Workpiece Setup: The workpiece is securely clamped or held in place on the drilling machine's worktable or fixture. The workpiece may be made of metal, wood, plastic, or other materials.

Tool Selection: The appropriate drill bit is selected based on the size and material of the hole to be drilled. Drill bits come in various types and configurations, including twist drills, flat drills, center drills, and step drills, each suited to specific applications and materials.

Drill Bit Installation: The selected drill bit is inserted into the chuck or collet of the drilling machine's spindle and securely tightened in place.

Setting Drilling Parameters: The operator sets the drilling parameters such as drilling speed, feed rate, and depth of cut based on factors such as the material being drilled, the type and size of the drill bit, and the desired hole specifications.

Execution: The drilling machine is activated, and the rotating drill bit is fed into the workpiece to create the hole. The drill bit cuts into the workpiece, removing material and forming the hole to the desired depth and diameter.

Chip Removal: During drilling, chips or swarf are generated as the drill bit cuts into the workpiece. These chips must be effectively removed from the hole to prevent damage to the drill bit and ensure accurate hole dimensions. This is typically achieved using coolant or cutting fluid to lubricate and cool the cutting process, as well as chip evacuation systems such as peck drilling or through-spindle coolant.

Finishing and Deburring: After drilling, the workpiece may undergo additional operations such as countersinking, counterboring, or chamfering to achieve the desired hole features and surface finish. Any burrs or sharp edges created during drilling are also removed to ensure the quality and functionality of the finished part.
