machine tool.
